Wilke turning blank DIN 4964 Form A — HSS‑EW9Co10, Ø 8 mm, L 160 mm

The Wilke turning blank DIN 4964 Form A is a hardened, tempered and finish‑ground HSS bar designed for precision turning and toolmaking in industrial workshops

• HSS‑EW9Co10 with 10% cobalt for toughness
• Hardened to 65–69 HRC, ground finish
• Diameter Ø 8 mm with h8 tolerance
• Length 160 mm, length tolerance ±2 mm

Consistent material and hardness for repeatable machining results

The core material, HSS‑EW9Co10, combines high‑speed steel matrix with 10% cobalt, producing increased red‑hardness and wear resistance compared with standard HSS grades. This means longer life under elevated cutting temperatures and more predictable tool performance when producing small batches or series parts. The specified 65–69 HRC hardness range indicates a fully hardened and tempered condition that resists plastic deformation during finishing operations, while the finish‑ground surface improves seating and concentricity in collets and chucks.

Tight tolerances and dimensional stability that simplify setup

A defined diameter tolerance h8 together with a length tolerance of ±2 mm reduces the need for additional pre‑grinding or reworking prior to tool fabrication. The Ø 8 mm diameter and 160 mm length are standard formats for many precision turning and cutting tool applications, enabling quick clamping and repeatable centring. Because the ends are delivered straight and unground, the component accommodates custom end preparations while maintaining overall dimensional integrity, which shortens machine setup time and reduces scrap rates.

Clear benefits for toolmakers and precision workshops

Delivered as a solid, straight bar in accordance with DIN 4964 Form A, the component supports a range of downstream processes such as toolholder turning, jig finishing and small batch production. The combination of cobalt‑enriched HSS and a finish‑ground condition enhances surface finish on final parts and lowers the frequency of tool replacement. For workshops seeking reliable feed rates and consistent edge retention, this material specification offers an economical balance between performance and longevity.

Quality features that support process reliability

Manufacture to the given DIN standard and the stated material number (1.3207) provides traceability and a verifiable material basis for quality control documentation. The hardened and tempered treatment, along with finish grinding, results in minimal internal stresses and improved straightness — attributes that matter when producing precision tools or accurate turned components. Clear labelling and SKU tracking facilitate inventory management and repeat ordering for production continuity.
