TECWERK M12 x 1.75 mm HSS‑Co Machine Tap (DIN 376C) — Right‑hand spiral, ISO 6H tolerance

A TECWERK M12 x 1.75 mm HSS‑Co machine tap designed for producing ISO metric threads in blind holes, optimised for use in steels up to approximately 900 N/mm².

• HSS‑Co composition for extended tool life
• Right‑hand spiral 40° for blind holes
• ISO metric thread M12 x 1.75, tolerance 6H
• 9 mm shank for secure machine mounting

Consistent, high‑precision threads for demanding production

The combination of a DIN 376C geometry and ISO 6H tolerance ensures consistently accurate thread forms, reducing rework and assembly issues. Constructed from HSS‑Co, the tool offers elevated hot hardness and wear resistance, which maintains cutting geometry longer under cyclic loads. The flank relief produced by ground flanks minimises friction and supports superior surface finish on the internal thread. For workshops and production lines where repeatability matters, this tap delivers measurable improvements in first‑pass yield and reduces downstream sorting and quality checks.

Faster, safer blind‑hole tapping with spiral geometry

A 40° right‑hand spiral evacuates chips toward the shank, making the tap particularly suited to blind‑hole operations. Removing chips reliably lowers the risk of tap breakage and shortens cycle times, improving throughput in serial machining. The tool’s geometry and material pairing are calibrated for steels with tensile strengths up to ~900 N/mm², offering a balance between cutting performance and tool life. Where internal chip control is critical, this design reduces machine downtime and the need for frequent tool extraction, which supports a more efficient production rhythm.

Practical handling and compatibility on common machines

The generous 9 mm shank diameter facilitates stable clamping in tool holders and collets, enabling accurate concentricity and reduced vibration. The tap’s Form C profile and thread pitch match established ISO thread standards, simplifying integration into existing tooling sets and quality procedures. Operators benefit from predictable cutting forces and straightforward setup; the tool is suitable for common tapping heads and machining centres that accept DIN‑standard machine taps. Clear specification and robust construction translate into fewer surprises at setup and predictable performance across batches.

FAQ

What materials is this tap suitable for? The TECWERK M12 x 1.75 mm HSS‑Co machine tap is specified for use in steels up to approximately 900 N/mm² tensile strength and is optimised for common steel grades.

Can this tap be used for blind holes only? While the tool is optimised for blind‑hole applications thanks to its 40° spiral, it can also be used in through‑holes if chip evacuation and process parameters are adjusted accordingly.

What does the tolerance ISO2 (6H) indicate? Tolerance ISO2 (6H) denotes a standardised internal thread tolerance class offering a close fit suitable for general engineering assemblies and consistent interchangeability.

Is the shank suitable for standard machining setups? The 9 mm shank allows secure clamping in common collets and holders, supporting stable operation on tapping heads and machining centres compatible with DIN machine taps.

How does the HSS‑Co composition improve performance? HSS‑Co increases red hardness and wear resistance under elevated temperatures, which preserves cutting geometry over longer runs and contributes to improved tool life.
