The Difference Between Metal and Wood Lathe Chucks

Posted on by

A lathe chuck is a clamp that is used for holding the lathe’s rotating tool bits. You can find the lathe chuck in a push or a pulled design. The push version is tapered and works by using a threaded cup. This pushes the bit deep into the socket to make the clamp. The pulled design has a section that is threaded near the back of the tool. This pulls the chuck in tight by use of the grooves.

 

Lathe Chuck Information

The lathe chuck can be used for either metal or wood lathes. It is important to know the differences between them so that you will be able to choose the right one for you. Of the different models, the most popular is the three and four jaw. The grip on the cutting tools and drill bits is firmer which is necessary for harder materials. When thinking about cost, the wood lathe will cost you less than a metal one. However, you need to consider what types of jobs you wish to do before deciding what one to buy.

 

Information on Wood Lathe Chucks

The size for wood lathe chucks is most often 0.25” or 0.50”. However, you can find them in other sizes if necessary. These are used to turn wood for a bowl, pens, cue sticks, baseball bats, table legs, etc. Because wood lathes are not as sturdy, the motor does not have to be nearly as powerful as a metal lathe. A wood lathe should not be used for materials that are harder than wood. Wood Lathes turn faster and do not make cuts that are as precise as metal lathes. While they are less expensive than metal lathes they do not make very good substitutes.

 

Information on Metal Lathe Chucks

Metal lathe chucks are used for hard materials. A metal lathe has a much more powerful motor than a wood lathe. You can also guarantee more precise cuts from a metal lathe. A metal lathe does not need to be hand held. The tool itself is incorporated into the machine that you use. A metal lathe chuck itself is a heavier tool when compared to a wood lathe. If necessary, you can use a metal lathe for any wood projects that you may have.

 

Some Safety Tips

When using a lathe, whether it is metal or wood, safety glasses should always be worn. These will help protect your eyes from debris and dust. You should never wear gloves when using these machines as the gloves can easily get tangled while the machine is in use. You should also never wear loose-fitting clothing for the same reason. If your hair is long, then you should have it tied back while using these machines. You need to wear protective footwear, preferably steel-toe boots. Some woods contain dust that can be hazardous to your health. Wear a helmet that has a respirator built in or a dust mask. Be sure to thoroughly read the manual for this machine before you attempt to use it.

What Is A Deep Hole Drilling Machine?

Posted on by

Do you know what a deep hole drilling machine is? Have you encountered this type of machine before?

 

A deep hole drilling machine is a mechanism used in the process of deep hole drilling. Commonly, it is used to produce deep, straight holes especially in metals particularly in the process of gun making. Deep hole drilling machines are the best mechanism to produce accurate holes necessary for most manufacturing processes.

 

Deep hole drilling is the machining of holes with a relatively large depth to a diameter ratio. Essentially, any hole deeper that ten times the diameter of the material should certainly constitute the process of deep hole machining. Specialized drilling technique should be considered in dealing with these processes.

 

Interesting to note as well: deep hole drilling machines were initially developed for manufacturing of guns and armaments. It was used to drill gun barrels. Throughout time, however, other industries also saw the potential of this tool. Nowadays, a lot of industries such as energy, oil and gas use gun drilling machines for resource exploration. It is also useful in the metal cutting industries, automotive, aircraft, petro-chemical industries. Gun drilling mechanisms are also found useful even in the medical field.

 

Construction of deep hole drilling machines is not only expensive but a difficult task as well. It requires specific planning and a variety of tools and machinery. Despite the difficulty of production, deep hole drilling machines are still seen as an important machine in most processes in different industries.

 

Depending on the required processes, there are different kinds of deep hole drilling machines. As a machinist, you have to consider the dimensions of the machine you are going to use, and the dynamics of the materials. In addition to the machine dimensions, power and dynamics, compatibility of these tools with various machines is primarily determined by the fluid delivery and chip exhaust systems. Achieving a perfect deep hole is not only reliant to the drilling machine but to a variety of mechanisms or systems. The two most common deep hole drilling systems enforced by different industries are gun drilling system and the BTA system.

