Overview
Drilling through hard material is the job this corded Bosch is set up for, with two speeds and variable speed control. The item type reads corded rotary hammer, and the housing is metal and plastic.
Corded power and a low top speed give a rotary hammer the torque for hard material work. The limits are the unlisted details: bit system, impact rate and carry case are not stated, and the included components field only reads Other.
Who it's for
A shop or garage with an outlet within reach suits the cord and the heavy body. Users who need a light drill for screws or cabinet work, or a battery tool for roof access, should look elsewhere.
Pros and cons
- Corded power, no battery needed
- Variable speed control
- Two speed settings
- Metal drilling capacity listed
- Bit and shank system not listed
- Heavy for overhead work
- Box contents unclear in the listing
Performance notes
A rotary hammer pairs a spinning bit with a hammering action, so the result in hard material depends on the bit and on steady pressure. Top speed is low while the torque rating is high, which favors larger holes over fast small ones. Variable speed allows a slow start before the bit seats.
