WILKE turning blank DIN 4964, HSS‑EW9Co10, 4×4 mm, 80 mm

The WILKE turning blank is a hardened, finish‑ground square bar (Form B) made from high‑speed steel with 10% cobalt, intended for precision turning and small-series toolmaking

• Hardened and ground, 65–69 HRC for stable turning
• Square cross‑section 4 × 4 mm, tolerance h13
• Length 80 mm with ±2 mm length tolerance
• Material HSS‑EW9Co10 (Werkstoff 1.3207), 10% cobalt

Reliable material choice for demanding cutting tasks

The combination of HSS‑EW9Co10 and 10% cobalt delivers increased hot hardness and wear resistance compared with standard high‑speed steels, which helps to maintain edge integrity under elevated temperatures. With a specified hardness of 65–69 HRC, the bar provides a hard, wear‑resistant body that supports repeatable machining results. The material designation Werkstoff 1.3207 and the DIN reference underline a standardised composition, offering confidence for engineering and toolmaking environments where material consistency is essential.

Predictable geometry for fast set‑up and consistent parts

A square bar (Form B) with a 4 × 4 mm cross‑section and tolerance class h13 simplifies clamping and alignment in turning fixtures and toolholders. The 80 mm overall length and the specified ±2 mm length tolerance allow planners to account for stock removal and chucking clearance without guesswork. The body is finish ground, while the ends are straight and left unground; this configuration delivers a precise working surface along the length while allowing straightforward clamping at the ends.

Practical benefits in production and tooling applications

Conforming to DIN 4964, the bar is suitable as a solid blank for small turning operations, prototypes and precision tool components where material hardness and dimensional stability are required. The high cobalt content helps to extend tool life in intermittent cuts and under thermal load, reducing downtime for insert changes or regrinds. Specified tolerances and the standardised form support predictable machining cycles, helping to maintain process efficiency and reduce scrap rates in repeat production.

FAQ

What material is the turning blank made from?
The turning blank is manufactured from HSS‑EW9Co10 (Werkstoff 1.3207), a high‑speed steel alloy containing 10% cobalt for improved hot hardness.

What dimensions and tolerances apply to the bar?
The component has a 4 × 4 mm cross‑section (tolerance h13) and an overall length of 80 mm with a length tolerance of ±2 mm.

How hard is the material and why does that matter?
The specified hardness is 65–69 HRC; this level of hardness increases wear resistance and helps to keep cutting edges stable under thermal stress, benefiting tool life and process reliability.

Is the bar finish ground along its length?
Yes, the bar body is finish ground for dimensional stability, while the ends are straight and left unground.

Which standard does this turning blank follow and why is that useful?
Compliance with DIN 4964 and the designation Form B ensures standardised geometry for compatibility with fixtures and established tooling procedures.