 

Here is how a drill machine operates in the system of gun drilling: the drill is positioned and held in a spindle nose. It is then guided to a pre-started hole to avoid vibration of the drill. With this setup, the gun drill system operates in full accuracy. The high pressure coolant flushes the chips and lubricates the system. This operation produces the fine finish and burnished surface of the hole.

 

Important to note as well that, in using a drilling machine, safety precautions must be enforced. As with all power equipment, safety and security of you and your environment plays a crucial role. For instance, you must wear the correct and appropriate working clothes in using a deep hole drilling machine. An appropriate uniform lessens the possibility of an accident. Make sure also that you know how the machine works so that you can preempt an incident waiting to happen.

Transformer Winding Machines: Significance and Types

Posted on by

Transformer is one of the most crucial components of any electrical circuit. A transformer is basically used to convert (increase or decrease) the voltage, depending upon the maximum allowable voltage of an application. Thus, there are two main types of transformers, namely, step-up and step-down transformers. The main difference between these two types of transformers is the number of windings. Thus, winding becomes the most important part of this electrical device. These windings are manufactured with the help of transformer winding machines.

 

Transformers are used in a wide range of applications varying from a mobile charger to huge industries. Thus, the rating of the transformers can vary from VA to MVA. VA is the voltage and current rating of a transformer. Thus, based on the applications, transformers with different windings are used. There are different types of transformer winding machines used to manufacture transformers with different VA/MVA ratings. Besides this, different types of winding machines are required, depending upon low volume or high volume production. What are these machines? What is the significance of these machines in manufacturing winding? Are you intrigued to know more about them? Read the following post to get a detailed understanding of these machines.

 

What Are the Types of Transformer Winding Machines?

 

As discussed earlier, transformers with different VA ratings require different coil winding machines. Based on this, there are three main types of winding machines used. These three types of machines are as follows:

 

  1. Manual Transformer Winding Machines –

These transformer coil winding machines can either be operated by hand or with the help of a small motor. Transformer coils can be wound precisely by using the manual transformer winding machines. One of the major advantages of these machines is that they are light weight. This makes them portable and can be carried from one place to another easily.

 

  1. Programmable Transformer Winding Machines –

The programmable transformer coil winding machines are an advanced version of winding machines, which feature a 16 Bit microprocessor for smart operation. These machines also have a stepper motor, which is capable of winding up to 750 RPM. In these machines, various functions of a transformer are set-up and programmed. This is one of the biggest advantages of these machines, as programming these functions provides high level of precision in operation. Thus, coils of transformer can be wound easily. Some striking features of this achiness are:

 

  • They have a built-in production counter, which keeps an eye on the number of transformer coil winding.
  • There are a number of menu items, which can be programmed easily.
  • These winding machines are equipped with a speed control knob. This helps adjust the speed.
  • Another important and beneficial feature of these transformer winding machines is that they have a display.

 

  1. Automatic Transformer Winding Machines –

As their name suggests, the automatic transformer winding machines do their job with no or very less need of human interference. The advantage of using these types of winding machines is that they help reduce the labor costs. Various tasks can be fed to these machines, and they are operated using computerized programs. The multi-spindle feature of these machines help to make the equipment multi-coil winding. Multiple coil windings can be done simultaneously using these types of machines.

 

These were the three basic types of transformer winding machines used by a number of manufacturing firms. If you want to get more information about transformer coil winding machine, try to check out the website of DETZO Co., Ltd. – the company specializes in producing fully automated production line and winding machines. Learn more details please do not hesitate to visit DETZO immediately.

How to Increase the Process Speed of Die Sinking EDM

Posted on by

Developments in the EDM process and its technology along with improvements in accuracy, automation and micro-mold making technology can pay enormous dividends to the domestic mold making industry.

