M12x1.75mm Machine Tap DIN 376C HSS-Co TiCN Coated ISO2 (6H) for Blind Holes, 9mm Shank - TECWERK

Benefit from the combination of a TiCN coating, a HSS‑Co substrate and ISO2 (6H) tolerance for dependable M12×1.75 blind‑hole threading; order the tap directly via Metav Werkzeuge or consult the technical advisers for specification support.

Machine tap DIN 376C VA M12×1.75 HSS‑Co TiCN (6H) — TECWERK

The Machine tap DIN 376C VA M12×1.75 is a right‑hand spiral machine tap engineered for producing metric ISO blind threads in corrosion‑ and heat‑resistant steels.

• HSS‑Co substrate for high wear resistance
• TiCN coating for extended tool life
• Right‑hand 40° spiral for efficient chip evacuation
• ISO2 (6H) tolerance for precise thread fit

Reliable thread quality for production runs

The DIN‑compliant design ensures repeatable results in series production. With ISO2 (6H) tolerance and conformity to DIN 376C and DIN 13 sheet 1, the tool produces consistent M12×1.75 threads with reduced rework rates. The combination of a defined helix geometry and ground flanks leads to stable cutting behaviour, which directly supports process reliability and predictable assembly fits in manufactured components.

Superior wear resistance for demanding materials

Constructed on an HSS‑Co substrate and finished with a TiCN coating, the tap resists abrasion and maintains cutting edges longer in high‑strength and stainless alloy steels. The specification indicates suitability for corrosion‑, acid‑ and heat‑resistant steels up to 1000 N/mm² tensile strength, so the tool is appropriate where thermal and chemical resistance of the workpiece material increases tool stress. The nitrided‑like surface of the coating reduces friction, improving tool life and lowering the frequency of replacements.

Efficient chip control and robust shank for secure machining

A 40° right‑hand spiral optimises chip evacuation in blind‑hole applications, preventing chip packing and supporting uninterrupted cycles. The tool features flank relief grinding to reduce cutting forces and a shank Ø 9 mm for stable clamping in standard toolholders, delivering higher process stability and minimised vibration. These design choices enhance surface finish and thread accuracy while enabling faster cycle times in both manual and CNC tapping operations.
