Wilke turning blank DIN 4964 Form A — Ø 12 mm, HSS‑EW9Co10, L 100 mm

A Wilke turning blank designed as round bar stock for precision turning and small-series toolmaking according to DIN 4964 Form A.

• HSS‑EW9Co10 with 10% cobalt
• Hardness 65–69 HRC for wear resistance
• DIN 4964 Form A round stock
• Diameter tolerance h8, length ±2 mm

Durable alloy for longer tool life and stable machining

The use of HSS‑EW9Co10 (workpiece number 1.3207) delivers a balanced combination of toughness and hot‑hardness that supports consistent cutting performance under elevated temperatures. With 10% cobalt alloying, the blank maintains cutting edge strength where pure high‑speed steels would soften, so fewer premature re‑grinds are required. This translates into less downtime and a more predictable component quality for production environments that prioritise process stability.

Precision dimensions to reduce finishing work

Manufactured to DIN 4964 Form A as a round bar with an Ø 12 mm nominal diameter and length 100 mm, the stock is supplied finish ground with a diameter tolerance h8 and a length tolerance of ±2 mm. The tight diameter specification reduces the need for extensive set‑up or corrective turning before machining complex geometries, helping maintain throughput. For purchasers seeking measurable assurance, the specified tolerances provide a verifiable basis for integration into existing manufacturing chains.

Heat treatment and surface condition explained for non‑specialists

The blank is hardened, tempered and finish ground, producing a surface and metallurgical state that is ready for subsequent turning or tool fabrication without additional heat treatment. Hardness at 65–69 HRC indicates a very hard material typically used where edge retention and abrasion resistance are priorities; in practical terms, this means the blank resists wear during high‑speed cuts and offers longer service life in cutting‑edge applications. Ends are supplied straight and unground, which is standard for blanks intended for clamping or further machining to final dimensions.

Integration into workshop workflows and handling recommendations

Supplied as a compact turning blank, the component is suited to small‑batch toolmaking, sample production and repair work where consistent material properties are essential. The combination of HSS‑EW9Co10 metallurgy and finish grinding simplifies downstream operations: less variation in machining forces, predictable tool wear, and stable part tolerances. For integration into automated workflows, the consistent h8 diameter tolerance supports secure clamping and repeatable indexing on chucks or collets.

FAQ

What is the material composition of the blank?
The blank is made from HSS‑EW9Co10 (material number 1.3207) containing 10% cobalt, providing enhanced hot‑hardness.

What diameters and lengths are supplied?
This turning stock is supplied as Ø 12 mm with a length of 100 mm and a diameter tolerance of h8.

How hard is the material and what does that imply for machining?
Hardness is 65–69 HRC; this high hardness level gives excellent wear resistance but requires appropriate cutting tools and parameters when machining the Wilke turning blank.

Are the ends of the blank ready for immediate clamping?
Ends are straight and unground, which is typical for blanks intended for clamping or further machining to final dimensions.

Which standard does the blank conform to?
The component conforms to DIN 4964 Form A, indicating round bar stock prepared for turning operations.
