Round die Form B M4×0.7 HSS, tolerance 6g — TECWERK

A round die Form B M4×0.7 HSS 6g TECWERK designed for cutting external metric ISO threads in steels up to approximately 800 N/mm², combining a compact 5 mm height with DIN EN 22568 conformity.

• HSS cutting material for durability
• Metric ISO thread M4×0.7, tolerance 6g
• Closed, pre-slotted Form B for stability
• Suitable for steels up to 800 N/mm² tensile

Consistent thread quality for production use

The die’s HSS construction and conformity to DIN EN 22568 ensure consistent thread quality even under repeated use. The combination of hardened high-speed steel and the closed, pre-slotted Form B geometry reduces vibration and radial run-out during cutting, which directly improves dimensional repeatability and surface finish of the external threads. For production-oriented workshops, this translates into fewer reworks and a steadier process yield when machining metric ISO threads.

Predictable performance on engineering steels

Designed for materials with tensile strengths up to 800 N/mm², the tool handles a broad range of common engineering steels without premature wear. The tolerance 6g specification gives a clear fit class for external threads and supports reproducible mating with standard internal threads. Because the die is pre-slotted, swarf evacuation is improved compared with fully closed dies, offering a balance between strength and chip control that benefits both manual and machine-assisted threading operations.

Compact form factor with straightforward handling

With a height of 5 mm and a compact circular profile, the die integrates easily into existing die stocks and holders. The modest size aids accessibility in confined workspaces and simplifies tool changeover in set-ups that require frequent thread sizes. Its metric ISO thread format follows DIN 13 standards, so interchangeability with conventional tooling and fasteners is straightforward, reducing procurement complexity for maintenance and production teams.

Clear technical standards and workshop reliability

The tool’s adherence to recognised standards and use of HSS cutting material provide a reliable baseline for planning tooling life and maintenance intervals. The Form B design contributes to enhanced stability during thread cutting, which is especially valuable in repetitive tasks where maintaining thread geometry is crucial. For workshops looking to centralise tool sourcing, this die complements a standardised tooling inventory and supports consistent assembly outcomes.

FAQ

What materials can this die machine this die reliably cut?
This TECWERK round die is specified for steels up to approximately 800 N/mm² tensile strength and is suitable for typical engineering steel applications within that range.

Is the thread tolerance suitable for standard bolt fits?
Yes, the die produces an external thread with tolerance 6g, compatible with standard internal threads and commonly used fit classes for general assembly.

Can the die be used in a machine holder or is it for hand use only?
The compact Form B die is compatible with standard die holders and can be used both manually and in appropriate machine-assisted holders, subject to the holder’s specifications.

How does the pre-slotted design affect performance?
The pre-slotted configuration improves chip evacuation while maintaining structural integrity, offering a compromise between fully open and closed designs for cleaner cuts and reduced jamming.
