TECWERK machine tap M5 x 0.8 mm (DIN 371C) — HSS‑Co, 40° spiral flute

A TECWERK machine tap M5 x 0.8 mm engineered for producing metric ISO blind threads in difficult‑to‑machine steels, offering durable cutting geometry and consistent tolerance control

• HSS‑Co construction for hard steels
• 40° right‑hand spiral flute for blind holes
• ISO metric thread M5 x 0.8, tolerance ISO2 (6H)

Consistent performance in high‑strength materials

The combination of HSS‑Co substrate and a robust cutting geometry is designed to cope with steels that exceed 1000 N/mm² tensile strength, delivering longer tool life and fewer interruptions in production. The cobalt‑alloyed high‑speed steel increases red hardness and wear resistance, which translates into reduced tool changes and improved process efficiency. As a result, cycle times remain predictable and machine utilisation increases without sacrificing thread quality.

Accurate thread form to recognised standards

Manufactured to DIN 371C and complying with DIN 13 sheet 1, this threading tool produces metric ISO threads to the ISO2 (6H) tolerance field, ensuring interchangeability and reliable assembly. The flank relief ground into the tool flanks improves thread profile fidelity and reduces burr formation, which simplifies downstream operations and inspection. Precision tolerances support automated assembly and quality control regimes with repeatable outcomes.

Geometry optimised for blind‑hole tapping and chip control

The 40° spiral flute with right‑hand helix actively evacuates chips from blind holes, lowering the risk of chip nesting and tap breakage. Flank relief and a defined form C, type H geometry combine to reduce cutting forces and enhance surface finish. The small 6 mm shank provides compatibility with standard collets and tapping holders while the Rotring marker allows quick visual identification on the tool rack, streamlining workshop logistics.

Integration into production and handling benefits

Designed as a machine tap, the tool fits conventional tapping heads and CNC tapping arrangements, enabling immediate integration into existing workflows. The tool’s construction and coating choices focus on stable cutting under interrupted feeds typical of blind‑hole operations, which supports predictable maintenance intervals and inventory planning. Clear material suitability information reduces setup risk and helps maintain traceable production parameters.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap M5 x 0.8 mm (SKU 2000867285NW) is specified for difficult‑to‑machine steels and is designed to handle materials with tensile strength above 1000 N/mm² thanks to its HSS‑Co construction.

Can the tap be used for through holes as well as blind holes?
Although optimised for blind holes via the 40° spiral flute, the machine tap may also be used in through‑hole applications where the flute geometry supports chip evacuation; the tool maintains ISO‑accurate thread form in both cases.

How does the 40° spiral flute improve productivity?
The 40° spiral flute actively removes chips from the cutting zone in blind‑hole tapping, reducing the risk of chip jamming and tap breakage, which enhances process reliability and lowers downtime.

What thread quality can be expected from this tool?
Threads produced meet DIN 13 sheet 1 requirements with tolerance ISO2 (6H), delivering repeatable, assembly‑ready internal threads suitable for standard fasteners and mechanical joints.

Which shank fitting is required for this tap?
The tool features a 6 mm shank and is compatible with standard collets and tapping holders that accept a 6 mm shank diameter, enabling straightforward integration into typical machine setups.
