The Milwaukee M12 FUEL 5/8 in SDS plus rotary hammer kit provides up to 75% faster drilling, up to 70% less vibration and up to 2X more runtime 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 12 V rotary hammer that rivals compact 18 V tools on the market today. At only 10 in long and 3.9 lb, this tool provides performance and runtime that is comparable to a much larger tool, at a fraction of the size and weight. The electro pneumatic design allows for drilling of up to 5/8 in holes in concrete and masonry. For maximum versatility, regardless of application or orientation, the tool also features two mode operation, rotary hammer and rotation only. The kit includes 2 M12 REDLITHIUM XC 4.0 extended capacity battery packs, an M12 Lithium-Ion battery charger and plastic carrying case.
