TECWERK MF10 x 1.25 mm Threading Die, Form B — HSS, 6g

The TECWERK MF10 x 1.25 mm threading die is a closed, pre-slotted tool for cutting metric fine external threads to DIN 13 MF and DIN EN 22568 standards, suitable for general engineering use.

• HSS cutting material, DIN EN 22568
• Metric fine thread MF10 x 1.25 mm
• Tolerance field 6g for precise fits
• Suitable for steels up to ~800 N/mm²

Precision cutting for repeatable external threads

Built to industry standards, this threading die combines HSS cutting material with DIN-compliant geometry to deliver reproducible results on metric fine threads. The specification to DIN EN 22568 and DIN 13 MF means thread form and pitch conform to recognised tolerances, reducing rework and inspection time in production. The 6g tolerance field offers a reliable medium-fit class for general mechanical assemblies, which simplifies selection when standardised interfacing with bolts and components is required.

Consistent performance on medium-strength steels

Engineered for use on steels up to approximately 800 N/mm², the tool’s HSS composition balances hardness and toughness for stable cutting performance in workshop environments. The closed, pre-slotted Form B design produces full-profile threads while the pre-slotted relief assists chip control during cutting, lowering the risk of jamming when machining long runs or interrupted surfaces. This combination supports higher first-pass success rates and steady throughput on component batches.

Seamless integration into workshop workflows

Conforming to ISO metric fine-thread practice, the die fits common holders and thread-cutting fixtures used across maintenance and production shops. The modest height of 11 mm keeps the tool compact for use in confined setups and chaser holders. Specifying a DIN-based die streamlines procurement and quality assurance, while durable HSS construction extends service intervals compared with lower-grade materials, contributing to a predictable maintenance schedule for the tool crib.

Practical guidance for reliable results

For most applications, progressive engagement with adequate lubrication and controlled feeds will extend life and improve surface finish. The closed Form B requires attention to chip evacuation—use of suitable cutting fluid and periodic clearing of the pre-slot encourages uninterrupted cutting. The tool’s designation for metric fine threads means matched counterparts should be chosen with the same 6g class to secure the intended fit and function in assemblies.

FAQ

What materials can this die cut?
The TECWERK MF10 x 1.25 mm die is specified for use on steels up to approximately 800 N/mm² and is suitable for general engineering steels.

Is the thread form standardised?
Yes, the tool conforms to DIN EN 22568 and DIN 13 MF, producing ISO metric fine-thread geometry for compatible mating parts.

How does the pre-slotted Form B affect use?
The pre-slot assists chip evacuation during cutting while the closed Form B yields a full-profile external thread; regular clearing of the slot and appropriate lubricant are recommended.

Can the die be used in common holders?
The die’s dimensions and form are compatible with standard die holders for external threading used in maintenance and production workshops.

What tolerance does the die produce and what does that mean?
The die produces a 6g tolerance field, a medium external thread fit commonly used in mechanical assemblies for reliable engagement with standard mating threads.
