Take advantage of a hardened, finish-ground square turning blank that combines high wear resistance and tight dimensional control for reliable batch production; order directly via Metav Werkzeuge or contact the consultants for application advice.

Wilke turning blank DIN 4964 Form B — HSS-EW9Co10, 5 x 5 mm, 80 mm

The Wilke turning blank is a square, pre-hardened bar stock for precision machining, suitable for small turning operations and finishing pulses.

• HSS-EW9Co10 with 10% cobalt for high hardness
• Hardened and finish-ground for consistent concentricity
• Square form B (5 x 5 mm) with h13 cross-section tolerance
• Length 80 mm with ±2 mm length tolerance

Faster setup and consistent machining results

The combination of finish-ground surfaces and a hardened core delivers repeatable seating and concentric running in chucks and fixtures, reducing setup time and scrap rates. The HSS-EW9Co10 alloy, containing 10% cobalt, ensures elevated red hardness and wear resistance compared with standard high-speed steels, which helps maintain cutting geometry during longer runs. With the 5 x 5 mm square cross section meet­ing h13 tolerance, the blank fits standard square collets and micro-fixtures without rework, supporting efficient, predictable production cycles.

Material engineering that extends tool life and stability

Supplied in 1.3207 grade and hardened to 65–69 HRC, the bar stock offers a stable substrate for fine turning, internal tooling and precision features where dimensional integrity matters. The high hardness reduces the frequency of regrinding or repositioning and makes the stock particularly suitable for applications that demand excellent edge retention and resistance to plastic deformation. Because the ends are straight but unground, the component allows secure clamping while preserving the ground length for critical machining, thereby balancing handling convenience with functional precision.

Clear specification for process planning and quality control

Conforming to DIN 4964, Form B, the component simplifies procurement and inspection: documented tolerances of ±2 mm length and h13 cross-section provide a verifiable basis for incoming inspection and automatic sorting. The square form reduces rotation risk in small chucks and supports consistent tool engagement, which is especially valuable in serial small-part manufacture. Where process engineers require traceability, the material designation and DIN reference allow direct comparison with supplier certifications and internal quality plans, aiding long-term cost-efficiency through fewer rejects and predictable tool cycles.

FAQ

What material is used for this turning blank and what are its benefits?
The turning blank is made from HSS-EW9Co10 (material 1.3207); the 10% cobalt content and hardened condition improve red hardness and wear resistance, extending service life in demanding turning operations.

Is the dimension tolerance suitable for collet chucking and micro-fixtures?
Yes. The 5 x 5 mm cross section is manufactured to h13 tolerance and the length is supplied as 80 mm with a ±2 mm tolerance, which supports reliable seating in square collets and miniature fixtures.

How does the finish-ground condition affect machining outcomes?
The finish-ground area enhances concentricity and predictable runout, reducing setup adjustments and improving repeatability across batches when using the Wilke turning blank.

Are the ends ready for immediate machining?
The ends are supplied straight but unground, permitting secure clamping while preserving the finish-ground length for critical machining operations.

Which standard and form identify this stock for procurement and inspection?
The stock conforms to DIN 4964, Form B (square), enabling clear specification in procurement orders and compatibility with documented inspection criteria (SKU 4118415040NW).
