The Makita XGT® brushless rotary hammer is perfect 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.
