Overview
The Bosch GBH2-28L is a corded electric drill drawing 8.5 amps at 120 volts and spinning up to 1,230 RPM. At 2.9 kilograms it sits at the heavier end of corded drills, built for repeated use rather than light household jobs.
An 8.5 amp motor is a substantial draw for a drill, and paired with a top speed of 1,230 RPM it points toward a tool built for boring larger holes and driving through dense material rather than fast, light drilling. The corded design trades portability for continuous power, so runtime is not a concern the way it is with battery tools. No chuck size or torque setting count is given in the listing, so match those details against your bit sizes before buying.
- 8.5 amp corded motor
- 120 volt power source
- 1,230 RPM top speed
- 2.9 kilogram (6.4 lb) tool weight
Who it's for
Fits contractors and heavy DIYers who need sustained corded power for drilling through masonry, wood, or metal on a job site. Less suited to occasional users who would find a lighter cordless drill easier to maneuver.
Strengths and trade-offs
Drawn from this product's published specifications.
- 8.5 amp motor for sustained heavy drilling
- Corded design means no battery runtime limits
- Geared for torque with a 1,230 RPM top speed
- Corded, so working radius is limited by the cable
- At 2.9 kilograms it is heavier than typical cordless drills
- No chuck size listed to confirm bit compatibility
Performance notes
The 8.5 amp draw at 120 volts gives the motor enough current to hold speed under load, which matters more for boring large diameter holes than for driving small screws. A 1,230 RPM top speed is on the slower side for a drill, consistent with a tool geared for torque over speed.
