Milwaukee M18 FUEL 2904-20 Hammer Drill/Driver

The flagship M18 hammer drill with class-leading torque.

Our verdict

The 2904-20 is the M18 flagship hammer drill: 1,400 in-lbs, up to 2,100 RPM, and a hammer mode, in a body only 6.9 inches long. It is sold tool-only because its buyers already own M18 batteries by the crate.

What we like

  • 1,400 in-lbs of max torque leads the pro class
  • Hammer mode covers masonry anchors alongside wood and steel
  • 6.9-inch length stays compact for a flagship hammer drill
  • Brushless FUEL motor built for daily site work

What to watch out for

  • Tool only; M18 batteries and charger are separate purchases
  • Flagship pricing reflects its pro positioning
  • Overkill for furniture assembly and light home tasks

What owners report: Milwaukee M18 FUEL 2904-20 Hammer Drill/Driver

Synthesized from recurring themes in long-term owner feedback.

Most praised

  • Flagship torque drives the largest fasteners pros meet without breaking stride
  • Hammer drilling plus this compact length is a combination site crews value daily
  • The FUEL build feels like it expects years of daily trade use

Common complaints

  • Tool only pricing means the real entry cost includes batteries and a charger
  • Flagship money is hard to justify for occasional home projects
  • Its power is wasted, and its weight felt, on light assembly tasks

Who it is for

Professional crews and serious M18 users drilling anchors and driving structural fasteners.

Torque and speed

At 1,400 in-lbs the 2904 out-torques every drill in this guide, and the two-speed gearbox reaches 2,100 RPM for fast drilling in wood and steel. This is the drill for ledger bolts and big auger bits, not for flat-pack furniture.

Hammer mode and size

The hammer function covers masonry anchor work that pure drill drivers cannot touch, while the 6.9-inch head length keeps the flagship usable between studs and inside mechanical spaces.

Tool-only economics

No battery or charger is included. For an M18 crew that is a feature, lower cost for the tool alone; for a first-time buyer it makes the kit drills in this guide the rational purchase.

Questions, answered

Does the 2904-20 include batteries?

No, it is a bare tool. Budget for M18 batteries and a charger if you are not already on the platform.

Can it drill into concrete?

Its hammer mode handles masonry anchor holes in brick, block, and concrete. Sustained large-diameter concrete work belongs to a rotary hammer.
