TECWERK M8×1.25 Form B HSS Threading Die – 6g, DIN 13

A TECWERK M8×1.25 Form B HSS threading die engineered for cutting metric ISO threads in steels up to approximately 800 N/mm², ideal for precise repair and series production tasks

• HSS cutting material for durability
• Metric ISO threads to DIN 13, tolerance 6g
• Closed, pre-slit Form B design
• Suitable for steels up to 800 N/mm²

Consistent metric threads for production reliability

The die is manufactured to DIN EN 22568, providing conformity with established workshop standards. The M8×1.25 specification and tolerance 6g ensure that threads meet the dimensional requirements of ISO metric fasteners, reducing mismatches and rework. Using high-quality standards as a basis enables predictable interchangeability in assemblies and supports quality control processes in both small-batch and larger production environments. This technical consistency translates directly into fewer rejects and a steady production flow.

Durable HSS body for extended service life

Built from high-speed steel (HSS), the tool offers a robust cutting edge and resistance to wear under regular use. The Form B geometry, closed and pre-slit, balances cutting stability with controlled chip evacuation, which helps preserve cutting edges and maintain thread geometry over longer runs. For workshops processing medium-strength steels — up to about 800 N/mm² tensile strength — the material selection and construction deliver a favourable life-cycle performance, lowering downtime and tool change frequency.

Practical design for straightforward integration

With a compact 9 mm height and conventional metric profile, the component integrates into standard die holders and workshop procedures without requiring special adapters. The closed design supports reliable engagement with blanks and stock, while the pre-slit feature simplifies initial alignment and reduces the tendency to grab or miscut. These design choices mean that thread cutting can be carried out efficiently with hand-held die stocks or compatible fixtures, maintaining thread quality across multiple operations.

Procurement and operational advantages for buyers

Specifying a tooling solution that complies with recognised standards and employs HSS construction reduces uncertainty in supply chains and maintenance planning. The die’s conformity to DIN 13 metric thread forms supports spare-part interchangeability and simplifies procurement documentation. For decision-makers, the combination of defined tolerances, standard compliance and durable materials represents a clear cost-benefit: fewer interruptions, consistent part quality and straightforward replacement when required.
