TECWERK Threading Die M4 x 0.7 mm, Form B (HSS‑E, 6g)

A TECWERK Threading Die M4 x 0.7 mm designed for cutting precise metric external threads in stainless and high‑strength alloys

• HSS‑E high‑cobalt cutting material
• Metric ISO threads to DIN 13, tolerance 6g
• Suitable for stainless and acid‑resistant steels
• Closed, slotted Form B; 5 mm height

Reliable threading for demanding materials

The die is manufactured from HSS‑E (high‑cobalt high‑speed steel), a cutting material chosen for its improved heat resistance and wear behaviour when machining difficult materials. That composition supports consistent cutting performance in high‑strength alloys and steels with tensile strengths up to 1200 N/mm², reducing tool wear and minimising rework. The robust material selection translates into longer intervals between tool changes and steadier process output in small‑batch and repair environments.

Consistency with industrial tolerances and standards

Engineered to the metric ISO specification and DIN 13, the tool produces external threads within tolerance 6g, ensuring reliable fit and interchangeability in assembly operations. The defined tolerance class helps avoid thread play or excessive tightness, which in turn reduces scrap rates and the need for trial‑and‑error adjustments. For mechanical assemblies where repeatability matters, conformity to these standards delivers measurable process stability and predictable mating behaviour.

Practical form and chip control for workshop use

The closed, slotted Form B offers a compact geometry with integrated slots for chip evacuation, while the modest 5 mm height provides a stable cutting edge in a small envelope. This combination suits work with fixed die holders or hand‑held stocks and aids in maintaining concentricity during the cut. Correct use of cutting fluid and steady feed rates improves surface finish and extends tool life, making the tool a pragmatic choice for maintenance tasks and on‑bench thread repairs.

Durable design for efficient production

By combining a corrosion‑ and heat‑resistant substrate with a compact, workshop‑oriented shape, the die supports efficient throughput and predictable maintenance cycles. The solid construction reduces downtime associated with frequent replacements and contributes to lower total operating costs over time. For operations requiring dependable external threads without complex setup, this die presents a practical balance of precision, longevity and ease of handling.

FAQ

Which materials can be machined with this threading die?
The TECWERK Threading Die M4 x 0.7 mm (HSS‑E) is suitable for stainless, heat‑ and acid‑resistant steels, special alloys and steels up to approximately 1200 N/mm² tensile strength.

What does the tolerance 6g indicate for external threads?
Tolerance 6g denotes the standard external thread tolerance for metric threads under DIN/ISO, providing a reliable fit for general industrial applications and ensuring interchangeability with corresponding internal threads.

Does the die conform to recognised standards?
Yes, the tool is manufactured to metric ISO specifications and references DIN 13, which governs dimensional and tolerance requirements for metric screw threads.

Can this die be used with a standard die stock or holder?
The closed, slotted Form B is designed for use with conventional die holders or stocks; correct clamping and the use of cutting fluid are recommended to ensure thread quality and to extend tool life.

How should the die be maintained after use?
Remove chips, apply a light protective oil and store the die dry. Occasional inspection for wear and keeping cutting edges free from built‑up material will preserve performance.
