Drill Bit Sets

Bits scattered and dull points kill time fast. Kimball Midwest's drill bit sets keep the right geometry in one case for clean starts and accurate holes. Run step and Taper-Kut for sheet and panels, parabolic flutes for deeper holes, cobalt or carbide for heat and hard alloys, left-hand to back out broken bolts, masonry for concrete and tile, tap drills to protect your threads.
