Product Description
The Bosch GBH18V-21 18V Brushless 3/4-Inch SDS-plus® Bulldog™ Rotary Hammer delivers exceptional performance for anchoring in concrete, drilling in masonry, core cutting and chiseling. With 1.5 Ft.-Lbs. of impact energy and a no-load bpm rating of 0-5,100, this hammer work as hard as the user. It provides three modes – rotary hammer, rotation only and hammer only. The brushless motor and low weight of 5.3 Lbs. (tool only, not including battery) maximize runtime for extended applications and provide an outstanding impact-to-weight ratio. The powerful GBH18V-21 is compatible with Bosch 18V Li-ion batteries, but for optimal results, it requires a Bosch 18V 4.0 Ah battery or higher. This hammer works with Bosch PRO+GUARD™ dust solutions – an end-to-end dust-collection system that helps users move toward OSHA Silica dust compliance. It has an ergonomic design and soft-grip handle. It has Electronic Motor and Cell Protection to protect the tool and battery from overload.
