• 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®) which utilizes Bluetooth® technology for wireless power-on/off communication between tool and dust extractor (AWS® Transmitter sold separately)
• Electric brake allows the tool to be repositioned faster for maximum productivity
• Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears during a bind-up situation

Details: 

The Makita 40 Volt Max XGT® 1-1/8 Inch AVT rotary hammer is powered by a brushless motor that delivers a full 2.8 ft-lb of impact energy, with 0 to 980 RPM and 0 to 5000 BPM. The XGT® technology delivers up to 135 of 3/8 Inch holes per charge when using one 40 Volt max XGT® 4.0 Amp-hour battery. Active feedback-sensing technology which electronically turns off the motor if rotation of bit is suddenly forced to stop and Anti-Vibration Technology (AVT®) for reduced vibration. AVT counterbalances that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. It offers enhanced durability in harsh job site conditions. The vibration-absorbing back handle and side handle minimizes vibration thereby reducing user fatigue.
