The M18 FUEL 1-1/2 in. magnetic drill drills faster than the number one corded competitor, delivers the strongest magnetic hold on 1/4 in. steel providing a safer drilling environment in this material, and drills over (66) 13/16 in. holes per charge. By utilizing permanent magnets, the magnetic base operates without electricity; ensuring that the magnet does Nt deactivate if the battery is drained. Equipped with AutoStop lift-off detection, power to the motor is automatically cut if excess rotational motion is detected while drilling. Powered by a MILWAUKEE POWERSTATE brushless motor, both drills are faster than their corded counterparts, and deliver the same 1-1/2 in. annular cutter capacity. REDLINK PLUS intelligence is the most advanced electronic system on the market, preventing damage to the tool and battery caused by overloading or overheating. The M18 REDLITHIUM HIGH OUTPUT XC8.0 battery pack provides 50% more power and runs 50% cooler vs REDLITHIUM XC batteries. It maintains full power and runs substantially cooler through heavy applications, allowing users to push their cordless tools harder and longer than ever before. The M18 REDLITHIUM HIGH OUTPUT XC8.0 battery is fully compatible with 200+ M18 tools.
