18V SDS-plus® 3/4 In. Rotary Hammer Kit

The Bosch GBH18V-20K21 18V SDS-plus® 3/4 In. Rotary Hammer kit features a light, portable rotary hammer with an exceptional impact-to-weight ratio – to deliver performance and efficiency. It requires a Bosch 18V 4.0 Ah battery or higher. With 1.3 Ft.-Lbs. of impact energy and a no-load BPM rating of 0-4,550, it will work as hard as the user. It provides three modes of operation – rotary hammer, rotation only and hammer only. This hammer works with Bosch PRO+GUARD™ dust solutions, an end-to-end dust-collection system that helps users move toward OSHA Silica Table 1 dust compliance. At only 5.7 Lbs. (tool only, not including battery), it has an ergonomic design and soft-grip handle. It has Electronic Motor and Cell Protection to help protect the tool and battery from overload. The kit includes two 18V 4.0 Ah FatPack batteries and an 18V charger.
