The Milwaukee® M12 FUEL™ 5/8” SDS Plus Rotary Hammer 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 (sold separately), and REDLINK PLUS™ Intelligence to deliver a 12V rotary hammer that rivals compact 18V tools on the market today. At only 10” 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” 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.
