TECWERK MF6×0.75 HSS round die (Form B) — metric fine thread, 6g tolerance

A TECWERK MF6×0.75 HSS round die designed for cutting external metric fine threads to DIN specification in common workshop steels.

• HSS high-speed steel construction
• Metric fine thread MF6×0.75
• Tolerance field 6g, DIN 13 compliant
• Closed pre-slit Form B, 7 mm height

Accurate metric fine threads for consistent assemblies

The MF6×0.75 round die delivers metric ISO fine threads with a 6g tolerance that matches common assembly requirements. Conformity with DIN EN 22568 and DIN 13 MF ensures compatibility with standard components and diminishes the need for rework. The tool’s geometry is optimised for external threading tasks where a compact thread profile and predictable fit are required, supporting repeatable production results in small-batch and maintenance scenarios.

Durable HSS construction for extended service life

Manufactured from HSS (high-speed steel), the cutting material offers a balanced combination of hardness and toughness suitable for repetitive cutting operations. The substrate resists abrasive wear under typical workshop conditions, maintaining cutting edges longer than standard carbon-steel alternatives. This robustness contributes to lower downtime for tool changes and a reduced frequency of replacement, supporting efficient workshop planning and reliable throughput.

Stable Form B design for controlled machining

The Form B configuration features a closed, pre-slit design that stabilises the cutting action while accommodating chip flow. With a compact 7 mm height, the die provides a solid engagement length that reduces chatter and ensures a cleaner lead into the workpiece. The pre-slit relief assists chip evacuation and lowers the risk of seizure during interrupted cuts, resulting in more uniform surface finish and thread geometry on the finished external thread.

Application scope and material suitability

Specified for use in common steels, the tool is rated for materials up to approximately 800 N/mm² tensile strength, making it appropriate for a wide range of engineering steels encountered in maintenance and light production. The tool’s specification does not list specialised coatings; performance in softer non-ferrous materials will depend on cutting parameters and lubrication. For high-speed or abrasive applications, a review of cutting data and potential coated alternatives is recommended.

Integration into workshop workflows

The compact die fits established die holders and manual threading setups, supporting rapid replacement and straightforward handling. Its standardised thread form reduces inspection complexity and simplifies quality checks against existing gauges. For inventory rationalisation, keeping this metric fine die in stock can streamline repair tasks and short-run production where MF threads are regularly required.

Standards, traceability and quality expectations

Production to DIN EN 22568 and adherence to DIN 13 MF provide a clear standard basis for thread form, tolerance and interchangeability. The combination of standard conformity, HSS material and Form B configuration yields a reliable external-threading tool that aligns with common industrial expectations for repeatable fit and serviceability.

FAQ

What thread size and pitch does this die produce?
The TECWERK MF6×0.75 HSS round die produces a metric fine external thread with a size of MF6 and a pitch of 0.75 mm (MF6×0.75), matching DIN 13 MF specifications.

Which materials is the die suitable for?
This round die is specified for use with steels up to approximately 800 N/mm² tensile strength; suitability for other materials depends on cutting parameters and lubrication.

What does the 6g tolerance mean for assembly?
Tolerance 6g indicates the external thread class for the die, providing a standard clearance and fit for mating internal threads produced to compatible tolerance classes.

Is the die a slotted design and what is the benefit?
The tool is a closed pre-slit Form B die; the pre-slit profile assists chip control and reduces the likelihood of seizure, while maintaining a stable cutting engagement.

Which standards govern the thread form and production quality?
Production and thread form are aligned with DIN EN 22568 and DIN 13 MF, ensuring standardised thread geometry and interchangeability for metric fine threads.
