Machine tap DIN 374C MF 30x2 mm HSS‑Co 6H — TECWERK, right‑hand spiral 40°

The Machine Tap DIN 374C MF 30x2 mm HSS‑Co 6H is a precision metric fine‑thread tap designed for producing blind threads in medium‑to‑high‑strength steels, temper cast iron and long‑chipping non‑ferrous metals.

• DIN 374C Form C metric fine thread
• HSS‑Co for high wear resistance
• Right‑hand spiral 40° for blind holes
• Shaft Ø 22 mm for secure clamping

Achieve consistently accurate fine threads with standardised tolerances

Built to DIN 374C and matching the DIN 13 metric ISO fine‑thread system, this tap delivers repeatable thread geometry with a 6H tolerance. The standardised dimensions reduce assembly issues and rework by ensuring interchangeability with mating parts. For production environments where thread fit and functional reliability are critical, the combination of metric fine‑pitch specification MF 30x2 mm and precise tolerance control supports predictable assembly outcomes and improved first‑pass yield.

Durable cobalt high‑speed steel construction lowers tooling costs

Made from HSS‑Co, the tool provides increased hardness and heat resistance compared with standard high‑speed steel, improving performance when cutting harder materials. The cobalt alloy increases service life under elevated temperatures and sustained cutting loads, which translates into fewer tool changes and reduced machine downtime. When machining steels up to approximately 1000 N/mm², the material choice helps maintain sharp cutting edges and consistent surface finish, offering a cost‑effective balance between tool life and cutting performance.

Optimised spiral and flank geometry for blind‑hole tapping

The right‑hand spiral 40° and flank relief grinding are engineered to evacuate chips efficiently when forming blind threads, minimising chip packing and reducing the risk of thread damage. This geometry guides chips back into the flutes rather than forcing them deeper into the hole, so the thread form remains intact and the tapping cycle is more robust. Where blind holes are common, the spiral design enhances process stability and reduces scrap rates, improving overall production reliability.

Machine compatibility and secure clamping for stable machining

A shaft diameter of 22 mm provides a robust connection with standard machine holders, ensuring stable torque transmission and reduced run‑out during tapping. Classified as Form C, the tool is suitable for standard machine tapping operations and integrates readily into existing tapping workflows. The combination of secure clamping, standard form factor and compliance with ISO metric thread standards facilitates straightforward machine setup and consistent thread quality across batches.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap is suitable for steels up to approx. 1000 N/mm², temper cast iron and long‑chipping non‑ferrous metals, as indicated by the HSS‑Co tool specification.

Is this tap suitable for blind‑hole threading?
Yes, the right‑hand spiral 40° and flank relief grinding are specifically designed to evacuate chips during blind‑hole tapping and to protect the thread form.

What does the tolerance 6H mean for assembly?
Tolerance 6H denotes a standard internal thread tolerance that ensures a reliable fit with corresponding external threads, supporting consistent assembly quality.

How does the HSS‑Co material affect tool life?
The cobalt‑alloy HSS‑Co increases heat resistance and hardness, extending tool life under higher cutting temperatures and when machining tougher materials.

What size of machine holder is recommended?
The tap features a shaft diameter of 22 mm, which is intended for secure clamping in compatible machine holders to reduce run‑out and ensure stable tapping.
