Step Drill Bits

Our Step Drill Bits are ideal for drilling, enlarging, and deburring holes in thin materials such as sheet metal, stainless steel, aluminum, and plastic. With a unique stepped design, one bit can perform the work of multiple drills, saving time and effort. Each step is clearly marked for fast size identification and accurate hole making.

Manufactured from premium HSS and HSS-Co (cobalt alloy) with titanium nitride (TiN) coating, our step drills offer excellent wear resistance, heat resistance, and extended service life. They are widely used in electrical work, HVAC, automotive repair, and general fabrication.
