Milwaukee M18 FUEL 2904: The Hammer Drill for Professionals

Introduction

The Milwaukee M18 FUEL 2904 represents the pinnacle of cordless hammer drill technology, designed specifically for professionals who demand maximum power and performance. As Milwaukee’s flagship hammer drill in the M18 FUEL lineup, the 2904-20 model delivers unprecedented torque, speed, and versatility while maintaining a surprisingly compact form factor. Whether you’re a contractor, electrician, plumber, or serious DIY enthusiast, this tool promises to handle the most demanding drilling and fastening applications with ease. In this comprehensive review, we’ll examine what makes the Milwaukee 2904 stand out in an increasingly competitive cordless tool market and determine if it lives up to its bold claims.

Key Specifications

Pros and Cons

Detailed Performance Review

Power and Torque

The Milwaukee 2904-20 delivers an impressive 1,400 in-lbs of torque, making it one of the most powerful cordless hammer drills on the market. During testing, this raw power was immediately apparent when drilling through dense materials. The drill effortlessly powered through 2-inch holes in pressure-treated lumber using a spade bit without bogging down. Even more impressively, when equipped with a 3-inch hole saw, it cut through multiple layers of plywood with minimal strain.

Where this hammer drill truly shines is in masonry applications. The hammer function combined with the substantial torque allows it to drill into concrete with surprising efficiency. In our tests, it drove a 1/2-inch bit into cured concrete nearly as quickly as many corded models, making it a viable replacement for dedicated corded hammer drills in many applications.

Design and Ergonomics

Despite its substantial power, Milwaukee has managed to keep the 2904 relatively compact at just 6.9 inches in length. This design consideration pays dividends when working in confined spaces like cabinets, between studs, or overhead. The grip features Milwaukee’s standard rubber overmold that provides excellent comfort and reduces vibration transfer to the hand.

At 3.2 pounds (without battery), it’s not the lightest drill in its class, but the weight distribution is well-balanced. When paired with a high-capacity battery like the M18 5.0Ah, the tool feels substantial but manageable for extended use. The included side handle is a necessity when using the drill at maximum torque, providing crucial stability during high-torque applications.

The all-metal ratcheting chuck deserves special mention. It grips bits securely with no slippage even under heavy load, and the ratcheting mechanism allows for easy one-handed bit changes. This is a significant improvement over plastic-component chucks found on less premium models.

Intelligent Features

The Auto-Stop™ Control Mode is one of the most valuable features of the 2904. When engaged, this mode automatically stops the drill when it senses the fastener is fully seated, preventing over-driving and potential damage to materials or fasteners. This proves especially useful when installing cabinet hardware, electrical boxes, or any application where precise fastener seating is critical.

Milwaukee’s REDLINK PLUS™ Intelligence system monitors temperature, manages power output, and prevents damage from overloading. During extended use, this system noticeably maintains consistent performance without the power fade experienced with less sophisticated tools.

The two-speed gearbox (0-550/0-2,000 RPM) provides versatility across applications. The lower speed delivers maximum torque for driving large fasteners or drilling large holes, while the higher speed setting is perfect for smaller diameter drilling in wood or metal.

Battery Performance

While the 2904-20 is sold as a bare tool, its performance is directly tied to the M18 battery platform. When paired with Milwaukee’s newer high-output batteries, runtime is exceptional. During testing with an M18 5.0Ah battery, the drill completed over 100 1-1/2 inch holes in 2x material on a single charge.

The drill’s brushless motor contributes significantly to this efficiency, generating less heat and requiring less power than brushed alternatives. This translates to longer runtime and extended motor life. The battery fuel gauge is a convenient feature that allows users to monitor remaining charge at a glance.

Comparison with Alternatives

The Milwaukee 2904 stands out with class-leading torque and the most compact design among premium hammer drills. While the DeWalt DCD998 offers a third speed setting that provides additional versatility, it can’t match the Milwaukee’s raw power or compact form factor. The Makita XPH07Z offers excellent performance at a slightly lower price point but falls short in maximum torque and lacks the intelligent features of the Milwaukee.

Real-World Applications

Construction and Framing

On framing and construction sites, the 2904 excels at drilling through multiple layers of dimensional lumber and driving large lag bolts. The hammer function makes quick work of concrete anchors when mounting sill plates or other structural elements. The compact size allows it to fit between studs when drilling electrical or plumbing passages.

Electrical and Plumbing Work

For electrical and plumbing professionals, the Auto-Stop™ feature proves invaluable when installing boxes and fixtures, preventing stripped screws and damaged materials. The powerful hammer function easily creates holes for anchors in concrete or brick walls, while the compact design helps when working in electrical panels or under sinks.

Cabinetry and Finish Work

Despite its power, the 2904 offers enough finesse for cabinet installation and finish carpentry. The multiple clutch settings and Auto-Stop™ function prevent over-driving delicate hardware, while the power is there when needed for drilling through solid hardwoods or driving cabinet screws.

DIY and Home Projects

For serious DIY enthusiasts, this drill may represent overkill for occasional use but provides room to grow into more demanding projects. The versatility means it can handle everything from hanging pictures to building decks or renovating bathrooms.

Durability and Reliability

Milwaukee’s reputation for durability is well-represented in the 2904. The all-metal gearbox and chuck are designed to withstand jobsite abuse, while the reinforced housing protects internal components from drops and impacts. The brushless motor eliminates the wear associated with carbon brushes, significantly extending the tool’s service life.

User reports from professional contractors who have used the drill daily for months indicate exceptional reliability with no significant issues. Milwaukee backs this confidence with a 5-year warranty, which exceeds the industry standard and provides peace of mind for professionals who depend on their tools for their livelihood.
