Details:

The Makita 40 Volt Max XGT cordless rotary hammer kit includes brushless 1-1/8 Inch AVT rotary hammer (GRH01Z), dust extractor attachment with HEPA filter cleaning mechanism (DX12), cloth towel (443122-7), 4.0 Amp-hour battery (BL4040), rapid optimum charger (DC40RA), side handle assembly (126882-3), grease (194683-7) and a tool bag. This cordless hammer tool is a great concrete solution designed for heavy-load applications. It delivers the power, speed and run-time for corded demands without the cord. The XGT technology delivers up to 135 of 3/8 Inch holes per charge when using one 40 Volt max 4.0 Amp-hour battery. Tool features constant speed control that automatically applies additional power under load for optimum performance. It also features Active Feedback-Sensing Technology (AFT) to electronically turn off the motor, if rotation of bit is suddenly forced to stop. The Anti-Vibration Technology (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. Tool with Extreme Protection Technology (XPT™) system is engineered for improved dust, water resistance and added durability in harsh job site conditions.
