Milwaukee M12 FUEL 1/2 in Hammer Drill-Driver (Bare Tool) | Brushless, Lightweight 12V

Meet the Milwaukee M12 FUEL 1/2" Hammer Drill/Driver (3404-20) in bare-tool form. This compact 12V cordless tool centers on a brushless motor, delivering dependable power while keeping weight low enough to wear on a belt all day. When paired with your existing M12 batteries, it becomes a flexible companion for a wide range of small to mid-size tasks, from quick hole work to precise screw driving.

Power, speed, and control in a subcompact package

The brushless motor prioritizes efficiency and smooth operation, enabling confident drilling and driving across a broad spectrum of fasteners and bits. Under load, the tool responds quickly, helping you move through tasks without unnecessary pauses. The 1/2" all-metal chuck enhances durability, grip, and bit retention in challenging materials, while the mechanical clutch helps you dial in driving depth for repeatable results as you switch between fasteners.

Lightweight design for comfortable, all-day use

Rounding out its practical design, the tool weighs about 2.6 pounds, making it easier to maneuver on ladders, in cabinets, or along trim work. The compact silhouette reduces fatigue and lets you work in tight spaces, overhead positions, or crowded corners. Being a bare tool means you’ll supply your own battery and charger from Milwaukee’s M12 lineup, keeping your kit modular and ready for expansion when needed.

Real-world tasks where this drill-driver shines

• Fast drilling in wood, plastics, and light metal with controlled bit engagement.
• Efficient screw driving with the clutch to prevent overdriving and wobble in dense fasteners.

• Low-profile ergonomics support cabinetry, shelving, and automotive trim work without fatigue.
• Durable chuck and clutch geometry enable repeatable results across multiple sessions and projects.

Why it fits into the Milwaukee M12 system

As part of the M12 ecosystem, this bare tool integrates with existing batteries and chargers, offering a scalable setup for DIYers and professionals alike. The bare tool format lets you tailor your kit to your current battery count while leaving room for future expansion.
