The Bosch 11255VSR SDS-plus® Bulldog™ Xtreme 1 In. Rotary Hammer is a versatile, handy tool that features a robust 8.0 Amp motor. From anchoring to large material breaking, it gets the job done right the first time. Engineered in the tradition of legendary Bulldogs, this powerful hammer delivers 2.0 Ft.-Lbs. of impact energy and 0-5,800 no-load BPM, but it weighs just 6.7 Lbs. The multifunction mode selector allows users to easily select among three modes of operation: rotary hammer, rotation only and hammer only.

The Bosch RH540M SDS-max® 1-9/16 In. Combination Hammer is a rotary hammer and hammer-only tool designed for concrete contractors and professional remodelers who need a powerful and versatile tool. It delivers 6.1 Ft.-Lbs. of impact energy while weighing in at only 15.2 Lbs. The motor is rated at 170 to 340 RPM in rotary mode and 1,200 to 2,750 BPM in hammer mode, which will easily reduce concrete to dust. Its SDS-max® bit system allows tool-free and one-handed bit changes. The Vario-Lock mechanism lets users angle the chisel into 12 different positions to optimize the working angle. The hammer has a Dual Mode Selector Knob and service minder brushes, which clearly indicate when preventive maintenance is required.
