High Speed Steel Step Drill Bits are designed for precise multi-step drilling in metals, plastics, and composites. Constructed from high-speed steel, these drills maintain sharp edges, resist wear, and provide consistent cutting performance in workshops, fabrication shops, and industrial production. Step drill geometry allows multiple diameters to be drilled sequentially without changing tools, saving time and improving efficiency. Tapered shanks ensure secure mounting in drill presses, lathes, or hand drills, enhancing stability and reducing vibration during operation.
