WILKE turning blank DIN 4964 Form B — square 12 x 12 mm HSS‑EW9Co10, 100 mm

The WILKE turning blank is a hardened, square high‑speed steel blank designed for precision turning, toolmaking and small‑batch production in accordance with DIN 4964 Form B.

• HSS‑EW9Co10 with 10% cobalt
• Hardened to 65–69 HRC
• Square section 12 x 12 mm h13
• Length 100 mm, ends unground

Durable alloy for sustained cutting performance

The blank is manufactured from HSS‑EW9Co10, a high‑speed steel alloy containing 10% cobalt, which increases hot hardness and resistance to thermal softening during interrupted cuts. This composition, combined with a final hardness of 65–69 HRC, translates into improved wear resistance and a longer service life under cyclic loads. For users machining tougher steels or performing high feed operations, the material choice reduces flank wear and maintains cutting geometry for more consistent part tolerances.

Predictable fit and machining owing to defined tolerances

Supplied with a 12 x 12 mm square cross section to tolerance h13 and a nominal length of 100 mm with a length tolerance of ±2 mm, the blank offers a predictable starting condition for set‑up and further processing. The ends are supplied straight and unground, which facilitates centring or clamping before final facing; the body, being hardened, tempered and finish ground, provides stable reference faces that reduce rework. As a result, cycle‑to‑cycle variation is lower and batch reproducibility is improved in jigged or fixture‑based operations.

Versatile use and practical handling for workshop and production

Conforming to DIN 4964 Form B, the square turning blank is suitable for toolmakers, maintenance workshops and small production lines that require reliable blanks for internal tool fabrication or custom cutters. The combination of finish grinding and the stated hardness means the blank can be machined with predictable behaviour or used as a robust starting element for specialised tooling. Where high temperature resistance is required during heavy cutting, the cobalt alloy composition reduces the need for frequent tool changes, supporting uninterrupted production runs and lower tooling overhead.

FAQ

What is the primary benefit of HSS‑EW9Co10 for turning applications?
The HSS‑EW9Co10 alloy in this turning blank provides enhanced hot hardness and wear resistance; the material composition helps the blank maintain cutting edge geometry during heavy or intermittent cuts.

Can this square blank be used directly in fixture work without pre‑grinding the ends?
The ends are supplied straight and unground, allowing for clamping or facing as required; the body is finish ground to provide stable reference surfaces for fixture set‑up.

What does the tolerance h13 on the 12 x 12 mm section mean for fit‑up?
Tolerance h13 indicates a defined manufacturing tolerance for the cross section that supports reproducible clamping and predictable machining allowance for further finishing operations.

Is the hardness range suitable for toolmaking and small cutter production?
Yes, the specified 65–69 HRC provides the hardness expected for tool blanks and supports longevity under typical toolmaking operations.
