M4x0.7mm Threading Die Form B Left-Hand HSS 6g Tolerance, 5mm Height - TECWERK

Combining HSS durability, precise M4×0.7 metric threading and a left‑hand cutting orientation, this Form B closed pre‑slit die delivers reliable thread production in steels up to approx. 800 N/mm²; order the threading die directly via Metav Werkzeuge or consult our specialists if application advice is required.

TECWERK Threading Die Form B M4×0.7 HSS (left‑hand, 6g)

A left‑hand TECWERK threading die Form B M4×0.7 for cutting metric ISO threads in steel components and maintenance tasks

• HSS material for durable cutting life
• Metric ISO M4 × 0.7 thread form 6g
• Left‑hand cutting for reverse-thread applications
• Closed, pre‑slit Form B for clean thread finish

Consistent metric threads with industrial tolerance control

The tool is designed to cut M4×0.7 metric ISO threads to DIN 13 with a 6g tolerance field, providing a predictable external thread fit for assembly and repair operations. Manufactured from HSS, the die sustains its edge geometry during repeated use, which reduces the need for early replacement and supports steady cycle times. For engineers and workshop managers, the measurable specification of 6g and compliance with DIN standards translates into fewer rejects and simpler quality control.

Closed Form B geometry for clean results and stable handling

The Form B closed design, supplied in a closed, pre‑slit construction, concentrates the cutting action and helps produce a consistent flank form with lower burr formation. With a nominal height of 5 mm, the die provides adequate contact surface for stable engagement in a holder while limiting material buildup. This geometry simplifies rework: parts leave the threading operation ready for assembly or finishing, which reduces downstream corrective work and improves overall process reliability.

Left‑hand cutting and material capability for specialised tasks

Specifically manufactured as a left‑hand cutting tool, this die suits reverse-thread applications, maintenance work on assemblies with counter-rotating fastenings, and repair scenarios where reversing thread direction is required. The cutting material and construction enable machining in steels up to approx. 800 N/mm² tensile strength, balancing toughness with wear resistance. For production technicians and toolroom staff, the combination of HSS and standardised thread form increases uptime and ensures repeatable results across batches.

FAQ

What thread form and tolerance does the die produce?
The die produces metric ISO threads in M4×0.7 to DIN 13 with a 6g tolerance field, suitable for standard external thread fits.

Is this tool suitable for hardened steels?
The TECWERK threading die is intended for use in steels up to approx. 800 N/mm² tensile strength; for higher hardness levels specialised tools should be considered.

Why choose a closed, pre‑slit Form B die?
A closed, pre‑slit Form B die gives a cleaner thread finish and more stable cutting action, reducing burrs and simplifying subsequent assembly operations.

Can this die produce left‑hand threads reliably?
Yes, the die is manufactured as a left‑hand cutting tool specifically for reverse-thread applications and maintenance tasks requiring counter‑direction threads.

Which material is the die made from and what does that mean for durability?
Constructed from HSS, the die combines toughness and wear resistance for prolonged cutting life and consistent thread quality.
