This kit includes the M18CHPX SDS-Plus hammer, two 5.0Ah batteries, a fast charger and a heavy duty box to store the equipment in. The M18CHPX features a POWERSTATE™ brushless motor making it the hardest hitting SDS hammer in its class, easily competing with even corded SDS-Plus hammers. The powerful hammer mechanism delivers 4.0J (EPTA) of impact energy at low 8.6 m/s2 vibrations thanks to the new dual rail anti-vibration system.
