Turning blank DIN 4964 Form D — rectangular 16 x 4 mm, HSS‑EW9Co10 (WILKE)

The Turning blank DIN 4964 Form D is a hardened and finish‑ground rectangular machining blank intended for precision toolmaking and for the manufacture of cutting inserts and small turning tools in workshop environments.

• HSS-EW9Co10 with 10% cobalt
• Hardened to 65–69 HRC
• Rectangular 16 x 4 mm cross-section
• Length 160 mm, length tolerance ±2 mm

Consistent cutting performance from a cobalt‑enriched high‑speed steel

Made from HSS‑EW9Co10, this machining blank combines the heat resistance and wear properties typical of high‑speed steel with a 10% cobalt reinforcement, improving red hardness and edge retention during intermittent thermal loads. The specified hardness 65–69 HRC indicates a material condition suitable for holding a keen cutting geometry after profile grinding, which benefits precision toolmakers aiming for long life between re‑grinds. Conformity with DIN 4964 and the finished surface treatment reduce preparation time prior to final machining.

Practical format for efficient tool fabrication and small‑batch production

The rectangular 16 x 4 mm cross‑section and 160 mm length provide a standardised blank that fits typical tool holders and grinding fixtures, facilitating repeatable set‑ups. The blank format is particularly useful where form tools or single‑point cutters are produced in‑house, allowing controlled material removal and simplified clamping. The combination of a regular cross‑section and finish grinding supports predictable material behaviour during shaping and heat treatment steps.

Machining readiness and dimensional reliability for workshop workflows

Delivered hardened, tempered and finish‑ground, with ends straight and unground, the blank is ready for secondary operations while leaving mounting and face machining options open. Cross‑sectional tolerance h13 and a length tolerance of ±2 mm define expected dimensional variation and support reliable fixturing. The unground ends permit custom end preparation, and the indicated material number 1.3207 aids traceability and material verification during purchasing and inventory control.

FAQ

What is this blank best used for?
This turning blank is designed as a raw form for precision toolmaking; the HSS‑EW9Co10 material and rectangular profile make it suitable for producing small cutting tools and inserts.

Is the material already hardened and ready for grinding?
Yes, the blank is delivered hardened, tempered and finish‑ground, which reduces preparation work before profile grinding.

What tolerances can be expected for dimensioning?
Cross‑sectional tolerance is h13 and length tolerance is ±2 mm according to the product specification.

Are the end faces prepared for immediate mounting?
The ends are supplied straight and unground, allowing custom end finishing or fixturing depending on the intended application.

Can the material be re‑sharpened and re‑ground after use?
The 65–69 HRC condition and HSS‑EW9Co10 composition support multiple regrinds; final tool life will depend on application and grinding practice.
