12mm Machine Tap DIN 374C Universal MF12x1.5 HSS-Co Vapourised 6H For Blind Holes, 9mm Shank - TECWERK

Take advantage of the combination of cobalt HSS construction and a vapourised surface with a 40° right‑hand spiral for reliable blind‑hole tapping and consistent ISO‑class thread quality; order directly via Metav Werkzeuge or consult the technical advisors for application support.

TECWERK machine tap DIN 374C — M12 x 1.5, HSS‑Co, vapourised

The TECWERK machine tap DIN 374C M12 x 1.5 is a universal Type C machine tap designed for producing metric fine threads in blind holes across a broad range of engineering materials.

• Cobalt HSS for high wear resistance
• Vapourised coating and green ring identification
• Right‑hand spiral 40° for blind hole evacuation
• ISO2 (6H) tolerance for precision threads

Consistent thread quality for industrial use

The HSS‑Co construction delivers elevated hot‑hardness and wear resistance compared with conventional high‑speed steel, enabling longer life under demanding conditions. Combined with the vapourised coating, friction at the cutting edges is reduced, which helps to maintain thread form and surface finish on fine metric threads such as M12 x 1.5. This results in fewer rejects and less frequent reworking, supporting a more efficient production flow and predictable tool costs for the workshop.

Reliable blind‑hole performance and chip control

The 40° right‑hand spiral and flank relief are engineered for blind‑hole tapping: the spiral helms chips away from the cutting edges and towards the shank, reducing the risk of chip jamming deep in the workpiece. The combination of spiral geometry and vapourised surface reduces cutting forces and improves evacuation, which protects both the thread form and the machine spindle. Identification via the green ring simplifies tool selection in mixed tool sets and speeds up changeover, supporting uptime and operator confidence.

Precision standards and workshop compatibility

Manufactured to DIN 374C (Form C) and conforming to DIN 13 thread specifications with ISO2 (6H) tolerance, the tool produces threads that meet recognised fit and interchangeability requirements. A shank diameter of 9 mm ensures compatibility with standard collets and holders commonly found in modern machining centres. The universal Type C geometry makes this tap suitable for steel, stainless steels, spheroidal graphite cast iron and non‑ferrous metals, offering versatility for maintenance shops and production environments alike.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap DIN 374C M12 x 1.5 is suitable for steel, stainless steels, spheroidal graphite cast iron and various non‑ferrous metals, benefiting from the HSS‑Co composition and vapourised surface.

Is the tap designed for blind holes or through holes?
The tap is a Form C Type designed specifically for blind‑hole applications; the 40° right‑hand spiral assists chip evacuation away from the cutting edge in blind holes.

What tolerance and standard does the tap comply with?
Threads produced meet DIN 13 with a tolerance field ISO2 (6H), providing precision fits for metric fine threads.

What is the shank size and how is it held?
The tap has a 9 mm shank diameter, suitable for standard collets and holders used in machine tool setups.

How does the vapourised coating benefit machining?
The vapourised coating reduces friction and heat at the cutting edge, which improves tool life and thread surface quality, especially under higher cutting speeds or intermittent production cycles.
