Bosch GBH 18V-34 CF Biturbo Professional Cordless SDS Plus Rotary Hammer, Tool Only

The Bosch GBH 18V-34 CF Biturbo Professional Cordless SDS Plus Rotary Hammer, Tool Only is an 18 V cordless rotary hammer. It is intended for demanding drilling and hammer-drilling work in concrete, masonry and other hard building materials. The cordless format avoids a trailing power cable during construction, installation and renovation work. Maximum drilling diameter is rated at 40 mm in wood and 32 mm in concrete. The concrete capacity is the more relevant figure for the rotary hammer's primary applications.

The rotary hammer weighs 4.9 kg, making the auxiliary handle important for maintaining control during heavier work. Its brushless motor avoids the wear components found in brushed motor designs. The SDS Plus chuck is designed for compatible drill bits and accessories rather than standard straight-shank bits. An included carrying case provides storage and transport for the rotary hammer. The blue housing follows the Bosch Professional design used across the range. No battery or charger is supplied, so both must be obtained separately before use.
