The Makita 18V X2 LXT® (36V) Brushless 1-1/8” AVT® Rotary Hammer is a cordless concrete solution that’s loaded with advanced engineering for maximum efficiency. 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. X2 LXT technology delivers up to 140 ½” x 2-3/8” holes per charge when using two 18V LXT 5.0Ah batteries. For reduced vibration, it’s equipped with Anti-Vibration Technology (AVT®). More than just a padded handle, 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. The result is a low vibration rating of only 9m/s², but with no compromise in performance: The efficient brushless motor delivers a full 2.3 ft. lbs. of impact energy, with 250-980 RPM and 0-5,000 BPM. The torque limiting clutch is engineered to prevent gear damage by automatically disengaging the gears if the bit binds, and constant speed control automatically adds power to the motor to maintain speed under load to complete the most demanding jobs. Additional performance features include a electric brake, variable speed dial, built-in L.E.D. light, and a retractable tool hook. For added durability in harsh job site conditions, Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance. It offers dust extraction capability with optional OSHA Table 1 compliant On-Board Dust Extractor Attachment (sold separately). It is ideal for a range of trades including mechanical/electrical/plumbing contractors, concrete contractors, road and bridge contractors, utility workers, pest control, maintenance operations, and more. It accepts SDS-PLUS 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.
