The Bosch GBH18V-28CK28 18V Brushless SDS-plus® Bulldog™ 1-1/8" Rotary Hammer Kit delivers powerful, cordless performance for concrete drilling, chiseling, and heavy-duty applications. Engineered for efficiency and control, this rotary hammer provides an excellent impact-to-weight ratio, producing 2.6 ft.-lbs. of impact energy (EPTA) while weighing only 7.3 lbs (tool only).
Powered by a high-efficiency brushless motor, the GBH18V-28C maximizes runtime and performance for extended jobsite use. The L-shaped design enhances control in both overhead and horizontal drilling, while the 360° adjustable side handle provides flexibility and comfort in multiple working positions.
Advanced safety and comfort features include KickBack Control, which helps reduce the risk of sudden tool reactions during binding conditions, and an anti-vibration system for reduced fatigue during extended use. The Vario-Lock positioning system allows the chisel to be rotated and locked for optimal working angles.
With Bluetooth® connectivity (module sold separately), users can customize tool settings through the Bosch Toolbox app, selecting between Auto, Favorite, and Soft modes for optimized performance. An integrated on-tool user interface provides real-time feedback and control.
Compatible with the Bosch GDE18V-16 dust collection system (sold separately), this rotary hammer supports cleaner jobsite operation. This kit includes two CORE18V® 8 Ah high-power batteries and a fast charger, ensuring maximum runtime and productivity on demanding jobs.
