The Milwaukee M18 1/2" Impact Wrench is a powerful and compact tool designed for versatility and efficiency. It features a 4-Mode DRIVE CONTROL system, allowing users to select between four different speed and torque settings for various applications. Its extremely compact design, measuring only 124mm, provides excellent access in tight spaces. The impact wrench offers a bolt removal control that decreases RPMs once a bolt is loosened to prevent fastener drops, and an auto shut-off control that limits torque to 34 Nm for hand-tightening to prevent over-tightening. Tri-LEDs enhance workspace visibility. This tool is part of the Milwaukee M18 FUEL™ series, utilizing a POWERSTATE™ brushless motor and REDLINK PLUS™ electronic intelligence for superior power, run time, and durability. It delivers 339Nm of nut-busting torque. Requires an M18 battery (not included). Includes a 1/2" square friction ring for secure accessory attachment and a reversible belt hook. It is compatible with all Milwaukee M18™ batteries.
