High-Performance Step Drill Bits

These High-Speed Steel (HSS) step drill bits are engineered for drilling clean, accurate holes across a wide range of materials including steel, aluminum, plastic, and wood. The versatile stepped design allows for creating multiple hole sizes with a single bit, significantly increasing efficiency by reducing the need for frequent tool changes. Enhanced with a titanium nitride (TiN) coating, these bits offer superior wear resistance and extended tool life, making them an essential choice for electrical, plumbing, and HVAC professional applications.
