Impact wrenches are 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. For product assembly, a pulse tool is commonly used, as it features a reactionless tightening while reducing the noise levels the regular impacts suffer from. Pulse tools use oil as a medium to transfer the kinetic energy from the hammer into the anvil. This gives a smoother impulse, a slightly lower torque to weight ratio and a possibility to design a shut off mechanism that shuts the tool down when achieving the correct torque. Pulse tools are not referred to as "impact wrenches" as the performance and technology are not the same.[according to whom?]

This 2767 Gen 2 delivers the power and does it over and over, without a hiccup. Added features, such as the bolt removal mode, set apart the Milwaukee Gen 2 from the rest. Earning 97.6 points from a possible 100, this second generation high torque impact from Milwaukee beat 2nd by more than 11 points. The added LED worklight, shining from the battery area onto the work surface is a nice feature as well. At only $449 and a 5-year warranty, this also makes it the best value as well.
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. Non-impact sockets and accessories are made of a harder more brittle metal. Safety glasses should always be worn when working with impact tools, as the strong impacts can generate high-speed shrapnel if a socket, accessory, or fastener fails.
Two wrenches, both nominal size ​5⁄8 in, with a diagram superimposed to show the logic that allows them both to be labeled the same when their actual sizes are clearly different (across-flats distance vs screw diameter). The larger wrench in this photo is from the 1920s or earlier; its face was polished to allow the size stamp to be visible in the photograph.
Another common design uses a hammer fixed directly onto the input shaft, with a pair of pins acting as clutches. When the hammer rotates past the anvil, a ball ramp pushes the pins outwards against a spring, extending them to where they will hit the anvil and deliver the impact, then release and spring back into the hammer, usually by having the balls "fall off" the other side of the ramp at the instant the hammer hits. Since the ramp need only have one peak around the shaft, and the engagement of the hammer with the anvil is not based on a number of teeth between them, this design allows the hammer to accelerate for a full revolution before contacting the anvil, giving it more time to accelerate and delivering a stronger impact. The disadvantages are that the sliding pins must handle very high impacts, and often cause the early failure of tool.
Look for design enhancements, such as all-metal construction for the gear housing or high-strength plastic overmolds, which helps to prevent damage due to impacts or being dropped. Impact wrenches with brushless motors have fewer moving parts, which means that there’s less of a chance of components breaking down, and maintenance is easier to perform.
clamp ratchet wrench clamp ratchet spanner An open-ended multi-size ratchet wrench. The ratcheting mechanism allows the nut to be clamped-on or loosened with a reciprocating motion; flip the wrench to change direction of the drive. The wrench takes the advantage of the clamp action to allow multiple sizes in both SAE and metric standards. Each wrench typically will allow up to 3 non-metric sizes and 3 metric sizes. adjustable
Many of the points for the Matco Tools impact is lost in the value department, including price and warranty. It was the highest priced of the shootout, by more than $100 ($699 MSRP). It really doesn’t have the features or output to explain the huge price. In addition, the warranty period is only 30 days. Compare this to 5 years with Milwaukee. In the end, the Matco Tools MCL2012HPIWK finished with 70.2 total points.

Grip – Impact wrenches can actually come in a few shapes and sizes, but in this guide we’ve concentrated on models that – if you squint – look like standard power drills. We’ve done this as most cordless style impact wrenches are of this type. They are also simple to use. Because of their shape they do need a good grip, so make sure you bear that in mind. A good grip should be ergonomic, so it’s comfortable to hold, with good trigger placement and a raised or rubberized surface so you can orient the tool in your hand by touch only.

While the DeWALT tied for 2nd for features, it did suffer just a bit in the ergonomics category. With ergonomics being a more subjective testing category, users probably need to put the tool in their hand to make their own decision. If you have other DeWALT tools or you think you’re leaning to the DCF899, it’s easy to yes to this impact wrench. Furthermore, you can find the DeWALT stuff about anywhere tools are sold, making it easy for purchase.

Cordless impact wrenches are a great tool to use regardless – but they’re even better for people who enjoy working freely and without the restriction of a cord, or for people who need to be able to have tools that can travel with them throughout a workday. Cordless impact wrenches help to make work more convenient and an easy without sacrificing on any of the power that the air powered models are able to produce.
When a nut or a bolt head is in a recess below the surface of a bolted member, a socket wrench must be used; this is essentially a short pipe with a square or hexagonal hole and either an integral or a removable handle. Modern socket wrenches are made in sets, consisting of a number of short sockets with a square hole in one end that fits a removable handle and 8- or 12-point holes in the other end to fit various bolt and nut sizes. There are several types of handles and extensions, such as a T handle, screwdriver-grip handle, and a ratchet handle (see ratchet).

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.


With a corded electric impact wrench, you just plug it in and turn it on. Slip on the socket and extension and you’re ready to rock. An electric impact wrench can prove be one of the go-to tools in your shop that allows you to fly through difficult jobs. Just keep in mind that corded electrics won’t have the nut-breaking torque of an air tool. Fair enough.
