Step Drill Bits Pilot Hole Maker feature a pilot tip that ensures accurate hole initiation and prevents wandering, enabling precise drilling in metals, plastics, and wood. High-speed steel or coated construction ensures durability and long-lasting sharpness. Step geometry allows multiple diameters to be drilled sequentially without tool changes, while tapered or straight shanks provide secure mounting in drill presses, CNC machines, or hand drills. Spiral flutes aid chip removal and reduce heat buildup. Perfect for prototyping labs, industrial workshops, and DIY projects requiring precision holes.
