The 18V LXT® Lithium-Ion Brushless 1” Rotary Hammer (model XRH01Z, tool only, batteries and charger sold separately) is a cordless concrete drilling solution powered by an efficient Makita BL™ Brushless Motor for up to 50% longer run time, increased power and speed, and longer tool life. The XRH01Z delivers 0-950 RPM, 4,700 BPM, and 2.0 Joules of impact energy. Ease-of-use and efficiency features include 3-mode operation (rotation only, hammering with rotation and hammer only), a large 2-finger trigger for more convenience and greater comfort, and a depth adjustment guide for increased drilling depth accuracy. The XRH01Z is compatible with the optional HEPA Dust Extraction Vacuum Attachment (model DX01, sold separately) for improved dust extraction without the cord. 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.
