Turning blank DIN 4964 — Form B, square 18 x 18 mm (HSS‑EW9Co10) by Werner Wilke

A turning blank for precision bar work and small series turning, supplied as a square blank in Form B to DIN 4964 for immediate use in machining centres and toolmaking.

HSS‑EW9Co10 with 10% cobalt for increased wear resistance
Hardened 65–69 HRC, finish‑ground for repeatable accuracy
Square profile 18 x 18 mm with tolerance h13
Length 200 mm with length tolerance ±2 mm

Precision and predictable machining for repeatable components

The blank is manufactured from HSS‑EW9Co10, a high‑speed steel alloy enriched with 10% cobalt, optimised for high thermal stability and abrasion resistance. The 65–69 HRC hardening and subsequent finish‑ground condition ensure a uniform surface and consistent concentricity, reducing setup variation and trial cuts. For production environments where repeatability matters, this material and heat treatment lower tool change frequency and maintain dimensional integrity across batches.

Material choice that extends service intervals and performance

Selecting a turning blank in HSS‑EW9Co10 provides higher red hardness compared with conventional HSS grades; the added cobalt stabilises carbide phases at elevated temperatures, which translates to slower flank wear and better edge retention. For applications involving interrupted cuts or harder steels, the 10% cobalt content supports longer runtimes and fewer regrinds, therefore improving overall throughput and reducing indirect machining costs.

Dimensional reliability to integrate into tight workflows

The square cross‑section of 18 x 18 mm held to tolerance h13, together with a length of 200 mm and a length tolerance of ±2 mm, enables predictable clamping and minimal repositioning. Finished ends are supplied straight and unground, allowing flexible fixturing or a final customer‑side facing operation. Conformance to DIN 4964, Form B simplifies specification management and ensures compatibility with standard fixtures and chucks used in small‑part turning.

Ready for production and easy handling on the shopfloor

Supplied as a single, factory‑prepared blank, the component is hardened, tempered and finish‑ground, making it suitable for immediate integration into toolmaking, prototyping or short production runs. The combination of material specification and geometric tolerances reduces preparatory steps and enables engineers to focus on cutting parameters rather than corrective setup—helping maintain steady cycle times and predictable surface finish results.

FAQ

What material is the blank made from and why is it suitable for turning?
The turning blank is made from HSS‑EW9Co10 (material number 1.3207); the alloy’s 10% cobalt content increases red hardness and wear resistance, making the blank well suited for precision turning and interrupted cuts.

What are the exact dimensions and tolerances of the blank?
The blank is supplied as a square 18 x 18 mm profile, 200 mm long, with cross‑section tolerance h13 and length tolerance ±2 mm (SKU 4118415185NW).

Is the blank ready to machine immediately on delivery?
Yes. The Wilke blank is hardened, tempered and finish‑ground, with straight, unground ends, allowing immediate use in production after appropriate fixturing.

How does the heat treatment benefit production runs?
The 65–69 HRC hardness provides consistent edge support and dimensional stability during machining, which helps reduce rework and prolongs the life of cutting tools when working with this blank.
