This M7 NC-4256Q Impact Wrench from Mighty Seven has 1,000 ft./lbs. of torque. All this power is coming from just a 1/2″ air impact wrench. That is enough power for removing the most stubborn of bolts. It weighs in at only 4.0 lbs. and is less than six inches long. This is like having a heavy weight champ in the body of a lightweight.

M7 NC-4256Q Impact Wrench NC-4256Q Features

I was most impressed with the power of this impact, coming in such a small package. Even though I was not able to test whether or not the NC-4256Q actually has 1,000 ft/lbs of torque, I was able to give it a good workout on several projects in and around different shops. From lug-nuts on a heavy duty truck to lug-nuts on an Olds 442, and even crankshaft bolts, the M7 impact never even flinched. This NC-4256Q delivered all the power needed in every situation.

In addition to the power, the M7 NC-4256Q proved to be quite comfortable to hold and use. The handle has a soft rubber cover that wraps the high-impact plastic. Not only does it provide comfort, it also reduces vibration and is oil resistant. Exhaust from the M7 flows out the bottom of the handle, keeping it away from the user. The sound seems to be much less than my typical go-to impact wrench.
