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.

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.

Take advantage of the combination of HSS cutting material, metric ISO fine thread conformity and a closed, pre-slotted Form B design for reliable, repeatable thread production; order the die directly via Metav Werkzeuge or ask the consultants for tailored advice. TECWERK thread cutting die MF16x1.5mm — HSS Form B, 6g tolerance The TECWERK MF16x1.5mm thread cutting die is a closed, pre-slotted Form B die for producing metric ISO fine threads to DIN 13 in steels up to approximately 800 N/mm². HSS material for durable cutting performance Metric fine thread MF16x1.5 to DIN 13 Tolerance field 6g for consistent accuracy Closed, pre-slotted Form B for stable chip control Consistent, standard-compliant thread accuracy for industrial use Designed in accordance with DIN 13 and manufactured to DIN EN 22568, this cutting tool gives clear, measurable results for metric fine threads. The combination of HSS cutting material and a 6g tolerance field ensures high accuracy and wear resistance when producing internal threads. For fabrication and repair tasks where repeatability matters, the standard conformity provides a verifiable baseline: thread geometry and tolerance are defined, measurable and comparable across batches and suppliers. Robust geometry and chip control that reduce rework The closed, pre-slotted Form B shape provides structural stability while allowing controlled chip evacuation during threading operations. A height of 14 mm delivers the necessary engagement length for forming complete, reliable threads in one pass on suitable stock. The sturdy build handles steels with tensile strengths of up to approx. 800 N/mm², reducing the frequency of tool changes and minimising the risk of thread defects that would otherwise lead to rework or scrap. Workflow advantages: reliability, speed and predictable results Using a purpose-made metric fine-thread die cuts cycle time and improves process reliability compared with improvised methods. The die’s geometry and HSS composition support higher tool life under normal threading conditions, meaning fewer interruptions for tool replacement. Clear technical standards and the die’s repeatable performance contribute to predictable production planning and quality inspection procedures, helping machining shops and maintenance departments keep throughput steady.
