Maschinengewindebohrer DIN 371B M3x0,5mm HSS-Co 6H TECWERK — machine tap M3 × 0.5 mm, HSS‑Co, DIN 371B

The Maschinengewindebohrer DIN 371B M3x0,5mm HSS-Co 6H TECWERK is a precision machine tap intended for cutting metric ISO threads in medium‑strength steels and for through‑hole applications where a shearing chamfer improves chip evacuation

• HSS‑Co alloy for high wear resistance
• DIN 371B form B, straight fluted design
• ISO metric thread M3 × 0.5, tolerance 6H
• Suitable for steels up to 900 N/mm²

Consistent, measurable thread quality for production use

The cobalt‑alloy construction and standard‑compliant geometry deliver a reproducible thread form suitable for serial production. Built from HSS‑Co, the tool maintains cutting edge stability at elevated temperatures and under continuous use; combined with DIN 371B Form B geometry and the ISO2 (6H) tolerance class, this results in threads that meet common assembly requirements without additional post‑processing. For workshop planners and production engineers, the clear specification of M3 × 0.5 mm and the adherence to DIN 13 part 1 simplify process validation and inspection routines.

Broad application range with clear material limits

The tool is specified for machining steels up to 900 N/mm² tensile strength, making it suitable for mild and many alloy steels encountered in general engineering. This specification indicates the mechanical limits where cutting performance and tool life are optimised; when facing harder materials, a different grade or geometry should be selected. The combination of HSS‑Co material and straight flute geometry balances wear resistance and chip formation for conventional through‑hole tapping tasks.

Geometry and cutting edge features that speed up throughput

Form B and the straight fluted design, together with flanks honed for reduced burr, contribute to controllable chip flow and lower thread roughness. The integrated shearing chamfer for through threads is engineered to slice chips cleanly on exit, reducing the risk of thread distortion and minimising the need for secondary deburring. These details translate into fewer rejects and shorter cycle times on automatic or semi‑automatic tapping machines, delivering tangible efficiency gains in production environments.

Practical handling, mounting and traceable specification

A clearly specified shaft diameter of 3.5 mm supports secure mounting in standard holders and collets, aiding quick tool changes and reliable runout control. Supplied as a single unit, the tap allows straightforward stock management for small batch production or toolroom use. As the tool conforms to established standards and is traceable via SKU 2000867243NW, integration into quality systems and material documentation is uncomplicated. This TECWERK tap is therefore a pragmatic choice where predictable performance and compatibility with existing equipment matter.

FAQ

Which materials can be machined with this tap?
The Maschinengewindebohrer DIN 371B M3x0,5mm HSS‑Co 6H TECWERK is specified for use in steels up to approximately 900 N/mm² tensile strength and is optimised for those material classes.

Is the tap intended for through holes or blind holes?
The tool incorporates a shearing chamfer for through threads, so the Maschinengewindebohrer DIN 371B M3x0,5mm HSS‑Co 6H TECWERK is primarily intended for through‑hole applications.

What thread tolerance and standard does the tap produce?
Threads produced conform to metric ISO specifications in accordance with DIN 13 part 1, with a tolerance class of ISO2 (6H) as delivered by the Maschinengewindebohrer DIN 371B M3x0,5mm HSS‑Co 6H TECWERK.

What holder or shank is required to use this tap?
The tap has a shaft diameter of 3.5 mm; it mounts in holders or collets compatible with a 3.5 mm shank for secure clamping and reduced runout when using the Maschinengewindebohrer DIN 371B M3x0,5mm HSS‑Co 6H TECWERK.

Is a coating applied to the tap?
The tool is made from HSS‑Co base material; no additional coating is specified for the Maschinengewindebohrer DIN 371B M3x0,5mm HSS‑Co 6H TECWERK in the supplied data.
