TECWERK Thread Former M3 (Form C) — HSS-Co, TiN-coated

The TECWERK Thread Former M3 (Form C) is a TiN-coated, straight-fluted thread former designed for metric ISO regular threads in both through and blind hole applications.

• M3 thread, Form C, TiN coating
• HSS-Co for improved wear resistance
• Straight flutes for reliable chip control
• Tolerance 6HX for consistent thread fit

Faster, more economical thread production with forming technology

A forming tap replaces cutting by displacing material to create threads, which eliminates chip production and reduces secondary cleaning. The combination of HSS-Co substrate and TiN surface treatment increases wear resistance and lowers friction, resulting in fewer tool changes and reduced downtime. For small-batch and series production, this approach delivers a clear cost-benefit: higher throughput and less rework compared with conventional cutting taps. The tool’s geometry supports stable forming even under varying feed conditions, helping to shorten cycle times while maintaining surface integrity.

Reliable thread quality for through and blind holes

The straight-fluted, flank-ground design provides precise material flow and improved thread profile formation, which is particularly important for shallow or blind holes. With a thread length of 11 mm and a 3.5 mm shank, the tool provides sufficient engagement for full-form M3 threads without overloading the workpiece. The specified 6HX tolerance supports a predictable fit for mating parts, reducing the need for rework or thread gauging. This makes the component assembly process smoother and more predictable in batch production environments.

Broad material compatibility and process robustness

This forming tool is intended for non-ferrous metals and steels that exhibit at least 10% elongation, enabling secure thread formation in common workshop materials. The HSS-Co construction gives the core toughness required for interrupted feeds and mixed materials, while the TiN layer decreases adhesion and heat build-up during forming. Together, these attributes extend tool life and support consistent output across multiple workpieces, which translates into lower cost per thread and improved production reliability.

Practical integration and quality assurance in the workshop

The metric ISO regular thread geometry and form designation simplify documentation and quality control. Using a form tap with the described features helps avoid chip evacuation issues and reduces the need for complex extraction systems. For process set-up, ensure correct pilot hole dimensions and secure clamping to avoid part movement during forming. If additional guidance is required for hole preparation or process parameters, Metav Werkzeuge offers technical advice and product matching to existing workflows, helping to integrate this tool into established production lines with minimal disruption.

FAQ

What materials is this thread former suitable for?
The TECWERK thread former is intended for non-ferrous metals and steels with at least 10% elongation, meeting the material requirements for reliable forming.

How does a forming tap differ from a cutting tap?
A forming tap creates threads by displacing material rather than cutting it; the TECWERK forming tool therefore produces no chips and typically improves surface finish and thread strength.

Is the tolerance compatible with standard fasteners?
Yes, the 6HX tolerance specified for the tool provides a predictable fit for standard metric ISO threads and helps ensure consistent assembly behaviour.

Can the tool be used in blind holes as well as through holes?
The tool’s geometry is suitable for both through and blind hole applications, offering controlled material flow and reduced risk of incomplete threads.

What are the key dimensional specifications to consider for set-up?
Key dimensions include the M3 thread size, 11 mm thread length and 3.5 mm shank diameter; these should be matched to the machine holder and pilot hole dimensions for secure forming.
