Bosch GBH18V-34CQ 18V 8-Amp SDS-plus Variable Speed Cordless Rotary Hammer – 4.3 Ft.-Lbs Impact, BITURBO Brushless, PROFACTOR

The Bosch GBH18V-34CQ 18V SDS-plus Bulldog Rotary Hammer delivers corded-level performance in a cordless, portable design—perfect for heavy-duty concrete drilling and chiseling. Part of the PROFACTOR System, it combines BITURBO Brushless Technology with a CORE18V PROFACTOR battery (sold separately) for unmatched efficiency and power in its class.

With an impressive 4.3 ft.-lbs. of impact energy (EPTA), this 1-1/4" rotary hammer tackles the toughest concrete jobs with ease. The anti-vibration system reduces user fatigue, while KickBack Control enhances safety by minimizing sudden tool reactions in binding situations.

The quick-release chuck allows for seamless switching between SDS-plus and three-jaw chucks for versatile bit use. A Vario-Lock mechanism enables you to rotate and lock the chisel into multiple positions for the optimal working angle. The on-tool user interface provides instant performance feedback and allows customization when paired with the Bosch Toolbox App (connectivity module sold separately).
