US PRO 7141 6–60mm HSS-G+ Spiral Step Drill

The US PRO 7141 6–60mm HSS-G+ Spiral Step Drill is designed to deliver maximum versatility and clean cutting performance when drilling a wide range of hole sizes with a single tool. Ideal for workshop, fabrication, and maintenance work, this step drill removes the need for constant bit changes while maintaining accuracy and control.

Manufactured from high quality HSS-G+ high speed steel and heat treated for increased hardness, the drill offers excellent durability and long service life. The spiral fluted step design improves chip removal and cutting efficiency, helping to reduce heat build-up and produce smoother, more consistent holes.

The stepped cutting range covers 6mm through to 60mm, making it well suited for applications involving sheet metal, aluminium, non-ferrous metals, and PVC. Each step is clearly defined, allowing controlled enlargement of holes without snagging or tearing the material.

Fitted with a 13mm diameter 3-flat shank, the drill provides a secure grip in the chuck, reducing the risk of slipping under load. With an overall length of 113mm and a compact, balanced design, it is suitable for both hand-held drills and drill presses.
