Our M18 FUEL™ 1-9/16" SDS Max Rotary Hammer is the first to offer an 18V SDS Max cordless solution. By utilizing proprietary M18 FUEL™ technology, the 1-9/16" SDS Max rotary hammer can drill as fast as corded SDS Max rotary hammers, deliver corded durability, and provide over 20 minutes of continuous chipping. The POWERSTATE™ Brushless Motor delivers 5 ft-lbs of impact energy for the more demanding, heavy-duty applications, including dry coring and medium-duty chipping in both concrete block and reinforced concrete. Powered by the M18™ REDLITHIUM™ FORGE™ XC8.0 battery pack, which delivers up to 5X more run-time, 35% more power, and runs 60% cooler than standard lithium-ion batteries, the 1-9/16" SDS Max Rotary Hammer delivers over 20 minutes of continuous chipping. It also includes REDLINK PLUS™ Intelligence, the most advanced electronic system on the market, to prevent damage to the tool and battery from overloading and overheating. The M18 FUEL™ 1-9/16" SDS Max Rotary Hammer is part of the MILWAUKEE® complete cordless rotary hammer line-up, ranging from Compact SDS Plus to SDS Max, all powered by the M18™ REDLITHIUM™ battery system.
