The 12V CXT Lithium-Ion Brushless 5/8” Rotary Hammer (RH01Z, tool only, batteries and charger sold separately) is a compact 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 RH01Z delivers 0-680 RPM, 4,800 BPM, and 1.1 Joules of impact energy. Ease-of-use and efficiency features include 2-mode operation (rotation only, hammering with rotation), a variable speed trigger, and a vibration-absorbing handle that moves independently of the motor and hammer mechanism for increased operator comfort.
