The 18V LXT Lithium-Ion Brushless 1 in. Rotary hammer with HEPA dust traction vacuum attachment (model XRH01ZVX, tool only) combines Makita BL Brushless Motor technology with concrete dust extraction - without the cord. The XRH01ZVX is the industry's first 1 In. capacity rotary hammer in the 18V category, and sets new standards in the cordless tool 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 XRH01ZVX 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. The efficiency of the BL Brushless Motor allowed Makita engineers to power both the tool and the separate vacuum motor with a single 18V (not 36 V) Lithium-Ion battery (sold separately). The separate vacuum motor also increases suction efficiency without sacrificing the performance of the rotary hammer. The result is a powerful and efficient rotary hammer with vacuum attachment that delivers the same drilling capacity as the leading competitors 36 V rotary hammers, but with up to 2.5 lbs. less weight (with battery, sold separately).
