WILKE turning blank DIN 4964 Form A — 4 mm, HSS‑EW9Co10

The WILKE turning blank DIN 4964 Form A is a round, hardened and ground bar designed for precision turning applications in toolmaking and small-series production.

• HSS‑EW9Co10 with 10% cobalt
• Hardness 65–69 HRC
• Diameter tolerance h8
• Ground finish and straight ends

Consistent cutting behaviour through high‑performance material

The use of HSS‑EW9Co10 (Werkstoff 1.3207) delivers improved red hardness and wear resistance compared with conventional high‑speed steels, which translates into more consistent cutting behaviour under thermal load. With a cobalt content of 10%, the material maintains hardness at elevated temperatures, reducing flank wear and extending blank life. This translates into fewer re‑grinds and steadier machine cycles for precision turning operations.

Predictable dimensional accuracy for repeatable parts

Manufactured to DIN 4964 Form A, the round blanks are ground and supplied with straight, unground ends to simplify clamping and preparation. The diameter 4 mm with h8 tolerance and length 80 mm supports tight concentricity and repeatable set‑ups on lathes and CNC turning centres. The 65–69 HRC heat treatment ensures dimensional stability in short runs and helps maintain concentricity during machining, reducing scrap and increasing first‑pass yields.

Practical benefits for workshop efficiency

Using a pre‑finished turning blank minimises preparation time: the ground surface reduces balancing and centring effort, while uniform hardness offers consistent tool life across batches. For small workshops and specialist toolrooms, the blanks provide a reliable starting point for prototyping, small batch production or specialised tooling components. Combined with Metav’s supply chain and quality filtering from Emmerich, this provides a pragmatic route to integrating precision blanks into existing processes with minimal disruption.
