Turning blank DIN 4964 Form A — Ø14 mm, HSS‑EW9Co10, hardened 65–69 HRC (WILKE)

The Turning blank DIN 4964 Form A is a round, hardened and ground bar in HSS‑EW9Co10, designed for precision turning and small‑batch component manufacture in tool rooms and specialised workshops.

• HSS‑EW9Co10 with 10% cobalt
• Hardened and tempered, ground finish
• Diameter Ø14 mm, tolerance h8
• Length 200 mm, length tolerance ±2 mm

Consistent cutting performance from high‑speed steel with cobalt

The bar is made of HSS‑EW9Co10, a high‑speed steel alloy that contains 10% cobalt, which increases hot hardness and wear resistance compared with conventional grades. With a hardness of 65–69 HRC, the material provides a stable cutting edge under intermittent high loads and improves tool life where repeated regrinding or finishing is required. This results in fewer interruptions for rework and a predictable lifetime profile for blanks used in precision turning and toolmaking.

Tight dimensions to reduce set‑up and improve concentricity

A nominal diameter of Ø14 mm combined with h8 diameter tolerance and a length of 200 mm (length tolerance ±2 mm) gives a consistent datum for chucking and collet gripping. The straight, unground ends facilitate secure seating while the ground outer surface ensures good concentricity for finishing operations. These dimensional assurances translate into shorter machine set‑up times and more predictable runout behaviour when producing cylindrical components or shafts.

Ready for precision machining and standardised workflows

Conforming to DIN 4964 Form A, the round blank arrives hardened and ground, making it suitable for immediate integration into established production flows without additional pre‑treatment. The material number 1.3207 identifies the grade for documentation and process planning, while the nominal hardness and cobalt content support higher cutting speeds and consistent finishing. The blank is aimed at precision workshops, toolmakers and manufacturers of small turned parts who require standardised, high‑quality starting stock from a reliable supplier

FAQ

What alloy is used for this turning blank and why is it chosen?
The turning blank is produced from HSS‑EW9Co10 (material number 1.3207); the 10% cobalt content improves hot hardness and wear resistance, making the blank suitable for high‑precision and high‑stress turning applications.

Is the blank supplied ready for machining or is additional heat treatment required?
The Turning blank DIN 4964 Form A is supplied hardened and ground, ready for immediate machining operations without further heat treatment.

Which dimensional tolerances are guaranteed for the round bar?
The bar is specified as Ø14 mm with h8 diameter tolerance and a length of 200 mm with a length tolerance of ±2 mm, providing consistent datum points for clamping and finishing.

Can this blank be used for toolmaking and small‑series production?
Yes; the material properties, 65–69 HRC hardness and finish grinding make the blank well suited to toolmaking, prototype components and small‑series turned parts.
