Machine Tap M12 x 1.75 mm (DIN 376C) – HSS‑Co, 6H – TECWERK

A Machine Tap M12 x 1.75 mm (DIN 376C) designed for producing metric ISO blind threads in high‑strength steels and for use on machine tapping units.

• HSS‑Co for higher wear resistance
• Right‑hand spiral 40° for effective chip evacuation
• For blind holes in hard‑to‑machine steels >1000 N/mm²
• Tolerance ISO2 (6H) metric thread, shank Ø 9 mm

Accurate threads that fit first time

The tap is manufactured to DIN 376C and produces metric ISO threads to the ISO2 (6H) tolerance class, ensuring consistent fit with standard components. This accuracy reduces rework and scrap by guaranteeing compatibility with bolts and mating parts. The standardised geometry and tolerance control mean predictable assembly behaviour, which supports lean production and shortens quality inspection cycles.

Geometry engineered for safe chip control

Optimised cutting and relief geometry with a 40° right‑hand spiral and flank relief minimise the risk of chip packing in blind holes. The spiral lead actively directs chips back out of the hole, reducing torque peaks and the likelihood of breakage in deep or blind threads. For machine‑based tapping operations, this results in fewer interruptions, increased spindle uptime and more consistent cycle times.

Material selection for demanding applications

Made from HSS‑Co, the tool combines hardness with red hardness retention for extended tool life when working steels with tensile strengths above 1000 N/mm². The robust construction and shank Ø 9 mm provide secure clamping in machining holders, improving concentricity and reducing vibration. The combination of material and design lowers tooling costs per thread by extending service intervals and maintaining cutting performance under high loads.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is made of HSS‑Co and is specified for machining hard‑to‑machine steels with tensile strengths above 1000 N/mm²; it also performs on common steels and alloyed materials when appropriate cutting data are applied.

Is the tap suitable for blind holes and through holes?
Yes, the tool geometry with a 40° right‑hand spiral is optimised for blind threads, promoting chip evacuation; it can also be used for through threads depending on the clamping and machine setup.

Which tolerance and thread standard does the tool meet?
Threads produced correspond to metric ISO standards to ISO2 (6H) tolerance and comply with DIN 13 Sheet 1, ensuring compatibility with standard fasteners.

What are the shank and mounting details?
The tap features a shank Ø 9 mm, suitable for rigid tool holders on machine tapping spindles; secure clamping improves concentricity and service life.

Can the tap be used on automated tapping machines?
The design and right‑hand spiral support machine tapping applications; the HSS‑Co material and relieved flanks reduce the risk of breakage under automated cycle conditions.
