Milwaukee introduced the first line of Compact Impact Wrenches with the M18 system. With a specially designed impact mechanism, the 2652-22 delivers best in class fastening speed. At only 4.1lbs and 5-3/4", the compact impact wrench is small enough to fit into tight spaces, yet delivers 2200 in-lbs of torque. The M18 Cordless LITHIUM-ION 1/2" Compact Impact Wrench w/Pin Detent has a ½" anvil pin detent for superior socket retention, while a built-in LED light illuminates the work surface. The Milwaukee M18 XC High Capacity RED LITHIUM battery features Digital Power Management with Overload Protection and a Temperature Management System to provide maximum tool life. The 2652-22 is also compatible with the M18 Compact RED LITHIUM Battery (48-11-1815.)
