Super Primalloy® Ultra Step Maintenance Length Drill Bits

With a micro‑center stepped drill point, these bits eliminate center punching or pilot holes. The stepped tip stays cooler for longer tool life and provides clean, burr‑free cuts—even in sheet metal. Maintenance length offers greater rigidity, and flats on the shank reduce chuck slippage. Crafted from premium M series alloy, they excel in industrial or automotive repairs.