 

Speed Is Not the Solution

Increasing drive speed is one solution to improving the speed of die sinking EDM. In this way the unproductive times for lifting movements are reduced; however, the gain in speed is limited to small electrodes and very deep cavities. In addition, above a certain speed the electrode wear is considerable and very high axis speeds result in extreme strain on the mechanism, make the machine more expensive and shorten its working life. Therefore, it is wrong to believe that a general increase in the process speed is only to be achieved by rapid lifting movements. The contribution of fast axes to the machining process is just one supplementary aspect to a complex interaction that encompasses the generator, process control, gap width regulation and the mechanism. And die sinking EDM requires intelligent flushing.

 

Potential Lies in the Flushing

You can imagine the EDM process as being a balance between the EDMed and evacuated material in the gap. If this balance is not present, then either you flush the machining area unnecessarily—involving a loss of time and additional instability of the process—or you EDM the same particles several times, which cannot be removed from the gap sufficiently.

 

Die Sinking EDM

Before the material can be evacuated from the gap you must remove it from the workpiece. So how can you achieve more removal? As in the case of all optimization problems, the greatest gain potential lies where the efficiency is smallest. The efficiency of a single discharge with a cathodic poled workpiece is theoretically about 25 percent.1 In addition there are some factors that make the efficiency even worse (e.g., process control problems, non-ideal flushing conditions, small gap width), so that realistically you must reckon with an efficiency of less than 10 percent.

 

Removal and Surface Quality Determine the Time Requirement

In the case of EDM, the objective is always to optimize the removal performance of the machining on one hand, and to achieve the surface quality of the workpiece to be machined on the other hand. The workpiece, when machined, is intended to display a certain final roughness and a certain form precision. In addition, two conditions are called for:

 

  1. As small a thermally influenced area of the workpiece surface as possible
  2. As low an electrode wear as possible.

 

These marginal conditions determine the machining time and costs for workpiece production. In practice, a sequence of technological parameters is used because starting out from the roughing to finishing settings, the pulse energy is gradually reduced until the required technological results are achieved. Once again the law of nature applies: you can quickly achieve results of modest quality, but only slowly results in high quality.

 

Physical Processes Show a Solution

The approach toward an ideal state means moving the characteristic curve in the direction of the arrow. That means faster EDM with the same gap width, roughness and wear. If, up to now, the discharge energy of the EDM pulses was increased, regrettably you also only had greater roughness and a greater gap width so that the gains in speed during roughing were lost again through longer finishing. You will find a way to a solution if you return to the basics of EDM theory—to the physical processes leading to the formation of the spark and metal removal.

 

During the discharge, you can identify three main physical phases in succession:

 

  1. The Build-Up
  2. Discharge
  3. Fade Phases

 

In the first phase the discharge canal is built up. After passing through the working medium, the current flows almost exclusively on the surface area of the discharge canal and the anode is partially evaporated by the electron bombardment. The electrode wear mainly takes place here. Every pulse—whether contributing intensively to removal or not— causes microscopic wear. In the discharge phase, the electrical energy supplied causes melting or evaporation of material mainly on the workpiece. The fade phase begins with the switching off of the power supply. The plasma canal collapses and the partially evaporated, partially liquid material is ejected.

 

When to Interrupt Pulses

During the discharge, a crater forms in the workpiece. Fundamental studies of discharges have shown that the growth of the crater in the workpiece stagnates from a certain time. This is because a balance forms between the energy supplied and the energy lost, as well as energy that is used for the maintenance of the plasma and the heat loss to the workpiece and dielectric. This asymptote of the crater growth can be recorded in real time from the spark voltage and current.

