Wrenches and applications using wrenches or devices that needed wrenches, such as pipe clamps and suits of armor, have been noted by historians as far back as the 15th century. Adjustable coach wrenches for the odd-sized nuts of wagon wheels were manufactured in England and exported to North America in the late eighteenth and early nineteenth centuries. The mid 19th century began to see patented wrenches which used a screw for narrowing and widening the jaws, including patented monkey wrenches.
The Porter-Cable PCC740B is one of the best tools on the market for contractors and workers who need to be able to quickly and efficiently remove nuts and drive in bolts. The design of the device is expertly done and allows you to hold the machine during extended work periods without tiring out. You’ll be able to appreciate the expert craftsmanship that went into completing this device when you take advantage of the 330 ft-lb torque or 1,650 impacts per minute that you can generate while using this tool. With all the great features, including the ½ inch hog ring, you’ll quickly learn to appreciate this top quality machine.
Remember when we stated there was an exception to the big air power torque? This is it: Ingersoll Rand’s 1/2-inch drive W7150K2 packs a whollop. It has a maximum output rating of 780 foot-pounds and it’s powered by a 20-volt Lithium Ion battery. Part of the secret to it’s big power is the rare earth magnet motor. This isn’t an inexpensive impact wrench, but the kit includes two batteries along with a charger.
Summarizing a shootout always presents a problem. The real bottom line to this best cordless impact wrench shootout seems to hang solidly on power and performance. Milwaukee aimed to hit hard with the release of the 2767 high torque impact back in September. The results show their efforts seemed to have paid off. There’s been a ton of hype over this tool since the Milwaukee Tool NPS17 media event in Milwaukee, WI back in May. We had the privilege of getting our hands on the 2767 back then, and we couldn’t wait to bring it in the shop for testing.
Jobs that require the power of an impact wrench usually entail using them for many operations over an extended period. Ergonomic handle grips and anti-vibration measures help to reduce work-related strain. Additionally, you should pick a cordless impact wrench with just the right amount of power necessary to perform the job properly. A smaller motor tends to mean fewer vibrations, which in turn lessens the physical strain.

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.
However, since most lug nuts tend to sit in their position for quite some time before being removed, there are several things that must be factored into place. The first is that the lug nut could become too cold and freeze. This will affect how much power it takes to get the lug nut out of its place. There is also the chance that your lug nut could be stuck if one of the threads was broken or over-tightened the last time it was serviced.
The Goodyear 24V is a solid device - one of the best on the market. You’ll love the variable speed trigger that allows you to have greater control over what you do. You’ll be able to work safely and efficiently thanks to the measures put in place by Goodyear. The machine is strong, durable, and built to last. It comes with heavy duty gears that are treated for heat and designed to work effectively over prolonged periods of time. The device also comes with a forward and reverse setting, allowing you to quickly tighten or loosen nuts and bolts while you’re on the job and quickly move on to the next task at hand.
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.
