speed brace A crank-shaped handle that drives a socket. The socket-driving analog of the brace used to drive a drill bit. Used instead of a ratchet in a few contexts when it can save substantial time and effort—that is, when there is a lot of turning to be done (many fasteners), ample room to swing the handle, ample access to the fastener heads, etc. Has less leverage than a conventional ratchet wrench. Used occasionally in automotive repair or job shop work. socket

While pistol impact wrenches are bulkier, their grip style is more ergonomic to prevent strain on your hands, which in turn allows you to work for longer periods without fatigue. Some of these models can equip side handles which let you use your weight for greater leverage and to maintain a proper working angle. If you don’t need the special fit of an inline wrench, a pistol-style impact wrench is usually the ideal choice.


crow's-foot spanner A wrench that is used for gripping the nuts on the ends of tubes. It is similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening just wide enough to allow the wrench to fit over the tube, and thick jaws to increase the contact area with the nut. This allows for maximum contact on plumbing nuts, which are typically softer metals and therefore more prone to damage from open-ended wrenches. common

The ability to remove lug nuts is largely dependent on how powerful your tool actually is. However, the answer is yes, you should be able to remove a lug nut using one of these tools. In order to remove a lug nut, most lug nuts will need to be removed with at least 100 ft-lbs of torque. This is equivalent to 1200 in-lbs should you need an inch conversion instead of a foot conversion. We know that will take at least 100 ft-lbs of torque to remove the lug nut because that is about what it takes to put a lug nut into place.
When compared to many other power tools, cordless impact wrenches are quite specialized in what they do. Large nuts and bolts may not need to be removed or tightened as often as smaller screws. But when you do need to adjust one, a cordless impact wrench will save you both time and energy. They can also loosen and tighten nuts and bolts much more accurately than hand tools such as sockets and ratchets, which is critical when it comes to working with larger bolts or on machinery.

When it comes to the Makita XWT08, you can’t go wrong with this purchase. While it finished sixth with 78.7 points, only nine points separated 2nd to 6th. If you are Makita fan, then you’ll be proud to own the XWT08 as well. Power is ample, and it finished 2nd in real-world testing, with the repetitive power (speed) I-beam test, running off all 10 nuts in just 12.6 seconds.


If you find yourself working with automotive equipment (click here for cordless impact drivers or see these brushless impact drivers) or on mechanical based projects quite often, you likely know the benefits of having the best cordless impact wrench available on today’s market. Having such a pristine tool helps to make work an easier process and allows you to go about your day to day tasks with ease. You’ve probably been at the point in life before where you’ve had to settle for tools that were second best.

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.[2] 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.
Great comparison test, better than the others I read online. I ended up buying the first gen Milwaukee, which is still a great gun. I used a co-workers and was impressed pulling lug nuts off a one-ton dump truck. I was able to get the gun, hard case, set of Milwaukee-branded impact sockets, two 5.0Ah batteries, the charger, gun nose protection boot, and Milwaukee LED worklight for $450. Too good a deal to pass up.
Cordless power tools (including impacts) are the becoming more and more common. They’re especially popular with racers. The reason being, most racecar trailers aren’t equipped to handle a high-horsepower, two-stage compressor. That means the generator most racers have can be used to keep tabs on the battery charger(s) for these electric tools. Torque output of the tool is important, but because the battery is the heart of what powers any cordless tool, picking the type of battery technology that the tool uses is critical.
Automotive repair shops each have their own unique selection of tools, but almost all have one tool in common: the impact wrench. An impact wrench, which may also be called an air gun, air wrench, or torque gun, is a power tool that puts a high-torque output in the palm of your hand, without much work on your part. Rather than tightening a bolt by hand, which would not give you enough torque to ensure it was completely tight and safe, you can use an impact wrench to torque it and ensure it is tight. The wrenches have a socket wrench design, which is often used to repair automobiles and other heavy equipment. It can also be used in construction projects or product assembly when the products are large and heavy.
A common hammer design has the hammer able to slide and rotate on a shaft, with a spring holding it in the downwards position. Between the hammer and the driving shaft is a steel ball on a ramp, such that if the input shaft rotates ahead of the hammer with enough torque, the spring is compressed and the hammer is slid backwards. On the bottom of the hammer, and the top of the anvil, are dog teeth, designed for high impacts. When the tool is used, the hammer rotates until its dog teeth contact the teeth on the anvil, stopping the hammer from rotating. The input shaft continues to turn, causing the ramp to lift the steel ball, lifting the hammer assembly until the dog teeth no longer engage the anvil, and the hammer is free to spin again. The hammer then springs forward to the bottom of the ball ramp, and is accelerated by the input shaft, until the dog teeth contact the anvil again, delivering the impact. The process then repeats, delivering blows every time the teeth meet, almost always twice per revolution. If the output has little load on it, such as when spinning a loose nut on a bolt, the torque will never be high enough to cause the ball to compress the spring, and the input will smoothly drive the output. This design has the advantage of small size and simplicity, but energy is wasted moving the entire hammer back and forth, and delivering multiple blows per revolution gives less time for the hammer to accelerate. This design is often seen after a gear reduction, compensating for the lack of acceleration time by delivering more torque at a lower speed.
