Step Drills

Stop swapping bits for every size change. Our step drills cut multiple hole diameters fast in sheet metal and thin stock with clean, burr-free results. Go TiN-coated for longer life in stainless and steel, Ferro-Gold for smoother cutting or stepless for dialed-in diameters without center punching. Flats and lobular shanks hold tight so your chuck does not slip.
