Threading die Form B M30×3.5 mm HSS 6g (TECWERK) — metric ISO die for workshop threading

A Threading die Form B M30×3.5 mm HSS 6g (TECWERK) designed for accurate metric ISO thread cutting in medium-strength steels, suitable for production and repair tasks

• Metric ISO thread M30×3.5 mm
• High-speed steel (HSS) cutting material
• Closed, pre-slotted design for chip control
• Tolerance field 6g for ISO-fit threads

Precision threads that match ISO standards and reduce rework

The combination of HSS cutting material and an ISO-compliant geometry ensures repeatable results when producing M30×3.5 mm threads. Conformity with DIN EN 22568 and the metric thread form defined in DIN 13 provides an objective basis for quality control and interchangeability. The specified 6g tolerance field delivers a standard clearance fit that reduces assembly issues and minimises post-process correction. For workshops and small-scale production, this equates to fewer rejects and more predictable assembly behaviour, supporting a steady workflow and lower overall processing time.

Stable cutting action for consistent surface finish and chip control

The closed, pre-slotted format of Form B combines dimensional stability with an integrated chip-splitting capability. The 25 mm section height contributes to rigid engagement and maintains concentricity during the cut, helping to avoid chatter and imperfect threads. This constructive design reduces the likelihood of partial thread forming and improves the surface finish, which is advantageous where thread engagement and sealing behaviour are critical. The pre-slotted form also eases chip evacuation compared with fully closed dies, offering a balance between strength and swarf management.

Material compatibility and recommended applications

Specified for machining steels up to approximately 800 N/mm², the die is appropriate for common structural and engineering steels used in mechanical assemblies and maintenance operations. The HSS cutting material provides both toughness and wear resistance under moderate feeds and typical cutting speeds used for metric threading. Typical use cases include repair work, component assembly, in-house maintenance, and small-batch production where standard metric ISO threads are required. The technical specification supports informed tool selection for applications where repeatable thread geometry and ISO conformity are priorities.

Simple handling and predictable service life

High-speed steel offers a known balance between performance and maintainability: light resharpening restores cutting edges and routine lubrication extends tool life. The compact design facilitates quick mounting in standard die stocks or holders and the robust Form B profile supports repeated use in workshop environments. Regular use of appropriate cutting lubricant, controlled feed rates and correct alignment with the mating part will extend service intervals and preserve thread quality. Safety and handling remain straightforward thanks to the die’s stable geometry and conventional mounting dimensions.

FAQ

What thread standard does the die follow?
The threading die follows metric ISO geometry as referenced in DIN 13 and additional specification in DIN EN 22568, ensuring compatibility with ISO-threaded components.

Which materials can be machined with this die?
The TECWERK Form B die is specified for use on steels up to approximately 800 N/mm² tensile strength and is manufactured from HSS for durability in those applications.

Is the die suitable for production or repair work?
The die’s closed, pre-slotted design and ISO-compliant tolerance 6g make it suitable for both repair and small-batch production where consistent thread quality is required.

What maintenance is recommended to preserve cutting life?
Use appropriate cutting lubricant, maintain correct alignment in the die stock and inspect the HSS cutting edges; light resharpening is possible to restore performance where applicable.
