TECWERK M12×1.25 HSS round die (Form B) — metric fine thread, tolerance 6g

The TECWERK M12×1.25 HSS round die (Form B) is a closed, pre‑slotted threading die for cutting metric ISO fine threads in steels up to approximately 800 N/mm².

• HSS cutting material for long life
• Metric fine thread M12×1.25, DIN 13 MF
• Closed, pre-slotted Form B design
• Tolerance 6g for accurate thread fit

Accurate fine threads for consistent assembly performance

The round die produces metric fine threads to DIN 13 MF, designed to ensure consistent mating with standard components. The combination of the fine-pitch profile M12×1.25 and the 6g tolerance provides a predictable thread fit, reducing rework and part rejection. This reliability translates into measurable savings in assembly time and quality control, particularly where repeated, identical threads are required across batches. Operators benefit from clear specification conformity, which supports traceability and process control in production environments.

High-speed steel construction for reduced downtime

Manufactured from HSS, the die offers enhanced durability and wear resistance compared with standard carbon-steel tooling. The robust cutting material extends tool life, maintaining sharp cutting edges through multiple passes and lowering replacement frequency. The closed, pre‑slotted Form B design balances full-profile cutting with effective chip clearance, helping to avoid clogging and minimising the need for frequent cleaning during runs. Fewer interruptions mean smoother workflows and better overall equipment effectiveness on the shop floor.

Versatile workshop use across common steels

Engineered for use in a broad range of workshops, the die handles machining of steels up to approximately 800 N/mm² tensile strength, making it suitable for many maintenance and production tasks. The compact height 10 mm format and standard metric sizing simplify integration into existing die stocks and holders. As a hand or machine-mounted threading die, it serves well in repair, prototyping and small-series production, delivering professional-grade results without specialised fixtures. The straightforward geometry eases setup and helps less experienced staff achieve reliable outcomes.

FAQ

What thread size and pitch does this die cut?
The die cuts a metric fine thread of M12×1.25, complying with the DIN 13 MF profile for consistent mating with standard components.

Which materials can be machined with this die?
The tool is specified for use on steels up to approximately 800 N/mm² tensile strength and is therefore suitable for a wide range of common workshop steels.

What does the Form B, closed pre‑slotted design mean for operation?
The Form B configuration provides a full‑profile, closed die for optimal thread geometry while the pre‑slotting improves chip evacuation and reduces the risk of clogging during continuous cutting.

How does the HSS cutting material benefit workshop processes?
HSS offers superior edge retention and wear resistance compared with standard steels, resulting in longer service life and fewer tool changes during repetitive threading tasks.

Is the threading accuracy suitable for production use?
Yes — with its 6g tolerance and DIN standard profile, the die is designed to deliver the dimensional accuracy and repeatability expected in small-series production and maintenance work.
