HSS Spiral Step Drill Bit, 4-32 mm or 6-60 mm

Make several hole sizes with one stepped drill bit in a suitable material. Spiral flutes and a round shank provide a practical format for matched sheet-work and DIY drilling tasks.

✅ Change hole diameter without changing bits - Multiple steps provide a sequence of cutting sizes.

✅ Open a hole progressively - The stepped profile lets you work towards the required diameter.

✅ Choose the size range - 4-32 mm and 6-60 mm versions suit different projects.

Match the Material Thickness to the Step

Select a bit and drilling method suited to the material, thickness and machine. A step's usable depth limits how thick a single-diameter hole can be.

The HSS bit has a spiral-flute design and round shank. Secure the workpiece, use the correct speed and lubrication where required, and avoid forcing the larger steps into the work.
