Turning blank DIN 4964, Form D – 12 x 6 mm HSS‑EW9Co10 (200 mm) by Werner Wilke

A high‑alloy tool blank intended for producing precision lathe tooling and toolholders, supplied in a hardened, tempered and finish‑ground condition for reliable edge preparation

• HSS‑EW9Co10 with 10% cobalt
• Hardened and finish‑ground, 65–69 HRC
• Rectangular Form D profile to DIN 4964
• Cross‑section 12 x 6 mm, tolerance h13
• Length 200 mm, length tolerance ±2 mm

Consistent performance from high‑alloy construction

The HSS‑EW9Co10 composition combines high‑speed steel with 10% cobalt, providing increased red hardness and improved thermal stability compared with standard high‑speed steels. This metallurgical mix translates into enhanced wear resistance and longer life for machined cutting edges when the blank is ground to final geometry. With a certified hardness of 65–69 HRC, the blank offers dimensional stability during subsequent tool manufacture and resharpening operations, reducing the frequency of rework and ensuring predictable tool behaviour under elevated cutting temperatures.

Precision profile and tolerances for reliable toolmaking

Conforming to DIN 4964 in Form D means the rectangular profile is suitable for standardised tool designs and fixtures. The 12 x 6 mm cross‑section with h13 tolerance provides a clear reference for clamping and holder compatibility, while the overall 200 mm length and ±2 mm length tolerance allow efficient batch processing and reproducible setups. Because the bar is supplied finish‑ground, the body benefits from accurate dimensions to minimise secondary machining; the straight, unground ends allow final positioning or custom end machining without compromising the finished centre section.

Workshop efficiency through ready‑to‑process blanks

Delivered as a single‑piece unit, the blank is hardened, tempered and finish‑ground to support rapid conversion into finished cutting or forming tools. The material designation 1.3207 identifies the substrate for heat‑treat and grinding specialists, enabling predictable material removal rates and surface quality when using standard tool‑grinding wheels and coolant practices. The combination of finish grinding and consistent alloy content reduces set‑up time, supports repeatable results and contributes to a smoother in‑house production flow for toolrooms and small series manufacturing.

FAQ

What material is the blank made from and what benefits does it bring?
The blank is manufactured from HSS‑EW9Co10, a high‑speed steel with 10% cobalt; this alloy improves red hardness and wear resistance, making the turning blank suitable for producing durable cutting tools.

Which dimensions and tolerances are supplied?
The bar has a 12 x 6 mm rectangular cross‑section with h13 tolerance and an overall length of 200 mm with a length tolerance of ±2 mm; these specifications correspond to the DIN 4964 Form D designation.

Is the bar ready for immediate tool production?
Yes. The Werner Wilke turning blank is hardened, tempered and finish‑ground so the body is dimensionally stable for grinding final geometries; the straight, unground ends allow custom end machining if required.

How is the product supplied and under which SKU?
The item is supplied individually (packaging unit 1) and is listed under SKU 4118420080NW for order and inventory handling.

For which applications is this blank intended?
Designed as a tool blank for toolrooms and small‑series production, the blank is tailored for manufacture of turning tools, holders and specialised cutting edges where alloy stability and high hardness are required.
