M20x2.5mm Machine Tap DIN 376C HSS-Co 6H Form C Right-Hand Flute 40° For Blind Holes, 16mm Shank - TECWERK

The combination of HSS‑Co construction, DIN 376C geometry and a 40° right‑hand spiral delivers reliable thread formation in high‑tensile steels; benefit from consistent ISO‑class tolerance and stable machine mounting for an uninterrupted production flow — order via Metav Werkzeuge or consult our specialists for application guidance.

Machine thread tap DIN 376C H M20×2.5mm HSS‑Co 6H TECWERK — cobalt‑alloyed HSS, M20×2.5

The Machine thread tap DIN 376C H M20×2.5mm HSS‑Co 6H TECWERK is a precision machine tap designed for producing metric ISO threads in demanding materials, optimised for blind‑hole applications and industrial machine use

• Cobalt‑alloyed HSS for high wear resistance
• DIN 376C geometry for repeatable precision
• Right‑hand 40° spiral for efficient chip evacuation
• Shank Ø 16 mm for stable machine mounting

Consistent thread quality in demanding materials

The TECWERK M20×2.5 machine tap is engineered to produce metric ISO threads to ISO2 (6H) tolerance with high reproducibility. Constructed from HSS‑Co (cobalt‑alloyed high‑speed steel), the tool resists heat and wear when machining tough alloys. The combination of DIN 376C geometry and flank relief grinding results in a defined cutting edge that reduces dimensional scatter, which supports predictable assembly fit and minimises rework in serial production.

Reliable chip control reduces downtime and rework

A 40° right‑hand spiral promotes controlled chip formation and evacuation, an advantage when working in blind holes where chip clearance is restricted. The spiral geometry, together with flanks that are relief‑ground, prevents chips from jamming and lowers the risk of tap breakage. For process planners this means fewer interrupted cycles and a higher first‑pass yield, translating into measurable time savings on high‑volume jobs.

Stable machine integration and straightforward setup

The tap's shank Ø 16 mm provides robust clamping in standard toolholders and collets, supporting concentricity and torque transmission under load. Classified as Form C / Type H, the tool fits conventional machine tapping fixtures and is compatible with common thread‑cutting cycles. Clear marking (Rotring) on the shank speeds identification on the tool board and simplifies changeovers, aiding lean production workflows where setup time must be minimised.

Traceable standards and suitability for high‑strength steels

Manufactured to match DIN 13 Part 1 and the DIN 376C family, the tap offers documented geometry and tolerance conformity for quality assurance routines. It is specifically suitable for machining steels with tensile strength above 1,000 N/mm², making it appropriate for structural and heat‑treated components where thread integrity is critical. Specification consistency supports inspection regimes and reduces uncertainty during qualification of incoming tooling.
