The Milwaukee M12 FUEL 5/8 inch SDS Plus Rotary Hammer Kit provides up to 2X more runtime, up to 75% more speed and the largest SDS Plus bit capacity in its class. Milwaukee has combined its exclusive POWERSTATE Brushless Motor, REDLITHIUM Battery Pack, and REDLINK PLUS Intelligence to deliver a 12V rotary hammer that rivals compact 18V tools on the market today. At only 10 inch long and 3.9 lbs, this tool provides performance and runtime that is comparable to a much larger tool, at a fraction of the size and weight. The electropneumatic design allows for drilling of up to 5/8 inch holes in concrete and masonry. For maximum versatility, regardless of application or orientation, the tool also features 2-mode operation, rotary hammer and hammer-only. The kit includes 2 M12 REDLITHIUM XC 4.0 Extended-Capacity Battery Packs, an M12 Lithium-ion Battery Charger, and plastic carrying case.
