M5x0.8mm Machine Tap DIN 371B H, HSS-Co 6H Straight Flute, Shell Recess - TECWERK

Take advantage of the combination of cobalt-alloy HSS and a precision ISO2 (6H) tolerance for consistent, production-ready threads; the robust geometry reduces rework and keeps tool changes to a minimum. Order this machine tap via Metav Werkzeuge or consult the team for specification matching.

TECWERK Machine tap DIN 371B H M5 x 0.8 mm — HSS‑Co, ISO2 (6H)

A TECWERK M5 x 0.8 machine tap designed for creating accurate metric ISO threads in through-holes, optimised for challenging steels and series production.

• Cobalt-alloy HSS for high wear resistance
• Form B, straight flutes with honed flanks
• DIN 13 / ISO metric thread M5 x 0.8
• Tolerance field ISO2 (6H) for precision fits
• For through threads in steels >1000 N/mm²

Consistent thread quality for demanding production

This machine tap, crafted in HSS‑Co, delivers a balance of wear resistance and toughness needed when cutting into high-strength materials. The cobalt-alloy composition maintains cutting-edge stability at elevated temperatures, which reduces flank wear and extends service life in repetitive operations. With the specified chamfer for through threads, the cutting lead ensures predictable chip formation and lowers the risk of thread distortion, translating into fewer rejects and less downstream rework.

Tight tolerances for reliable assembly performance

Compliance with DIN 13 and the ISO2 (6H) tolerance field ensures that each thread meets established fit and interchangeability standards. The tolerance specification supports consistent assembly behaviour across batches, which is essential for production lines and maintenance stocks where parts must mate reliably without trial fits. Choosing a tool with defined tolerance performance reduces variability and supports quality control processes.

Geometry engineered to reduce downtime

The combination of Form B geometry, straight flutes and honed flanks improves chip control and surface finish on the thread flanks. This geometry lowers cutting forces and minimises the tendency for chips to clog, particularly when machining tougher alloys. The visible red ring marking aids rapid identification on the tool trolley, while the solid shank design ensures secure seating in collets or holders, keeping runout low and helping to preserve both tap and spindle life.

Practical integration into workshop workflows

With a shank Ø 6 mm, the tap fits standard toolholders and is straightforward to integrate into hand tapping fixtures or automated tapping spindles. Designed for through-hole threading in steels with tensile strengths above 1000 N/mm², it reduces the need for multiple specialised tools, simplifying inventory. Combined with consistent geometry and material choice, this leads to fewer tool changes, more predictable cycle times and a measurable improvement in overall throughput.

FAQ

Is this tap suitable for through-hole threading in high-strength steels?
Yes. The TECWERK machine tap M5 x 0.8 mm in HSS‑Co is specified for through threads and is suitable for steels with tensile strength above 1000 N/mm².

What tolerance and standard does the tap meet?
The tool conforms to DIN 13 Blatt 1 and is manufactured to the ISO2 (6H) tolerance field, providing consistent fit for standard metric assemblies.

Which holder or shank size is required for use?
The tap has a shank Ø 6 mm, making it compatible with common collets and holders designed for 6 mm shanks.

What advantage do honed flanks offer for thread quality?
Honed flanks reduce burr formation and improve the surface finish of the thread flanks, which decreases the need for post-threading finishing and improves assembly behaviour.

Can this tap be used in automated tapping spindles?
Yes. The robust shank and geometry are suited to both manual fixtures and automated spindles for series production; ensure correct spindle runout and clamping to preserve thread accuracy
