Powered by Fuel technology, the M18 Fuel 1 inch SDS Plus Rotary Hammer delivers faster than corded speed, corded durability, and all day work on one charge. The Milwaukee POWERSTATE Brushless Motor Provides 1.7 ft-lbs of impact energy, 0-1,400 RPM, and 0-4,900 BPM. The Milwaukee REDLITHIUM XC5.0 Battery Packs provide all day work on one charge, 20% more power, and 2X more life than standard Lithium-Ion batteries. REDLINK PLUS Intelligence integrates full-circle communication between tool, battery and charger to protect from overloading, overheating, and over-discharging. Milwaukee HAMMERVAC Dedicated Dust Extractor (2712-DE) features an inline dedicated design engineered to connect directly to and be power by the M18 FUEL 1 Inch SDS Plus Rotary Hammer (2712-22). This design allows for a very compact HAMMERVAC and rotary hammer combination to fit in the most confined work spaces. Utilizing the same replaceable certified HEPA filter as other HAMMERVACS, which filter 99.97% of all particles greater than 0.3 micro m, means more compatibility on the jobsite.
