M18x2.5mm Threading Die Form B HSS-Co For Difficult-To-Machine Alloys 18mm Height - TECWERK

Formulated for robust, repeatable threading in demanding environments, this die combines HSS‑E cutting material with a 6g tolerance and a closed, pre‑slit Form B design to produce accurate metric threads in hard‑to‑machine alloys; Order the TECWERK M18×2.5 die directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK round die Form B M18×2.5 HSS‑E 6g

TECWERK round die Form B M18×2.5 HSS‑E 6g is a metric ISO threading die designed for cutting external threads in high‑strength, corrosion‑resistant and special alloy steels.

• HSS‑E cutting material for high hot hardness
• Metric ISO M18×2.5 thread, tolerance 6g
• Closed, pre‑slit Form B for better chip control
• Suitable for stainless and high‑strength alloys up to 1200 N/mm²

Reliable cutting performance and extended tool life

The use of HSS‑E (cobalt‑alloyed high‑speed steel) gives this die superior wear resistance and elevated hot hardness compared with standard steels, which translates into longer service life under heavy use. For operations that demand repeatable thread quality, the combination of the cobalt‑enriched cutting material and the die’s geometry reduces the frequency of tool changes and rework. This performance advantage is particularly valuable in small series production and maintenance workshops where downtime and consumable turnover are critical cost factors.

Engineered for hard‑to‑machine and stainless materials

Designed specifically for use with stainless, heat‑ and acid‑resistant steels, special alloys and steels up to 1200 N/mm², the die maintains cutting stability where conventional tooling can fail. The geometry and material selection control temperature at the cutting edge and improve chip formation, which prevents galling and preserves thread profile integrity. For processors working with demanding materials, this behaviour means cleaner thread flanks and consistent tolerance adherence, supporting downstream assembly and sealing functions without additional finishing passes.

Standards, tolerance and practical design for precise threads

Conforming to DIN EN 22568 and intended for metric ISO thread DIN 13, the tool delivers threads to 6g tolerance for reliable external fits. The Form B configuration in a closed, pre‑slit design balances rigidity and chip clearance: the closed outer ring ensures concentricity and guidance during cutting, while the pre‑slit sections permit controlled expansion and chip evacuation. With a working height of 18 mm, the die is compact yet robust, suitable for bench use and holder systems where stability and repeatability are required. This combination of standards and form provides clear orientation for quality assurance and simplifies selection in technical procurement.

FAQ

What materials is this die suitable for?
The TECWERK round die M18×2.5 HSS‑E 6g is suitable for stainless steels, heat‑ and acid‑resistant steels, special alloys and carbon steels up to around 1200 N/mm² tensile strength.

Which thread standard and tolerance does it meet?
Threads produced by this die conform to metric ISO thread DIN 13 and the die is manufactured to DIN EN 22568 with a tolerance class of 6g.

What advantage does HSS‑E offer for threading?
HSS‑E in the TECWERK die increases hot hardness and wear resistance during continuous cutting, improving lifespan and maintaining thread geometry in demanding applications.

How does the closed, pre‑slit Form B affect performance?
The closed outer form gives guidance and concentricity, while the pre‑slit design allows controlled expansion and better chip evacuation, which reduces the risk of jamming and improves surface quality.

Is this item available for single purchase or only in sets?
The product is supplied in a packaging unit of 1 under SKU 2000867849NW for single‑item procurement.
