The Makita 18V LXT Lithium-Ion cordless 7/8 in. SDS-Plus rotary hammer (model XRH04) delivers faster, more efficient percussive drilling to the jobsite. The versatile XRH04 has 3-mode operation and a built-in torque limiter to ensure stable torque control for a range of concrete drilling tasks, with a more compact design and less vibration. 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 XRH04 features a Makita-built high torque motor that delivers 0-1, 100 RPM, 0-4,000 blows per minute (BPM), and 1.9 joules of impact energy for a wide range of concrete drilling applications. The 3-mode switch allows for hammering, rotation, or hammering with rotation. The XRH04 also delivers two-times faster drilling with synchronized RPM and BPM for more efficient drilling. The built-in torque limiter clutch disengages if the bit jams, and ensures more stable torque control. The XRH04 weighs just 7.0 lbs. with a more compact design at 16-3/8 in. long and an ergonomic shape that fits like a glove for reduced operator fatigue. The shock absorbent handle protects the battery and reduces vibration. In addition, the chisel rotates 360 degrees with 40 different positions to get the best working angle.
