TECWERK sheet-metal step drill set, HSS, 3–14 / 4–20 / 16–30.5 mm

TECWERK sheet-metal step drill set offers a compact cutting solution for producing a range of hole diameters in thin metal sheets and related fabrication tasks.

• High-speed steel HSS for durable cutting
• Step ranges 3–14, 4–20 and 16–30.5 mm
• Shank with three clamping flats
• Supplied in a plastic case

Faster holemaking with fewer tool changes

The stepped geometry enables production of several hole diameters with a single tool, which leads to reduced tool changes and a measurable improvement in machining throughput. Made from HSS, the set maintains cutting edge integrity for longer runs in thin materials, supporting predictable cycle times. For workshops focused on efficiency, this combination of versatile hole sizes and robust material properties improves process flow and minimises downtime.

Secure clamping and tidy storage for workshop reliability

A shaft designed with three clamping flats ensures positive grip in chucks and collets, reducing slippage and improving concentricity during drilling. The entire set is supplied in a plastic case, which supports orderly storage and transport between workstations. These practical features contribute to consistent hole quality and simplified tool management on the shop floor.

Practical application guidance and compatibility

Intended primarily for sheet-metal operations, the set is suited to drilling and enlarging holes where stepped diameters and rapid size changes are required. The stepped cutters perform best at appropriate spindle speeds and light feed for thin materials to avoid burring. Routine sharpening or replacement keeps performance optimal; the compact format supports mobile tool kits and bench setups, bringing dependable capability to assembly, maintenance and fabrication tasks.