 

However, why is the asymptote of the crater growth so important? Because this is the right moment to interrupt the pulse. It is unnecessary to let a pulse last longer if the target radius of the crater and the required roughness have been achieved. You can begin with the next pulse immediately. The time required by the pulse to reach this state also is not constant, as the speed with which a discharge reaches a certain spark base diameter depends on the macroscopic situation in the gap and the local geometry in the spark discharge area. With this first measure alone, you will optimize the number of discharges per unit of time and increase the removal rate.

 

When to Increase the Current

If you now observe the charge’s fade phase you will see that the removal from the workpiece is caused by the collapse of the plasma canal. The sudden drop in pressure—triggered by switching off the power—causes the evaporation and ejection of superheated material. The plasma canal has a very high temperature and pressure. The gradient of its collapse influences material removal. The more abruptly the energy disappears, the better the crater material will be ejected. In order to enhance this effect, a special trick is employed: before the pulse is interrupted, the current is increased briefly. The idea of increasing the pulse current is not new, the innovation is the definition of the point in time when this increase is to take place. The increase in the pulse current has no consequences for the roughness, wear or gap width, but does increase the removal. In addition, as the removal per pulse is greater, you need fewer pulses for the machining, and therefore the wear sinks.

 

Removal Rate Doubles in Part

This new machining strategy (asymptote detection, current increase and pulse interrupt) is the subject of a patent application for its use in new EDM die sinking systems. The results are in accordance with the theoretical reflections, especially where good flushing is guaranteed (e.g., pre-machined workpieces). For these machining jobs removal rates have doubled.

 

Generator Brings Striking Improvements in Performance

The innovative generator offers an increase in productivity of approximately 30 percent; however, up to 100 percent with pre-milled molds that occur increasingly nowadays through synergies with HSM. This refers to all roughing and finishing using copper and graphite electrodes. The advantages are particularly great with good flushing conditions and pre-milled workpieces. These convincing results explain that it is possible to increase the speed and productivity of die sinking EDM, and the potential for improving this technology is still considerable.

Buying a Five-Axis: Selecting the Right Machine

Posted on by

Horizontal or vertical? Trunnion or swivel head? What’s the effective difference between different configurations of five-axis machining centers?

 

Not all 5 axis machining centers are alike. Here’s where the application for which they will be used must be considered. You need to know what cutting speeds you’re going to run, for example. The type of spindle, the arrangement of rotary axes, rapid traverse rates, feed rates and available horsepower are other major considerations. Do you intend to machine primarily aluminum, stainless steel or titanium? How rigid does the machine need to be? What surface-finish quality do you require? What part accuracy are you trying to achieve? These are all questions you’ll need to answer in order to select the right machine for your application.

 

If you’re primarily machining aluminum, you may prefer a spindle capable of higher speed, such as 20,000 rpm, with higher rapid traverse rates, especially if you’re using smaller-diameter tools. Likewise, if you’re machining stainless or alloy steel for complex mold surfaces, you will likely be using small tools and high spindle speeds to achieve exceptionally smooth surface finishes.

 

Be aware that some machines are designed for cutting only aluminum. Others are suitable for steel and tough alloys, which require more rigidity, higher horsepower, lower spindle speeds, slower rotary speeds, higher torque and stronger box ways to make deep cuts with bigger tools. Machining different grades of steel, titanium alloys or even harder materials may require a heftier machine; however, this hefty machine would need to rotate the table excessively fast to achieve adequate surface speeds for cutting aluminum. The result might be disappointing.

 

When specifying out a five axis machining center, obtaining the expert advice of an experienced engineer is recommended.

 

Horizontal or Vertical

Horizontal five-axis machines are normally equipped with an automatic pallet changer (APC) ready to be installed on the shop floor. If you’re machining aerospace components that have deep pockets or waffling designed to reduce finished-part weight, the high volume of chips will naturally drop into the conveyor. In addition, horizontal five-axis machines tend to be heavier and more rigid, which helps when cutting steel and titanium.

