BOSCH 1-9/16-Inch SDS-Max Combination Rotary Hammer RH540M, Blue

CONVENIENT: The Bosch RH540M Combo Rotary Hammer features the SDS-max Bit System for tool-free bit changes with automatic bit locking, dust protection and maximum impact energy transfer rate
POWER: This rotary hammer provides the best in class impact energy of 6.1 ft.-lbs. Weighing only, 15.2 lbs., the RH540M provides maximum productivity in all day drilling and chiseling applications
VERSATILE: The RH540M features a combination dual mode selector knob to allow users to select between hammer drilling, chiseling only and the Vario-Lock function
EFFICIENT: With Varo-Lock Positioning, the rotary hammer rotates and locks chisel into 12 different positions to optimize working angle. The tool also comes complete with service minder brushes to notify users when maintenance is needed
VARIABLE SPEED: The variable speed dial allows for controlled drilling and chiseling applications. 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

Flexible and Functional
The Bosch RH540M 1-9/16-Inch SDS-max Combination Hammer delivers 6.1 ft.-lbs. of impact energy, making it the hardest hitting and fastest drilling rotary hammer in its class. Delivering 38 percent more impact energy than previous generations and up to 20 percent more than other combo rotary hammers in its class, it has a no-load 170 to 340 rpm, while delivering 1,200 to 2,750 blows per minute. This tool easily handles block or tile and drills through tough materials but weighs just over 15 pounds and is only 19 inches in length.

SDS-max and Integral Clutch Bring Convenience
Bosch's SDS-max allows for tool-free and one-handed bit changes, making the combo hammer even more versatile. The operator twists the bit and pushes it until it clicks into place and locks automatically, and it's good to go. The system also provides dust protection and a maximum impact energy transfer rate. The tool's integral clutch disengages the torque transmission if the bit gets into a bind situation, providing protection for the tool and less fatigue for the operator. Constant electronics provide soft start and maintain constant speed under load – this also protects against an overload situation.

Peak Effectiveness
The Bosch RH540M allows the user to get the most productivity from the tool with Vario-Lock Positioning. This mechanism rotates and locks the bit into 12 different positions to optimize the working angle, so the hammer is more effective reducing concrete to dust. A simple twist of the locking sleeve will secure the chisel. The auxiliary handle rotates 360 degrees so the operator can set it exactly where it will be the most operational to use. The auxiliary handle provides additional control and improved depth accuracy.

Adaptable and Effective
The Bosch RH540M Combination Hammer has a Combination Dual Mode Selector Knob allows the tool to be switched between rotary mode or hammer-only mode. This allows for controlled drilling and chiseling applications and precise hole placement. Service minder brushes on the tools also keep them running at maximum capacity, as the tools clearly indicate when preventive maintenance is required. Innovative service modules are designed to let a qualified service technician quickly replace the brushes and cord.
