I bought this on a whim when I walked by it at my neighborhood Denver Walmart. I am a professional mechanic, and this tool has been perfect for light to heavy workload. Using it in a shop where I need it for at least ten cars a day, It works great for every task, especially taking lug nuts off of wheels. I did break it within a year, however, which is Campbell Hausfeld's factory warranty, and I contacted them and I got a completely free replacement, and really great service in the process. No, it's not the absolute best impact wrench, but it is worth much more than the price, as I have had many other brands for way too much money, and this one beats all of them that were worth even up to 300 bucks. Above all, the service and the warranty were the best parts of my experience, and I highly recommend it.
It’s not all about power. While power and performance play into our formula, we also take into account value, ergonomics, features, and more. In the end, our charts, in-use photography, and videos should validate the objective results that determine the outcome. Okay, we know our audience, and we know what you want. We’ll keep from dilly-dallying any longer, and we’ll start with the knockout punch, right out of the gate.
The Milwaukee 2763-22 M18 is one of the best designs on the market today in terms of powerful and capable tools, which is why it made our cut for premium choice. The device is capable of generating an impressive 700 ft-lbs of maximum fastening torque and up to 1100 ft-lbs of nut busting torque. It makes innovative design and simplicity merge in a beautiful combination with the thoughtfulness put forth by the manufacturers and helps to make socket changes easier with its ½ inch anvil.
In operation, a rotating mass is accelerated by the motor, storing energy, then suddenly connected to the output shaft (the anvil), creating a high-torque impact. The hammer mechanism is designed such that after delivering the impact, the hammer is again allowed to spin freely, and does not stay 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.) The hammer design requires a certain minimum torque before the hammer is allowed to spin separately from the anvil, causing the tool to stop hammering and instead smoothly drive the fastener if only low torque is needed, rapidly installing/removing the fastener.
L wrench Allen key A wrench used to turn screw or bolt heads designed with a hexagonal socket (recess) to receive the wrench. The wrenches come in two common forms: L-shaped and T-handles. The L-shaped wrenches are formed from hexagonal wire stock, while the T-handles are the same hex wire stock with a metal or plastic handle attached to the end. There are also indexable-driver-bits that can be used in indexable screwdrivers. keys
Leading the pack in driving the weight up the scale is the Milwaukee 2767 (Gen 2) cordless impact wrench. While all the others can’t max the scale with 50-pounds atop, the 2767 can. In fact, we had to add 10 more pounds, a total of 60, and the Milwaukee 2767 still drove it the majority of the way. DeWALT and the Ingersoll Rand followed a pretty close second at 94% and 92% of the Milwaukee in the power category.

Compressed air is the most common power source for impact wrenches, providing a low-cost design with the best power-to-weight ratio. 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 drive the hammer directly from the motor, giving it fast action when the fastener requires only low torque. Other designs use a gear reduction system before the hammer mechanism, most often a single-stage planetary gearset usually with a heavier hammer, delivering a more constant speed and higher "spin" torque. Electric impact wrenches are available, either mains powered, or for automotive use, 12-volt, 18-volt or 24-volt DC-powered. Recently, cordless electric impact wrenches have become common, although typically their power outputs are significantly lower than corded electric or air-powered equivalents. Some industrial tools are hydraulically powered, using high-speed hydraulic motors, and are used in some heavy equipment repair shops, large construction sites, and other areas where a suitable hydraulic supply is available. Hydraulic impact wrenches have the advantage of high power-to-weight ratio.
