9057-6 Cordless Impact Driver Review
This cordless impact driver from Milwaukee comes with two batteries
This was the heaviest of the nine cordless impact drivers we tested, but its performance was disappointing. It has the slowest motor and the least amount of torque of the 12v tools we tested, though its impacts per minute are nearly the same. Consequently, it drove the least amount of screws. It comes as a 3/8-in. square drive with a 1/4-in. hex-head adapter.
