Cordless Impact Wrench Reviews

What is a Cordless Impact Wrench?

An impact wrench based on research is also known as an impactor, air wrench, air gun, rattle gun, torque gun, windy gun is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user which stores energy in a rotating mass, then delivers it suddenly to the output shaft.

Most impact wrench uses compressed air as common power source, although electric or hydraulic power is also used; imagine your impact wrench now cordless which uses electric for power.

Impact wrenches are handy tools and widely used in many industries, such as automotive repair, heavy equipment maintenance, product assembly, major construction projects, and any other instance where a high torque output is needed. Cordless Impact wrenches makes your automotive repair easy breezy. You can use it either for home use or even if you’re a professional.

Impact wrenches are available in every standard socket wrench drive size, from small drive tools for small assembly and disassembly, up to larger square drives for major construction. Below are some of the Best Cordless Impact Wrenches that you can purchase online that have great value for your money.

The Best Cordless Impact Wrench Guide for Buyers


Choosing the Best Cordless Impact Wrench

In your everyday automotive repair, you will rely on a handy tool with great performance. Whether you’re a first time user or a professional mechanic having a powerful torque tool to get the job done is a must because this can improve your time maintenance. When choosing the Best Cordless Impact Wrench you need to consider its parts and components. A great rotating mass is a must because this stores energy which connects it to the output shaft that creates a high torque. You also need to consider the hammer mechanism which is designed as such to deliver the impact and to spin freely to prevent the tool from being locked. With this design, the only reaction force applied to the body of the tool is the motor accelerating the hammer, and thus the operator feels very little torque, even though a very high peak torque is delivered to the socket.

This is similar to a conventional hammer, where the user applies a small constant force to swing the hammer which generates a very large impulse when the hammer strikes an object. Because the hammer spins and has velocity before impacting the anvil, the hammer has momentum. Because it has momentum, it must have kinetic energy.

So whether you just started into automotive repairs to heavy equipment maintenance, having a handy yet powerful tool can make your job faster and easier.

Things to Look for When Buying the Best Cordless Impact Wrench

So you’re going to ask, what are the things that you need to consider or look for when buying the best cordless impact wrench? Well the answer is its components, features and specifications. This includes the power source, effects and impact drive, the hammer mechanism and last but not the least sockets and accessories. You should consider the mentioned features as this will help you in all your repair work either for home or work use.

Now let us start with the power source. The power source is mostly consisting of compressed air for impact wrenches. A simple vane motor is almost always used, usually with four to seven vanes, and various lubrication systems, the most common of which uses oiled air, while others may include special oil passages routed to the parts that need it and a separate, sealed oil system for the hammer assembly. Most impact wrenches drives the hammer directly from the motor, giving it fast action when the fastener requires only low torque.

For the effects and impact drive, A wrench that is capable of freeing a rusted nut on a very large bolt may be incapable of turning a small screw mounted on a spring. That is why “Maximum torque” is the number one most often given by manufacturers to deliver instantaneous peak torque. There’s also the “Working torque” for continually driving a very stiff fastener and the “Nut-busting torque” which can loosen a nut tightened with the specified amount of torque in some specified time period.

Then we go to the hammer mechanism. This is an impact wrench needs to allow the hammer to spin freely then release and spin freely again. Depending on the design, the hammer may drive the anvil either once or twice per revolution with some designs delivering faster, weaker blows twice per revolution, or slower, more powerful ones only once per revolution.

Then lastly the sockets and accessories, as per research sockets and extensions for impact wrenches are made of high tensile metal, as any spring effect will greatly reduce the torque available at the fastener. Even so, the use of multiple extensions, universal joints, and so forth will weaken the impacts, and the operator needs to minimize their use. Using non-impact sockets or accessories with an impact wrench will often result in bending, fracturing, or otherwise damaging the accessory, as most are not capable of withstanding the sudden high torque of an impact tool, and can result in stripping the head on the fastener.

All in all, look for the perfect specification and features of the cordless impact wrench. It should not stress out your wrist or even make funny noises. It should also provide high power torque to get the job done a lot easier and faster.

Common Best Cordless Impact Wrench Sizes and Styles

Impact wrenches are available in all sizes and several styles, depending on the application. You have the 1/4″ drive wrenches which are commonly available in both inline where the user holds the tool like a screwdriver, with the output on the end and pistol grip where the user holds a handle which is at right angles to the output forms. You also have the 3/8″ impacts which are most commonly available in pistol grip form and a special inline form known as a “butterfly” wrench, which has a large flat throttle paddle on the side of the tool which may be tilted to one side or the other to control the direction of rotation, rather than using a separate reversing control, and shaped to allow access into tight areas.

The most popular is the 1/2″ drive units which are virtually available in pistol grip form, with any inline type being virtually impossible to obtain due to the increased torque transmitted back to the user and the greater weight of the tool requiring the larger handle. Then the 3/4″ drive impact wrenches are again essentially only available in pistol grip form. The 1″ drive tools are available in both pistol grip and “D handle” inline, where the back of the tool has an enclosed handle for the user to hold and the 1.25″ and larger wrenches are usually available in “T handle” form, with two large handles on either side of the tool body, allowing for maximum torque to be applied to the user, and giving the best control of the tool.

There are various methods that are used to attach the socket or accessory to the anvil, such as a spring-loaded pin that snaps into a matching hole in the socket, preventing the socket being removed until an object is used to depress the pin, a hog ring which holds the socket by friction or by snapping into indents machined into the socket, and a through-hole, where a pin is inserted completely through the socket and anvil, locking the socket on.

Many users choose to equip their air-powered impact wrenches with a short length of air hose rather than attaching an air fitting directly to the tool. A short length of hose also prevents the air fitting from being broken off in the base of the tool if the user loses their grip and the tool is allowed to spin.
