Makita cordless impact wrenches deliver high torque impact power and are designed to fit impact-rated socket sets. They pack plenty of torque for a wide range of fastening and loosening tasks, and are powerful and convenient substitutes for air-powered and AC wrenches. The batteries provide long run time and quick charging for less downtime and increased productivity.
Regardless of the style of cordless impact wrench that you choose, or what its socket size is, the most important feature to consider is how much torque it generates. When performing a cordless impact wrench comparison, look at the maximum torque that each one is capable of creating. Many of the best cordless impact wrenches feature multiple torque settings making them much more versatile than those with only one torque setting. Setting he torque down only to what’s needed lets your battery work longer and prevents overtightening.

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.
As it is, the tool has a very effective 2-position power button. In position 1, the power is limited to 100 lb/ft for when you need accuracy and a gentle touch. Setting 2 unleashes the dogs of war and allows you to crank out the full 700 lb/ft of torque for unrivalled power. There is no rusted or over-tightened bolt on earth that is going to be able to resist that level of power!
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.
If you have the Matco MCL2012HPIWK impact wrench, then you should be proud of it. It won’t leave someone stranded by not doing work. In fact, when using the Matco Tools impact, it felt like it hit the hardest initially when removing a fastener, and this showed in our speed test. It does lack in the total power department, but that’s not the real reason this impact finished in 8th place.
