The Milwaukee Fuel High Torque Impact Wrench view at Home Depot is one of the most powerful impact wrenches for its size; it makes quick work of even the toughest nuts and bolts, letting you loosen or tighten them with ease. There are three basic types of impact wrenches: those powered by air, AC current, or batteries. These tools are very powerful, lightweight, and generally less expensive than electric impact wrenches, but require an air compressor to work and are generally more tool than required outside of a professional auto shop.

Corded impact wrenches are next in line when it comes to power, but tether you to the closest electrical outlet.

Cordless impact wrenches are the most popular type for homeowners, DIYers, and those who do car repair as a hobby. On the plus side, these tools give you the utmost in freedom to use them wherever needed.

Some manufacturers state the torque in foot-pounds of force, while others use inch-pounds. But for most people not working in professional auto shops, a tool towards the lower end of that range is more than sufficient, while a tool in the mid-range is suited for most automotive work. The rate at which an impact driver spins is measured in revolutions per minute. As a rough guideline, most cordless impact wrenches have maximum speeds of anywhere between 1, and 3, rpm, with the middle of that range being average.

Some impact drivers have variable speed controls so you can choose from two or three different settings depending on your needs. As a general rule, most cordless impact wrenches deliver anywhere from 2, to 3, impacts per minute. These powerful tools are used to turn nuts and similar fasteners with far more force and speed than could be delivered by hand or with a traditional wrench.

It only took slightly longer when we removed rusty bolts on a farm implement. We also drove six-inch lag bolts into pressure treated lumber. We found the three speeds were most useful when trying to avoid over-tightening fasteners. We were also able to break free large, rusty nuts on our old farm implement.

This impact wrench has four mode settings. The fourth mode, Drive Control, is the one we really like, though. When driving, it limits torque to 35 feet-pounds, so there is no risk of over-tightening fasteners. When removing a fastener, it starts off at full torque, then backs off the RPMs when the fastener has broken loose, preventing spinning off at full speed and sending the fastener pinwheeling away.

The compact body and three LEDs on the face of the tool make it a good option in tight, dark spaces.

This is a professional-grade tool, designed to stand up to daily use, but also an option for homeowners with frequent projects. Through the middle of the square, half-inch impact drive is a quarter-inch, quick-change hex-shank holder—use it with impact sockets or hex driver bits.

With three RPM settings, it makes quite a versatile tool, good for a wide variety of fastening and mechanical jobs. On paper, the Freak appears to be lacking with only foot-pounds of torque, but it produces more than 4, impacts per minute, the highest number in this test at up to 3, RPM.

It also had no trouble with rusted bolts on the old cultivator we brought in for the test. One last thing worth noting is that Bosch offers an optional Connectivity Tool Module that enables customized tool settings via Bluetooth and a connected app. We were able to break loose large, rusty nut and bolts on an old piece of farm equipment, as well as remove lug nuts on the F farm truck.

We also drove some lag bolts into pressure-treated lumber. High-torque impact wrenches tend to weigh more because they have beefier components required to handle the forces involved in transferring all that torque. This is no exception and weighs 7. Removing the lug nuts on the F Super Duty we brought in was seemingly effortless, the Max XR breaking them free in a fraction of a second.

We tried it in all three speed settings, with the highest removing them the fastest. Working on the rusty farm implement felt like a perfect job for the Max XR. The rusted nuts and bolts were no match for it—the only issue was being able to reach a couple of them because of the size of the wrench. Makita engineers succeeded in packing a lot of power and features into this ultra-compact wrench, making it the ideal tool when working in tight spaces. We also love its dual LED work lights and super-efficient brushless motor.

The tool accumulates energy by the hammer cage over one or more revolutions and once the hammer hits the output shaft anvil , it creates the tightening or untightening torque. The design of the tool can play a key role in improving productivity. For example, a well-positioned center of gravity is a great benefit, as it enables better support over extended periods, while different handle shapes and trigger positionings can improve user comfort.

The material of the tool is another critical consideration. Metallic tools are usually more robust, but also heavy to use over long periods. Composite tools, on the other hand, are much lighter, enabling better maneuverability, but the material has made them less durable.

Fortunately, advancements in material development over the last decade have improved the mechanical resistance of composite, improving its strength and making it a good alternative to metal in many applications. It is good to remember that the clutch housing and the body of the tool can be made of different materials. When you compare tools, make sure you check which part is composite and which is metal.

Always choose a tool with a maximum torque that is superior to the torque needed for your application. This will reduce the time you spend using the tool and the vibrations you are subjected to. Beware of overtightening! In some applications, for example when changing tires in small vehicles or trucks, tightening requires precision and torque control. Using tools with torque limited functions, coupled with a torque wrench, will optimize the application without overtightening and damaging the studs.

You can identify the ideal tool square by looking at the size of the thread. If the square is too small compared to the thread, it will not be suitable and is likely to break. However, if the square is too large, it will be too strong and break the screw when tightening it. It is vital to pay attention to factors that affect user safety and ergonomics, such as the sound level and vibration. The sound level is usually governed by the ISO standard and the lower the value, the safer the user experience.

The same goes for vibration levels, usually governed by ISO lower vibration levels equal a safer and more comfortable user experience. Some impact systems are designed to enable low vibration levels and safety and comfort can also be further enhanced with the use of vibration-absorbing gloves. By considering these seven points you will improve safety associated with using tools in the workplace, therefore protecting operators.

An additional benefit to these responsible practices is that you will improve efficiency too! Noise and vibration levels are factors to consider when choosing the tool to use for your application. Knowing what you need to consider when looking for the right impact wrench for your application is a good start, but sometimes reviewing technical values is not enough to enable a well-informed purchase decision.

To ensure the tool can meet your needs, it is always a good idea to discuss your requirements with the manufacturer and request a trial. Trying the tool out in your target application will give you confidence that it is a good fit for the task, the environment and ultimately, the way you work. Thanks to its relatively low cost and robust composition, steel continues to rival alternative materials in applications where cost-efficiency is more important than achieving the lowest possible weight.

However, with a density of 7. Continue reading. Has your pneumatic impact wrench started to become unreliable, not perform as it should or suddenly stopped working?

One of the most common reasons for lack of durability and premature tool failure is inadequate lubrication — and not just of the motor, This guide provides a brief overview of the technology and outlines some simple steps to help you get starte
