Makita 40-Volt Max XGT Brushless Cordless 1-1/8 in. Rotary Hammer Kit, with Interchangeable Chuck AWS Capable (4.0Ah)

The 40V max XGT Brushless 1-1/8 in. AVT Rotary Hammer Kit with interchangeable chuck (GRH02M1) is a cordless concrete solution designed for heavy-load applications. The quick-change chuck allows the user to switch from SDS-PLUS bits to ½" keyless chuck to utilize straight shank bits. It delivers the power, speed, and run-time for corded demands, without the cord. XGT technology delivers up to 135 of 3/8 in. 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 GRH02M1 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.
