M18 FUEL 1/2" Hammer Drill/Driver

The Milwaukee M18 FUEL 1/2" Hammer Drill/Driver (2904-20) is the industry's most powerful cordless hammer drill, built for professionals who need maximum torque and drilling capacity in dense materials. This bare tool delivers 1400 inch-pounds of torque through a POWERSTATE Brushless Motor, enabling it to drill 2-9/16" self-feed holes in dense woods at high speed. At only 6.9" in length, it's the most compact solution in its class while offering AutoStop Control Mode for enhanced operator safety in bind-up situations. This tool is designed for electricians, plumbers, HVAC technicians, and general contractors who demand both power and maneuverability in tight spaces.

• POWERSTATE Brushless Motor: Delivers the highest power under load in its class, enabling drilling of the largest diameter holes (up to 2-9/16" self-feed) in the densest woods for increased job site productivity.
• Most Compact Design (6.9" Length): Provides superior access into tight spaces between studs, joists, and mechanical equipment while reducing operator fatigue during overhead or extended use.
• AutoStop Control Mode: Detects bind-up conditions and stops rotation in the fastest reaction time in the industry, protecting operators from over-rotation injuries. A dedicated AutoStop indicator light on the tool's foot signals when a protection event occurs.
• 1400 Inch-Pounds of Torque: Powers through the widest range of drilling and fastening applications, from driving large lag bolts to boring through engineered lumber and steel.
• 1/2" All-Metal Ratcheting Chuck with Carbide Teeth: Maximizes bit retention and durability while resisting corrosion from job site conditions. The ratcheting lock design provides superior grip strength compared to keyless chucks.
• REDLINK PLUS Intelligence: Protects the tool and battery from overloads, overheating, and over-discharge, ensuring maximum performance and extended system life.
• Mechanical Clutch: Delivers consistent performance when driving a wide range of fastener sizes and types, from deck screws to lag bolts.
• Hammer Drill Mode: Enables fast drilling into brick, block, and concrete without requiring a separate rotary hammer for light masonry work.

This tool requires M18 REDLITHIUM battery packs (sold separately, 0 batteries included). It is compatible with all M18 lithium-ion batteries in the Milwaukee system. For maximum runtime, Milwaukee recommends using XC5.0Ah or higher capacity batteries. The tool uses standard 1/2" shank drill bits and driver bits.

The all-metal belt clip attaches to either side of the tool for portability on job sites. The LED light activates automatically to improve visibility in low-light work areas. Regular maintenance involves keeping the chuck jaws clean and free of debris, checking that bits are fully seated before operation, and storing the tool in a dry location when not in use.
