The Milwaukee 2564-20 is a cordless 3/8-inch right angle impact wrench built on the M12 FUEL brushless platform. Its 2.2-inch head fits where pistol-grip impacts cannot, and it delivers up to 220 ft-lbs of nut-busting torque with no kickback. The 4-Mode Drive Control adds precision: three RPM/IPM settings plus Auto Shut-off forward and Bolt Removal Mode reverse. It suits mechanics and installers working in tight engine bays, under dashes and on assemblies; against pistol-grip 3/8 impacts it trades raw speed for access and control, and owners rate its torque and reach highly.

Rated 4.7 out of 5 across 496 ratings, owners praise the reach and torque for its size and the control modes. Complaints center on it being slower than a pistol-grip impact and on the bare-tool setup.
The M12 FUEL 3/8" right angle impact wrench is a cordless tool with a friction ring anvil. It delivers up to 220 ft-lbs of torque without kickback for removing stubborn bolts and fasteners. The tool is sold bare, without a battery.
Its head is only 2.2" high, so it fits into tighter spaces than a pistol-grip impact wrench. That can reduce the need for socket extensions.
The 4-Mode Drive Control adjusts the fastening and bolt removal behavior. Modes 1-3 offer RPM and IPM adjustments. Mode 4 has Auto Shut-off in forward, which applies no more than 15 ft-lbs of torque to prevent over-tightening. In reverse, Mode 4 is a Bolt Removal Mode that slows the RPMs sharply once the bolt is loose. REDLINK PLUS Intelligence protects against overloads, overheating and over-discharge.
