Makita 40V Max XGT Brushless Cordless 1-9/16" AVT Rotary Hammer, accepts SDS-MAX bits, AFT, AWS Capable Bare Tool - GRH05Z
The Makita XGT brushless rotary hammer is ideal to use on concrete surfaces and produces optimum speed, power and runtime for corded applications. If the rotation of the wheel comes to a stop, the active feedback-sensing technology turns off the motor immediately. Internal counterbalance of the Anti-Vibration Technology (AVT) utilizes air pressure in order to move counterweight pistons in the exact opposite direction of the drive piston thus minimizing vibration of the tool. Back handle as well as the side handle absorbs all the vibration to ensure user comfort. Extreme protection technology prevents the accumulation of water and dust on the tool even in harsh conditions. The XGT technology makes use of 40 Volt Lithium batteries to produce optimum power in high demand applications. Auto-start wireless system makes use of Bluetooth technology to facilitate wireless communication between the tool and the dust extractor. This AWS technology enhances the productivity on a single charge and minimizes noise on the jobsite.
Features
- OUTPOWER: Makita-built brushless motor along with 40V max XGT battery combine to deliver the power performance required for heavy-load application
- OUTSMART: Auto-start Wireless System (AWS) utilizes Bluetooth technology for wireless power-on/off communication between tool and dust extractor (AWS Transmitter sold separately)
- OUTLAST: Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions
- Anti-Vibration Technology (AVT) is an internal counterbalance system along with vibration-absorbing handles that work together to reduce vibration
- Active Feedback-Sensing Technology (AFT) electronically turns off the motor if rotation of bit is suddenly forced to stop
- Electric brake allows the tool to be repositioned faster for maximum productivity
- Dust extraction capability with optional Makita Dust Attachment Kit
- Constant speed control automatically applies additional power under load for optimum performance
- Soft start suppresses start-up reaction for more precision and better accuracy
- Soft no-load