 

In contrast, vertical five-axis machines tend to be more agile for processing smaller parts. VMCs tend to enable better operator access and can often take heavier cuts, but clearing chips can be inconvenient. High-pressure, through-the-spindle coolant delivery comes in handy to remedy chip accumulation.

 

Swiveling-Head or Trunnion Style

There are pros and cons to different types of machine designs. If you’re loading heavy parts, the non-tilting table on a swiveling-head machine is often preferred, because this type of table offers greater rigidity for holding big, heavy parts. The swiveling head enables the use of shorter, standard tooling, because all tool rotations occur above the part. Swiveling-head machines tend to be more versatile, lending themselves to using multiple fixtures, vises or tombstones. This somewhat simulates the appeal of an HMC.

 

A trunnion-style machine is often preferred in moldmaking, because both rotary axes are contained in the trunnion table itself and the spindle head is stationary. This configuration is similar to that of the three- or four-axis machines most moldmakers are already used to. The spindle head reaches out over the tilting table, providing better undercut capabilities and some access to the underside of the part. As the spindle head itself does not rotate, trunnion-style machines tend to be more effective in heavy chip removal and can use full X, Y and Z travels to accommodate large parts.

EDM 101: What is EDM and Where to Find CNC Drilling EDM Machines Manufacturer?

Posted on by

What is EDM?

 

EDM stands for electrical discharge machining, the applications best suited for this metal removal process are those characterized by extremely exacting tolerances and situations that would be extremely difficult or impossible to handle with any other method of machining.

 

Growth of EDM

 

EDM has rapidly earned its place alongside milling and grinding equipment as a proactive, mainstream technology. EDM is best known for its ability to machine complex shapes in very hard metals. The most common use of EDM is machining dies, tools and molds made of hardened steel, tungsten carbide, high-speed steel and other workpiece materials that are difficult to machine by “traditional” methods.

 

The process has also solved a number of problems related to the machining of “exotic” materials such as Hastelloy, Nitralloy, Waspaloy and Nimonic, which are used on a large scale in the aeronautical and aerospace industries.

 

With the reduction in electrode wear and increased sophistication of EDM controls in rams, new EDM processes use simple-shaped electrodes to 3D mill complex shapes. EDM also is being used for polishing small, intricate surfaces.

 

Since EDM does not involve workpiece/tool forces like a mill or grinder, it is possible to EDM shapes that would break conventional cutting tools or be broken by them.

 

Different Types of EDM

 

  1. RAM EDM

RAM EDM, also known as plunge EDM or standard EDM, is the oldest form of EDM machining. It generally consists of an electrode usually made out of graphite that is plunged into a workpiece in order to create a blind-shaped cavity. It can also be used to generate through holes and geometry but these are not the primary uses of the process.

 

  1. Drill EDM

Drill EDM uses rotating concentric electrodes to drill through a workpiece and basically performs the same functions as a drill press, except that the material hardness is not a factor and the accuracy of the finished hole is far superior than what any drill press can produce. It is best used to drill start holes for the wire EDM in already hardened material as well as accurate very small holes for industries like aerospace and medical equipment.

 

  1. Wire EDM

Wire EDM uses a traveling wire electrode (usually .010” diameter or smaller) that goes through the workpiece. The wire, in this case, is controlled by computer following the assigned geometry for the part to be produced.

 

EDM for Tooling Applications

 

When a part requires special / unique conventional cutting tools, electrodes are easy to machine, unlike carbide. Equally important, the wire used by a wire EDM is available as a standard, off-the-shelf component. EDM is a low cost tooling option when you need short run stamping (less than 5,000 pieces) and low volume broaching. With EDM, there’s no need to make a die set. That’s why EDM is used to make sewing machine components and prototypes. Instead of using expensive broaches, EDM is a very attractive form of low-cost tooling. This is a reason companies use EDM to produce splines and gear teeth along with all their metal stamping & mold making needs.

 

Where to Find The Reliable EDM Machines Manufacturer?

