@138construction: Ran the M18 FUEL™ 1-9/16" SDS Max Rotary Hammer w/ ONE-KEY™ with the M18™ REDLITHIUM™ FORGE™ HD12.0 battery on it. Drills as fast as a corded SDS Max, and the anti-vibration system kept it smooth in hand the whole time. Big thanks to Milwaukee Tool for hooking us up with this one. #MilwaukeeTool #NothingButHeavyDuty @Milwaukee Tool
