Diablo 2-1/4 in. x 5-1/8 in. Self-Feed Drill Bit

The Diablo 2-1/4 in. x 5-1/8 in. Self-Feed Drill Bit is engineered for fast, clean, and energy-efficient drilling in wood. Manufactured through a precision heat-forging process to strict tolerances, this bit delivers maximum durability and extended cutting life per battery charge. Featuring a two-cutter head design and an aggressive low-thread-count feed screw, this self-feed bit produces fast hole-making while preventing pitch build-up. The replaceable feed screw includes a pull-out stop mechanism to keep the screw securely in place when retracting the bit from the workpiece.
