Wilke Turning Blank DIN 4964 Form A (HSS-EW9Co10, Ø 18 mm, L 200 mm)

Wilke Turning Blank DIN 4964 Form A is a hardened, precision-ground round bar designed for machining centres and toolrooms where repeatable concentricity and wear resistance are essential

• HSS-EW9Co10 with 10% cobalt
• Hardened to 65–69 HRC
• Precision-ground round bar, DIN 4964 Form A
• Diameter tolerance h8, length tolerance ±2 mm

Outstanding material performance for hot cutting and wear resistance

Manufactured from HSS-EW9Co10, the blank combines high-speed steel chemistry with 10% cobalt to boost hot hardness and abrasion resistance during indexed or continuous cutting. The material's thermal stability reduces flank wear at elevated temperatures, which translates into longer tool life and fewer regrinds. The bar is hardened to 65–69 HRC, ensuring structural stability for demanding turning operations while maintaining machinability for subsequent finishing steps.

Predictable dimensions that reduce setup time and rework

With a nominal Ø 18 mm and L 200 mm, the component is finished to DIN 4964 Form A with diameter tolerance h8 and length tolerance ±2 mm, supporting repeatable clamping and consistent run-out in chucks and collets. The blank is precision-ground so concentricity is reliable from piece to piece; ends are straight and supplied unground for easy datum setting. These measured characteristics lower setup overhead and reduce scrap, making the blank suitable for small-batch production and prototype runs.

Practical workshop benefits and application guidance

Identified by material number 1.3207, the round bar is tempered, finished and supplied ready for immediate turning or further toolmaking processes. The combination of hardness and cobalt content makes the blank suitable for components that require dimensional stability and wear resistance, especially in tool and die, valve and small-engine parts production. The straight, unground ends simplify fixturing, while the precision-ground shaft minimises the need for pre-machining, improving throughput in busy workshops.

FAQ

What material is the blank made from and what are its benefits?
The blank is manufactured from HSS-EW9Co10 (material number 1.3207), offering improved hot hardness and wear resistance thanks to its 10% cobalt content; this makes the Wilke turning blank suitable for demanding machining tasks.

What are the exact dimensions and tolerances of the bar?
The turning blank has a nominal Ø 18 mm and L 200 mm with diameter tolerance h8 and length tolerance ±2 mm, supplied finish-ground for predictable clamping and concentricity.

Is the blank ready for immediate machining?
Yes, the bar is delivered hardened, tempered and finish-ground, so the Wilke turning blank can be used directly for turning or further toolmaking without preliminary heat treatment.

Which applications are appropriate for this turning blank?
The blank is intended for precision turning and small-series component manufacture where high wear resistance and dimensional stability are required, for example in toolmaking and mechanical parts production.

How does the hardness affect processing and tool choice?
With a hardness of 65–69 HRC, the blank retains form stability under load; carbide tooling and appropriate cutting data are recommended when machining this grade to achieve optimal surface quality and tool life.
