Threaded Shank Drill Bits

Tight access and an aircraft drill in your hand? These 1/4"-28 threaded shank bits stay locked in for rivet and machine-screw holes in cramped bays. The 135° split point bites fast and helps prevent walking. Choose stubby or short for clearance, long for reach. Go HSS for everyday work, M42 cobalt for heat and longer life.
