Step Drill Bits for Metal are engineered to drill metals efficiently using progressive diameters in a single tool. High-speed steel or coated construction ensures durability, wear resistance, and sharp cutting edges during repeated use. Spiral flutes evacuate chips effectively, reducing heat and maintaining hole quality. The tapered shank design provides secure mounting in drill presses, CNC machines, or hand drills, minimizing vibration and ensuring precise hole sizes. Suitable for fabrication shops, industrial production, and prototyping labs.
