Makita (GRH01M1) 40V Max XGT Brushless Cordless 1-1/8 In. AVT Rotary Hammer Kit - GRH01M1

Features: 

• OUTPOWER: Makita-built brushless motor along with 40V max XGT battery combine to deliver the power performance required for heavy-load application
• OUTSMART: Constant speed control automatically applies additional power under load for optimum performance
• OUTLAST: Overload protection is designed to protect the motor from burnout in abnormally high torque situations
• XGT technology delivers up to 135 of 3/8" holes using a fully charged 40V XGT 4.0Ah battery*
• Active Feedback-Sensing Technology (AFT) electronically turns off the motor if rotation of bit is suddenly forced to stop
• Anti-Vibration Technology (AVT) is an internal counterbalance system along with vibration-absorbing handles that work together to reduce vibration
• Dust extraction capability with OSHA Table 1 compliant on-board HEPA Dust Extractor or stand-alone AWS Extractor options
• Auto-Start Wireless System (AWS) utilizes Bluetooth technology for wireless power-on/off communication between tool and dust extractor (AWS Transmitter and dust extractor sold separately)
• Electric brake allows the tool to be repositioned faster for maximum productivity

Details:

The 40V max XGT Brushless 1-1/8” AVT Rotary Hammer Kit (GRH01M1) 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. 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 GRH01M1 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.
