Electric rotary hammer GRH01Z

for construction site

The 40V max XGT® Brushless 1-1/8” AVT® Rotary Hammer (GRH01Z, tool only) is a cordless concrete solution designed for heavy-load applications. It delivers the power, speed, and run-time for corded demands, without the cord. XGT technology delivers up to 135 of 3/8” holes per charge when using one 40V max XGT 4.0Ah Battery (sold separately). The Makita-built brushless motor delivers a full 2.8 ft. lbs. of impact energy, with 0-980 RPM and 0-5,000 BPM. Constant speed control automatically applies additional power under load for optimum performance. The GRH01Z 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. The rotary hammer has dust extraction capability with an OSHA Table 1 compliant on-board HEPA dust extractor attachment (sold separately) or standalone with Auto-Start Wireless System (AWS®). 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.
