Overview
The DEWALT D25481K is a corded rotary hammer drill built for masonry and concrete work rather than light household drilling. At 10.5 amps and 540 RPM it favors torque and hammering force over speed, matching the SDS-style tools contractors use for anchor holes and demolition bits.
The name reads as a plain drill, but the amperage and RPM combination puts it firmly in rotary hammer territory, a tool meant for boring into brick and concrete rather than driving screws or spinning fast in wood. Being corded, it trades battery limits for continuous power on longer jobs. At 13 pounds it has real heft, which helps drive into hard material but also means it is not built for one handed overhead work.
- 10.5 amp corded motor
- 540 RPM output
- 13 pound tool weight
- 17.8 x 17 x 5 inch footprint
Who it's for
Suits tradespeople and serious DIYers doing anchor holes, conduit runs or demolition in masonry and concrete. Not the right pick for someone who wants a lightweight driver for furniture assembly or deck screws, where a standard cordless drill driver is a better fit.
Pros and cons
- Corded design means no battery runtime limits
- Amperage suited to sustained masonry drilling
- Full size body handles demanding holes
- 13 pounds is heavy for overhead or one handed use
- Corded power limits reach away from an outlet
- Not suited to fine wood or drywall driving
Performance notes
The 10.5 amp motor and 540 RPM rating point to a design optimized for hammering force and torque rather than raw spin speed, which is standard for masonry drilling where the bit needs to fracture material as much as rotate through it. Being corded removes battery runtime as a variable, useful on jobs with long continuous holes or repeated anchor sets.