 

About this question, I recommend that you can try to visit the website of OCEAN Technologies Co., Ltd.. This company is specializing in kinds of high quality EDM machines. If you need more information about CNC drilling EDM machines, please do not hesitate to check out OCEAN product pages and feel free to send inquiry to them.

Benefits of Having a Precision Lathe

Posted on by

For complex parts and components, you will always need professional precision CNC machining services. However, for prototypes, simple parts, and short runs, there are also benefits of owning a high precision lathe. Although the machine is automated, it gets its instructions from a human who enters written code. Therefore, to own a machine, you also need an operator qualified to provide it with instructions.

 

CNC machine programming may not be rocket science, but it does require knowledge and skill. However, being in control is the greatest benefit of owning a machine. You have the opportunity to produce what you need whenever you need it. Whether creating a protocol or processing a large run, you have full control. Just remember that there is a financial investment in buying a CNC machine. With many different types of the CNC machine, you can always purchase the one that you would use most and then hire a manufacturer for the other work.

 

Types of CNC Machines

 

Following are the five types of machines most commonly used, although there are others. As you can see, each machine offers distinct benefits.

 

  • Router – A CNC router works by engraving plastic, wood, or metal. Following the entered code, a router can perform simple and detailed engraving tasks.
  • CNC Laser – One of the more advanced types of machine, the CNC laser is similar to a cutter with the exception that it cuts wood and metal. In some instances, this machine also cuts plastic. Regardless of the material, the finished product is perfect.
  • CNC Milling – Widely used, the CNC milling machine moves cutters as well as other tools for cutting metal pieces into specified shapes and sizes. Based on the number of axes that a milling machine has, it falls under several classifications.
  • CNC Lathe Machines – These machines are extremely accurate, but also precise, easy to operate, and capable of producing repeatable parts and components. With CNC lathe machines, you can make 3D molds and shapes out of wood, plastic, and metal.
  • CNC Plasma Cutters – While similar to a CNC router, a plasma cutter setup is not as challenging. With this machine, you can produce 2D molds and shapes out of metal.

The Best Impact Wrench Buying Guide

Posted on by

An impact wrench is a must-have in the garage, but now it’s a must at home and inside the trunk of your car, so we offer for your convenience our very own 8-Step Impact Wrench Buying Guide.

 

A cordless impact wrench is both highly effective and efficient in removing and tightening bolts or screws that feel stuck in place. Having one is necessary in ensuring work is done both safely and swiftly.

 

Injury, however, could occur while using manual tools, the wrong tools, or simply old tools. Mishandling the tools or applications themselves can and do cause complications for the user, not the least of which are injuries, damage to property and machinery, and time that cannot be regained.

 

Acquiring and sticking to automatic and powerful tools like impact wrenches has become no less than necessary for both the professional and amateur alike. In order to help you better determine how best to make your cordless impact wrench purchase, below are some important tips for you to consider before blowing your money on a piece of hardware you will surely come to need around often—and thank your lucky stars for purchasing.

 

  1. High Torque

Simply put, this “power” is the bread and butter of any impact wrench, cordless, corded, or otherwise. Torque is defined by Hyper Physics as “the influence which tends to change the rotational movement of an object.” As it relates to the impact drill, the higher the amount of torque the tool has, the stronger the influence it will exert over the bolt or nut you have it working on.

 

Torque is typically in counted the hundreds. Make absolutely sure that it is not too low, which would only be good enough for intermediate purposes at best. No less than 200 or above is a good number to work with. Anything below is unacceptable! Remember what you want and will use this tool for—this is surely an area where you cannot skimp.

 

Life’s fast pace and development of technology can and does often require higher numbers, but these are not hard to stay abreast of because of the internet. You can easily stay updated by searching for this online – also, keep in mind that alternatives are always easy to find if you eventually think your main wrench falls below the standards that you need.

