The Makita 18V X2 LXT® (36V) Brushless 1-9/16” advanced AVT® rotary hammer with AWS is a cordless concrete solution that’s loaded with advanced engineering for maximum efficiency. It’S equipped with auto-start wireless system (AWS) for wireless connectivity with an aws-equipped dust extractor (sold separately), and features advanced AVT® for reduced vibration. It’S powered by two 18V LXT® batteries (sold separately) and an efficient Brushless motor for maximum power, speed and run-time for corded demands, without the cord. The XRH07ZKU is engineered with advanced Anti-Vibration technology (AVT®), a synchronized three-component system for significantly less vibration. Avt® is more than just a padded handle. The three-component system includes an internal counterbalance that uses air pressure to move counterweight Pistons in the opposite direction of the drive piston to actively reduce vibration. The result is a low vibration rating of only 5M/s², but with No compromise in performance: the efficient Brushless motor delivers a full 8.4 ft. Lbs. Of impact energy, with 250-500 RPM and 1, 450-2, 900 BPM. For improved efficiency, it’s equipped with auto-start wireless system technology. Aws utilizes Bluetooth® technology for wireless communication between the tool and dust extractor (sold separately). when the trigger of the aws-equipped XRH07ZKU is engaged, the aws-equipped dust extractor powers-up. When the trigger is released, the dust extractor powers-down. Aws is intelligent communication that eliminates cords and excessive noise since the dust extractor runs only when the tool is running. Additional performance features include a torque limiting clutch engineered to prevent gear damage by automatically disengaging the gears if the bit binds, and Constant speed control that automatically adds power to the motor to maintain speed under load to complete the most demanding jobs. Soft start technology suppresses start-up reaction for more precision and better accuracy, and the soft no-load function automatically reduces the speed of the motor when idling – this helps increase tool life and battery run-time. The XRH07ZKU is engineered for a range of concrete applications including drilling/coring through-holes for pipes, setting larger anchors, securing tilt-wall supports, small chipping applications, and more. It is ideal for a range of trades including masons, concrete contractors, demolition contractors, plumbers, electricians, Sprinkler installers, and general contractors seeking a best-in-class rotary hammer. It accepts SDS-MAX bits. It’S part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star protection Computer controls™. Star protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT® and compact Lithium-Ion batteries with the Star symbol on the battery indicating Star protection inside.
