Milwaukee 2904-20 M18 FUEL™ 1/2" Hammer Drill/Driver

Most Powerful Hammer Drill in its Class. Advanced AutoStop™ Protection. Compact 6.9" Frame Clearance.

The Milwaukee 2904-20 M18 FUEL 1/2" Hammer Drill/Driver introduces unmatched aggregate drilling speed, extreme high-torque hole production, and cutting-edge electronic user safety directly to the core of your industrial tool chest. Purpose-built to conquer heavy commercial installations without forcing you to wrestle long extension cords across your site, this cordless powerhouse unleashes a relentless 1,200 in-lbs of maximum fastening torque and reaches up to 2,000 RPM in high-speed mode. It provides general contractors, mechanical plumbers, electricians, and masonry framing teams with a highly balanced, robust 18V tool optimized to punch cleanly through dense structural timbers, thick steel plates, cinder blocks, and solid concrete headers without standard motor bog-down.

Maximum work production and advanced jobsite safety are engineered into every detail of this fourth-generation M18 FUEL™ flagship tool. Measuring an ultra-compact 6.9 inches in overall length, this drill offers the best access and maneuverability inside tight stud bays, crowded utility lanes, and overhead joist spaces. Driven by a heavy-duty POWERSTATE™ Brushless Motor and monitored by smart REDLINK PLUS™ Electronic Intelligence, it maintains maximum power under extreme load spikes while protecting internal components from thermal damage. To protect operators from severe wrist sprains and hyper-extensions during high-torque binding events, the drill features breakthrough AutoStop™ Control Mode technology. This gyroscopic sensor track catches a sudden bit freeze and stops the motor instantly, flashing a dedicated safety light on the tool's foot to confirm protection. Outfitted with an all-metal 1/2-inch ratcheting chuck for maximum bit grip strength, it is completely ready to upgrade your crew's processing speed.
