The 18V LXT Lithium-Ion Brushless 1 in. Rotary hammer (model XRH01Z, tool only) features a Makita BL Brushless Motor technology for up to 50% longer run time. The XRH01Z is the industry's first 1 in. capacity rotary hammer in the 18V cordless category. Its part of Makita's expanding 18V Lithium-Ion series, the worlds largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. 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. The XRH01Z is powered by an efficient BL Brushless Motor with variable speed that delivers 0 to 950 RPM, 4,700 BPM, and 2.0 joules with up to 50% longer run time than current Makita 18V LXT rotary hammers. 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.