 

  1. High Rotations Per Minute (RPM)

When selecting an impact wrench that has impressive RPM’s, you will discover that 3,000 or above is an ideal number for basically any impact wrench. The impact tool relies on rotations to tighten or unwind a screw or nut in its place. More rotations translate to, of course, less effort on the part of the operator, as the cordless impact takes on the extra work speed itself.

 

Lower RPM can delay project completion so select a power tool that prioritizes RPM very much, even if the torque or Impacts Per Minute (IPM) may fall a bit below standard. The only exception to this, of course, is if you are simply not as concerned about finishing a task or project quickly.

 

Still, the faster the output shaft spins, the quicker your work can be done. While shopping in your favorite store or online retailer, remember to check the RPM ratings on the product before clicking the buy or reserve button in order to know just how fast your soon-to-be new impact wrench operates.

 

  1. High IPM

IPM (Impacts Per Minute), like RPM, should be suitably high enough because this power tool requires a LOT of contact to push down a screw or bolt and tighten or lose it. If it is not possible on your budget to have a high IPM impact tool, look for a device that balances the torque, RPM and IPM well.

 

The last (IPM) can fall off a bit if the first two (RPM and Torque) are great. Having more IPM means there is more contact between the tool and the intended target, and more contact means the targeted screw or lug nut stays firmly in position. It’s easy to see why this part of the tool is highly important, as well.

 

Couple this with a high torque and RPM and you have the makings of a nearly perfect impact wrench.

 

The next question would naturally be what source of power will your impact wrench use and how much are you willing to spend on it?

 

  1. Great Brand

Like most products out there, an excellent company or manufacturer will get you a lot when it comes to quality of the wrench you ultimately decide to buy and put to use.

 

Veteran brands, due to their established success, have all the privileges and experience to experiment on various designs and updates. Make sure you look into the catalogs of various companies first, in order to have a clear idea on what to buy for your garage or car.

 

New brands do come along here and there, of course, but with a still developing and improving technology like cordless impact wrenches, for example, it would be wiser to trust a brand that has been around for a long time. A tried and tested company would do you a lot of good when it comes to scanning for a potential impact wrench. Look up these trusted, veteran companies first and then check out what impact tool options they offer.

 

  1. Lightweight

Impact wrenches should be light enough for extended use and ease in carrying. If you haven’t picked up an impact or have only used a small variety of corded impacts, then you may actually find yourself surprised (and potentially dismayed) when your new battery-laden impact beast is plopped down at your front door and you lift the box. The good news is that there are many lighter-weight contenders out there that can fit both your application and comfort level simultaneously.

 

Lighter is always better if you are using the tool to screw in nuts and bolts with force. A lightweight tool is much better because it gives more mobility for the user and makes operating the power tool easier. This is especially true for those times when the impact is needed for a difficult project or for longer periods of time.

 

Lightweight wrenches must be prioritized since they make overall use easier and less strain on the wrist while operating on heavy work. Lighter is definitely better for a tool that will used for long periods of time.

 

It’s worth noting here that too many people have permanently damaged their wrists and hands and for no good reason, apart from making a few dollars. This is sad considering how many tools there are available to keep this very thing from happening. A lightweight tool is an excellent way to insure our bodies stay healthy and injury-free.

 

  1. Type of Impact Wrench

Depending on who you are, what you need, want, or think you need or want can vary. Not long ago, the only viable options for impact wrenches were electrical, corded versions, and the more popular compressed air versions. Due to the amazing work done by today’s leading tool manufacturers however, that has changed dramatically and now we have the wonderful option of the portable cordless impact wrench as well.

 

There are other options for the heavy-duty, industrial market of course, but they are outside the scope of this article so we won’t be covering them here.

 

  • Wired Electrical Impact Wrenches

These are 100% dependent upon having—and reaching—an AC outlet, therefore they are not given to situations that would require portability in or to remote locations. However, in certain situations and for certain people, they can keep the costs low and do what needs to be done.

