1-9/16" High Power SDS-Max Rotary Hammer delivers 8.4 ft. lbs. of Impact Energy 250-500 RPM, 1,450-2,900 BPM
Makita-built brushless motor along with 40V max XGT® battery combine to deliver the power performance required for heavy-load application
Constant speed control automatically applies additional power under load for optimum performance
Automatic-start Wireless System (AWS®) for wireless power-on/off communication between tool and dust extractor (AWS® Transmitter sold separately)
Active Feedback-Sensing Technology (AFT®) electronically turns off the motor if rotation of bit is suddenly forced to stop
The 40V max XGT® Brushless 1-9/16” AVT® Rotary Hammer Kit (GRH05M1) is a cordless concrete solution designed for heavy-load applications. It delivers the power, speed, and run-time for corded demands, without the cord. The GRH05M1 features Active Feedback-Sensing Technology (AFT®), which electronically turns off the motor if rotation of bit is suddenly forced to stop, and Anti-Vibration Technology (AVT®) for reduced vibration. More than just a padded handle, AVT is an internal counterbalance that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. In addition, the vibration-absorbing back handle and side handle further reduce vibration. For added durability in harsh job site conditions, Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance. Auto-Start Wireless System (AWS®) uses Bluetooth® technology for wireless power-on and power-off communication between the equipped tool and dust extractor. Once connected via AWS, the AWS-equipped dust extractor will automatically power on or off when the AWS-equipped cordless tool starts or stops, running only when the tool is in use. This increases productivity on a single charge and reduces continuous noise at the job or work site. Constant speed control automatically applies additional power under load for optimum performance. The torque limiting clutch is engineered to prevent gear damage by automatically disengaging the gears if the bit binds, and constant speed control automatically adds power to the motor to maintain speed under load to complete the most demanding jobs. Additional performance features include an electric brake, variable speed dial, built-in L.E.D. light, a soft-start to suppress start-up reaction, and Soft No-load function that automatically reduces the speed of the motor when idling. The Rotary Hammer has dust extraction capability an optional Makita Dust Attachment Kit (sold separately). It has 2-modes of operation - "Hammering with Rotation" or "Hammering Only". The GRH05M1 is ideal for a range of trades including mechanical/electrical/plumbing contractors, concrete contractors, road and bridge contractors, utility workers, pest control, maintenance operations, and more. It accepts SDS-MAX bits.
