BOSCH RH540M 1-9/16" SDS-max Combination Hammer

The BOSCH® RH540M 1-9/16" SDS-max Combination Hammer is a powerful and versatile solution for concrete contractors and professional remodelers. Combining rotary hammer and hammer-only modes, this heavy-duty tool delivers 6.1 ft-lbs of impact energy while weighing just 15.2 lbs.

The powerful motor provides 170–340 RPM in rotary mode and up to 2,900 BPM, delivering the performance needed for demanding concrete drilling and chiseling applications. The SDS-max bit system provides tool-free, one-handed bit changes while automatically locking bits in place for efficient operation and maximum impact energy transfer.

The Vario-Lock system allows chisels to be rotated and locked into 12 different positions, helping users optimize the working angle for each application. An integral clutch helps protect the operator and tool by disengaging torque transmission if the bit binds, while service minder brushes provide an indication when preventive maintenance is required.
