This Milwaukee M12CH-0 12v 16mm SDS plus rotary hammer comes with 2 x 4 amp batteries and 1 x rapid charger.
The MILWAUKEE M12 FUEL 16mm 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-ION Battery Pack (sold separately), and REDLINK PLUS Intelligence to deliver a 12V rotary hammer that rivals compact 18V tools on the market today. 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 15.9mm holes in concrete and masonry. For maximum versatility, regardless of application or orientation, the tool also features 2-mode operation, rotary hammer and rotation only.
