Turned blank DIN 4964 Form A Ø 12 mm — HSS‑EW9Co10 (1.3207) by Werner Wilke

The Turned blank DIN 4964 Form A Ø 12 mm HSS‑EW9Co10 is a hardened, finish‑ground round blank intended for precision turning and tooling applications in industrial workshops and toolrooms

• HSS‑EW9Co10 with 10% cobalt for high toughness
• Hardened to 65–69 HRC for wear resistance
• Diameter tolerance h8 for precision fit
• Length 200 mm, straight unground ends

Hardness and material composition that improve process stability

The blank is manufactured in HSS‑EW9Co10 (material number 1.3207) and contains approximately 10% cobalt, which increases hot hardness and toughness compared with standard high‑speed steels. The specified 65–69 HRC hardness ensures sustained wear resistance under heavy cutting and repeated cycling. For production environments this combination of material and hardness reduces tool‑related variation and extends service intervals, helping to keep turning processes predictable and economical.

Tight tolerances for repeatable assembly and clamping

A controlled diameter tolerance h8 and a length tolerance of ±2 mm deliver repeatability when mounting or gaging stock. With a nominal Ø 12 mm and a length of 200 mm, the rod suits collet, chuck or bar‑feed set‑ups that require accurate concentricity. These dimensional guarantees cut down on set‑up time and part rejection, supporting smoother production flow where interchangeability and predictable run‑out are essential.

Production finish that minimises preparation work

Supplied hardened, tempered and finish‑ground, the blank offers a machining‑ready surface for turning operations. The ends are supplied straight and unground, which permits secure clamping without altering the precision ground running surface. This manufacturing state reduces the need for additional grinding or heat treatment before use, so workshop throughput is improved and initial processing steps are minimised.

Practical suitability and handling considerations

The compact turning blank is suitable for a wide range of precision turning tasks in toolrooms and component manufacture where high wear resistance is required. The finish‑ground body aids concentricity and surface quality, while the unground ends accommodate standard clamping systems. For specific cutting data, workpiece materials or batch requirements, technical consultation is recommended to match the blank’s properties to the intended process.

FAQ

What material is this blank made from and why is it chosen?
The blank is manufactured from HSS‑EW9Co10 (1.3207); this grade with about 10% cobalt provides enhanced hot hardness and toughness compared with conventional high‑speed steels, making it suitable for demanding turning tasks.

What tolerances and dimensions can be expected for this product?
The turning blank has a nominal Ø 12 mm, length 200 mm, with diameter tolerance h8 and a length tolerance of ±2 mm, ensuring precise fit and repeatable clamping.

Is the blank ready for immediate machining straight from delivery?
Yes; the body is finish‑ground and hardened, while the ends are supplied straight and unground, which allows secure clamping and reduces preparatory work before turning operations.

Which standard does the blank conform to and what does that imply?
The blank complies with DIN 4964 Form A, indicating a round, standardised supply form for turning blanks that supports consistent dimensions and interchangeability in production environments.

Can this blank be used for high‑temperature cutting conditions?
The HSS‑EW9Co10 composition and the 65–69 HRC hardness improve performance at elevated temperatures compared with non‑cobalt HSS grades; for precise cutting parameters, consult technical data or Metav Werkzeuge’s specialists.
