Diablo’s new SPEEDemon™ 2-cutter Self-Feed Bits are designed to strict tolerances in the heat forging manufacturing process resulting in energy efficient drilling with up to 2X life per battery charge. Diablo Self-Feed Bits 2-cutter design and an aggressive low thread count feed screw deliver up to 2X more holes per charge. The replaceable feed screw features a pull out stop mechanism that prevents the screw from slipping out when the bit is removed from the material. The combined innovative engineering of Diablo Self-Feed Bits make them the ideal choice for making holes up to 2X faster in soft woods.
