Abrasion Resistant Step Drill Bits are constructed from high-speed steel or coated materials designed to resist wear and maintain sharpness during continuous operations. Step geometry allows sequential drilling of multiple diameters without tool changes, while tapered or straight shanks provide secure mounting in drill presses, CNC machines, or hand drills. Spiral flutes facilitate efficient chip removal and heat reduction. Perfect for fabrication workshops, industrial production, and professional DIY projects that require consistent, long-lasting performance in metals, plastics, and wood.
