We love the DEWALT DCF880HM2 for its simple yet easy to use design and ability to make work easier. It comes with an impressive energy efficiency system that allows you to have 33% more charge than other standard battery packs are capable of attaining. This translates into about 24 hours of work time that you’ll be able to use before the batteries need to be recharged again. You’ll also be able to take advantage of the hog ring anvil incorporated into the design. It makes it easier to do socket changes and get on to other work.
The Milwaukee 2763 has very few notable faults. One issue is that the work light LED is just under the front of the impact. Commonly, users will use their other hand to brace the front of the impact, this will block the LED so it’s nearly useless. The 2763 delivers great power, and it did well in our speed test as well. Milwaukee sets itself apart with the 5-year warranty, and you can buy it online, your tool store, or in the big box stores.
There are many reviews and head-to-head impact wrench tests that already exist. Most of these tests include the Skidmore Wilhelm torque testing equipment. By turning a large nut, you raise the needle on the PSI gauge. Then, dividing by a factor provides a “torque” number. While these tests do a great job at validating (or not) manufacturer calculated numbers, we felt there were better ways to demonstrate raw power. In short, we weren’t satisfied with doing the same ol’ same.

Cordless impact wrenches come in two body styles: inline and pistol-grip. The inline style of impact wrench looks a lot like a large screwdriver, with a grip behind the hammer and anvil. The pistol style is shaped like a handgun, and the grip rests underneath the motor. Cordless impact wrenches also feature a selection of socket sizes designed to fit nuts and bolts of different sizes. The following table shows what socket sizes work with each impact wrench shape. Inline wrenches work best for jobs where you’re working in tight spaces and simply can’t fit a pistol-type impact wrench. If you plan to work on machinery, especially cars, then an inline impact wrench is a must-have tool.
The hammer mechanism in an impact wrench needs to allow the hammer to spin freely, impact the anvil, then release and spin freely again. Many designs are used to accomplish this task, all with some drawbacks. Depending on the design, the hammer may drive the anvil either once or twice per revolution (where a revolution is the difference between the hammer and the anvil), with some designs delivering faster, weaker blows twice per revolution, or slower, more powerful ones only once per revolution.

Our rig combines the front wheel of a car/truck with a weighted sled like those typically seen at tractor-pulls. Although our STR TorQ-O-Matic 5000 testing rig results may not provide a number you can brag about, it does a great job at providing work that levels the playing field on these high torque cordless impact wrenches. As the impact wrench turns the rotor, the weight moves further up the ramp, providing more clamping force on the rotor via the caliper.

When choosing your new cordless impact wrench, there are a few things you should consider. The first thing to decide is the brand. If you have other cordless tools, it’s a good idea to choose a cordless impact wrench that uses the same battery pack and charger as your other devices. It’s also a good idea to spend a little time doing a cordless impact wrench comparison. Some of the high-end models offer additional features such as adjustable torque settings, which cuts out the need to use a manual torque wrench.

crow's-foot wrench crow's foot A type of wrench designed to use the same drive sizes as socket wrenches, but non-cylindrical in shape. The ends are the same as those found on the open-end, box-end, or the flare-nut wrenches. These wrenches are used when torque must be measured, or when the application precludes the use of a regular socket or wrench. Also used in place of conventional open/box wrenches where the wrenches are large, usually at a lower cost, or for when space and weight restrictions are critical. socket

If someone or something throws a wrench into the works or throws a monkey wrench into the works, they cause problems which prevent something from happening in the way that was planned. Of course they may not sign the agreement by the sixteenth and that would throw a monkey wrench into the works. Note: Instead of saying the works, people often describe the situation in which the problem is caused. Most health-related problems, of course, are not life-threatening, but they can throw a wrench into an otherwise pleasant holiday. The US delegation threw a giant monkey wrench into the process this week by raising all sorts of petty objections. Note: The usual British expression is throw a spanner in the works.
