WILKE turning blank DIN 4964 Form B — HSS‑EW9Co10 square 8×8 mm, 200 mm

A WILKE turning blank engineered for precision turning and toolroom applications, produced to DIN 4964 Form B for consistent square stock.

• HSS‑EW9Co10 with 10% cobalt content
• Hardened to 65–69 HRC for extended life
• Square 8 x 8 mm cross-section, DIN 4964 Form B
• Length 200 mm with h13 cross-section tolerance

Outstanding material performance for demanding turning tasks

The high‑alloy composition of HSS‑EW9Co10 (material number 1.3207) provides enhanced hot hardness and abrasion resistance compared with standard high‑speed steels. With a 10% cobalt content, the steel maintains cutting integrity at elevated temperatures and under intermittent cutting loads, which translates into longer tool life and fewer interruptions in production. The specified hardness of 65–69 HRC indicates a thermally treated and finish‑ground condition that supports repeatable machining results and predictable wear behaviour.

Accurate geometry that speeds up setup and improves repeatability

Manufactured to DIN 4964 Form B, the square 8 x 8 mm cross‑section is finish‑ground to tight tolerances (h13) and supplied in a nominal 200 mm length. These dimensional controls reduce the need for repeated measurement and fitting at the lathe chuck or collet, therefore lowering setup time and scrap rates. Ends are supplied straight and unground, enabling flexible end preparation on arrival while the finish‑ground body guarantees consistent clamping and aligned rotation during turning operations.

Application benefits and practical considerations

This square turning stock is suited to precision turning, small‑batch components and toolroom tasks where material stability and wear resistance are essential. The combination of a hardened condition and high‑cobalt content makes the blank especially resilient when producing small parts or finishing operations that generate heat. Because the ends are unground, a quick facing operation will deliver optimal seating; the robust material condition reduces the frequency of replacement and supports predictable process planning.

Proven sourcing and quality assurance for the workshop

Sourcing via an experienced precision partner delivers added reliability: stock is filtered and distributed from a central European hub that emphasises consistent quality and supply continuity. Metav’s approach to supply chain reliability and product range supports efficient procurement for industry and craft, allowing workshops to consolidate suppliers while retaining access to high‑quality materials. This level of service helps maintain production throughput and a dependable inventory of turning blanks.

FAQ

What material is the bar made from and why is it chosen?
The turning blank is made from HSS‑EW9Co10 (1.3207); the 10% cobalt content improves hot hardness and wear resistance, which makes the material suitable for demanding turning operations.

Which dimensions and tolerances are supplied?
The WILKE turning blank is supplied in a 8 x 8 mm square section and 200 mm nominal length, with cross‑section tolerance h13 and a length tolerance of +/- 2 mm.

Are the ends prepared for immediate use in the chuck?
Ends are delivered straight and unground, while the body is finish‑ground; a facing operation is recommended for optimal seating before chucking.

Is the bar coated or treated beyond hardening?
No coating is specified; the product is provided hardened, tempered and finish‑ground as indicated in the technical description.