 

They are typically ideal for those who do not need an impact quite as often, or perhaps those who are more like hobbyists, tinkerers, or light-duty, occasional home mechanics. In most cases, they are not as strong in the torque department as the compressed air wrenches, but they do provide enough power for the sporadic user.

 

Another added benefit of the electrical impact is that it doesn’t require the power source to be localized (on the tool itself) and therefore this makes the wrench a bit handier in tight spots.

 

  • Compressed Air Impact Wrenches

These impacts have been around since the dawn of time—or so it seems—and for good reasons.

 

Air tools have some excellent benefits and offer a wide variety of applications, provided one has a source of air provided nearby. While it may not be convenient for most people to lug around a small air tank in the trunk, it is still quite possible to keep one handy in the case of other needs as well, such as airing up a flattened tire on the roadside or perhaps an air mattress at the campsite.

 

The main benefits of the air impact are weight, power, and variety. This version of the impact needs relatively little local parts or mechanisms; therefore the design lends itself to many sizes and applications. “Inline air impact wrench” and “Pistol” impact designs vary, with the former appearing more like a screwdriver-style grip, while the latter should obviously conjure up images of the Wild West.

 

Similar to the electrical impact wrench, the compressed air version draws its power from elsewhere, allowing the tool’s design to focus only on performance and take up less room. This is especially true for the inline versions, which can be quite small—a great design for particular needs.

 

While the compressed air impact wrenches are more portable than their electrical brothers, they still fall short of the mark offered by the latest and increasingly popular member of the family.

 

  • Battery-Powered Cordless Impact Wrenches

In their early years, the battery-powered impact struggled in more than one category. The torque wasn’t yet there, the battery use time seemed shorter than the charge time (not to mention the battery life of the NiCads—shiver), and the prices were great for spitting out whatever you were drinking at the time of observation.

 

However, as they say, “Times they are a’ changin,” and the cordless impact wrench is one of the most useful, practical, valuable, and affordable innovations we have on the earth today.

 

Torque is no longer a problem as these tools come in an array of options for virtually any application, including the everyday, professional mechanic. Using our impact wrench buying guide’s sections above on features, you can choose which specifications are right for you. The same rings true for IPM, so the only remaining issues to consider are size, portability, and weight.

 

In way of size, one might think or suggest that this is where the cordless falls short of the electrical and air impacts, but this isn’t always the case. Years of innovations and advancements in both design and power source cause these cordless tools to be much more similar in size to their predecessors than before. Again, depending on application, we can choose the best impact wrench to suit our needs. Because of today’s technological advancements, we now have cordless impact wrenches that are strong, lighter, and easy to use. The added benefit is that today’s cordless tools are utilizing the Li-Ion (Lithium-Ion) batteries, which offer a compact size with power, use life, and longer lifespan.

 

Now that the cordless impact has gained so much ground on the traditional impacts in these other areas, it has become an essential part of our tool kits and even trunks, primarily due to the fact that they are the kings of portability. Toss it in the truck or car and go—no need to worry yourself or injure your body with large, unruly tools anymore. This is the main asset of the cordless tool: take it anywhere and do what you need to do.

 

  1. Safety Features

So, now you know that it is great to have an impact wrench that has high RPMs and IPMs for the best performance.

 

But in the midst of your starry-eyed shopping, don’t forget to select an impact wrench that is stocked up on the most important features of all: safety. An impact wrench is, after all, a power tool, therefore proper attention must be placed in not only knowing how to use it and what it does, but also what it is capable of.

 

A couple of important safety features include anti-overloading, cooling, etc. The best features on tools are designed for the explicit reason to keep us from sustaining injuries—these included safety mechanisms can save your life and improve the overall life of the tool.

 

Professional or not, these features are important because your safety should always be at the top of the list. The best in every field know that once you get this right, the other features can follow.
