The Milwaukee M18 FUEL HIGH DEMAND 1-1/2" Lineman Magnetic Drill Kit (2788-22HD) drills faster than the number one corded competitor, delivers the strongest magnetic hold on 1/4" steel providing a safer drilling environment in this material, and drills over 75 13/16" holes per charge. By utilizing permanent magnets, the magnetic base operates without electricity; ensuring that the magnet does not deactivate if the battery is drained. Equipped with auto-stop 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 the drill delivers the same 1-1/2" annular cutter capacity as corded. REDLINK Plus Intelligence is the most advanced electronic system on the market, preventing damage to the tool and battery caused by overloading or overheating.
