M12 FUEL™ 1/2" Hammer Drill/Driver

The Milwaukee 3404-20 M12 FUEL™ 1/2" Hammer Drill/Driver is a subcompact, high-performance cordless drill designed for professionals who need strong drilling capability in the tightest work areas. It combines hammer drilling capability with a compact footprint, making it one of the most versatile tools in the M12 lineup.

Powered by a POWERSTATE™ brushless motor, this drill delivers up to 400 in-lbs of torque, providing enough power for wood, metal, and light masonry drilling applications while maintaining excellent control and portability. It is engineered to maintain speed under load, so performance stays consistent even in tougher materials.

At only about 6 inches in length, this is one of the most compact hammer drills in its class, making it ideal for overhead work, tight framing cavities, electrical panels, and confined service areas where larger M18 drills cannot easily fit.

The tool features an all-metal 1/2" chuck and all-metal gearcase, giving it durability and secure bit retention under demanding jobsite use. A mechanical clutch provides consistent torque control for fastening, helping prevent overdriving screws in softer materials.

Hammer mode adds light masonry capability, allowing it to drill into brick, block, and concrete in light-duty applications when a full-size hammer drill is not required.

REDLINK PLUS™ intelligence continuously monitors the tool and battery to prevent overload and overheating while optimizing performance under load.
