Overview
Corded 120V drill from Bosch, drawing 12 amps and turning at a 340 RPM rated speed. At just over 19 inches long and 15.2 lbs, it is built as a full-size corded tool rather than a compact driver.
The 340 RPM rating is well below what a general-purpose drill/driver turns, which points to a tool geared for torque-heavy drilling rather than fast bit-driving. Bosch markets the RH540M in its rotary hammer line, and the low speed paired with a 12 amp motor fits that role: pushing through masonry and concrete rather than spinning wood screws quickly. Buyers should confirm chuck type and bit compatibility before ordering, since that detail is not listed here.
- 120V corded electric motor
- 12 amp draw
- 340 RPM rated speed
- 15.2 lbs, 19 in x 4 in x 10.5 in
Who it's for
Suits tradespeople and serious DIYers doing masonry, concrete or other high-resistance drilling who need sustained corded power. Not the pick for someone wanting a lightweight household drill/driver for furniture assembly or quick wood screws.
Strengths and trade-offs
Drawn from this product's published specifications.
- Corded power avoids battery runtime limits
- 12 amp motor built for high-torque drilling
- Full-size tool at 19 inches for stability
- At 15.2 lbs it is heavy for one-handed work
- 340 RPM is slow for general drilling
- Corded design ties it to an outlet
Performance notes
The 12 amp motor and 340 RPM speed favor torque over rotational speed, the profile of a tool meant to push a bit through dense material rather than drive fasteners quickly. Being corded, output stays constant as long as it's plugged in, without the power fade cordless tools see under heavy load.
