Machine tap DIN 374C MF 6×0.75 mm HSS‑Co 6H by TECWERK — Cobalt HSS, Form C, 40° helix

A Machine tap DIN 374C MF 6×0.75 mm HSS‑Co 6H engineered for producing precise metric fine threads in blind holes and suited for steels up to approximately 1000 N/mm².

• Cobalt HSS for extended life and heat resistance
• Form C geometry with 40° right‑hand helix
• Metric fine thread MF, tolerance 6H
• Optimised for blind‑hole tapping in steels

Consistent metric fine threads for assembly reliability

Produced to the DIN 13 metric fine‑thread standard, this machine tap delivers reproducible thread form and the specified tolerance 6H to ensure correct fit in mating parts. The fine‑pitch MF 6×0.75 mm specification is ideal where compact fastenings and high clamping precision are required. As a result, assemblies benefit from reduced play and improved load distribution; the tool is particularly useful when repeatable quality is essential in serial production environments.

Robust cutting performance and controlled chip evacuation

The tool’s HSS‑Co composition adds cobalt to high‑speed steel, increasing hot‑hardness and wear resistance for extended cutting intervals. Combined with Form C geometry and a 40° right‑hand helix, the design promotes effective chip evacuation during blind‑hole machining, reducing the risk of chip packing and tap breakage. The shaft diameter of 4.5 mm provides a compact drive connection for automatic tapping heads and machines, while the partially relieved flanks improve cutting engagement and surface finish.

Seamless integration into machine workflows

Engineered for machine tapping, this product supports reliable cycle times and predictable tool change planning in production lines and workshop machinery. Its suitability for blind holes and for machining steels up to around 1000 N/mm², as well as temperguss and long‑chipping non‑ferrous metals, makes it a versatile choice across maintenance, repair and manufacturing tasks. For specification checks or to confirm compatibility with a given tapping unit, Metav’s technical advisors are available to provide application guidance and data clarification.

FAQ

Can this tap be used for blind holes?
Yes. The TECWERK machine tap is designed specifically for blind‑hole threading and features a 40° helix and flank relief to aid chip evacuation in such applications.

Which materials is the tap suitable for?
The tap is suitable for steels up to approximately 1000 N/mm², temperguss and long‑chipping non‑ferrous metals as stated for the TECWERK machine tap.

What makes HSS‑Co advantageous for this tool?
The cobalt‑enriched high‑speed steel in the tool increases hot‑hardness and wear resistance, extending tool life and maintaining cutting performance under higher temperatures.

What tolerance and thread standard does it meet?
Threads are produced to the DIN 13 metric fine‑thread standard with a tolerance of 6H for consistent assembly fit.

What is the shank diameter and how does it interface with tapping machines?
The shank diameter is 4.5 mm, allowing secure mounting in automatic tapping heads and machine tool holders adapted for smaller shank sizes.
