Turning blank DIN 4964 Form B — 10 x 10 mm HSS‑EW9Co10, 200 mm — Wilke

A turning blank DIN 4964 Form B designed for precision turning and toolmaking applications, providing a hardened and ground square bar for reliable clamping and machining.

• Hardened to 65–69 HRC for extended life
• HSS with 10% cobalt for high heat resistance
• Precise 10 x 10 mm square cross section h13
• Length 200 mm; straight ends, ground finish

Consistent performance through material choice and hardness

The bar stock is manufactured from HSS‑EW9Co10 (material 1.3207), a high‑speed steel alloy with 10% cobalt that improves red‑hardness and wear resistance under elevated cutting temperatures. Combined with a 65–69 HRC hardness rating, this composition reduces flank wear and prolongs service intervals, which is particularly beneficial for serial turning operations where tool life and reproducible results are essential. The choice of material and heat treatment therefore supports cost‑effective production by reducing downtime and tool changes.

Precision dimensions and tolerances for reliable set‑up

With a 10 x 10 mm square cross section produced to h13 tolerance and a nominal length of 200 mm, the item provides a reproducible datum for chucks and collets. The length tolerance of +/- 2 mm and straight, ground ends simplify fixturing and ensure accurate axial positioning without the need for additional machining. These dimensional assurances translate into shorter set‑up times and fewer rejects when integrating the blank into existing workflows or bespoke fixtures.

Machining suitability and practical benefits

The combination of high‑alloy HSS and elevated hardness makes the component suitable for turning a range of steels and alloyed materials where heat generation is a limiting factor. The material’s characteristics enable secure roughing and finishing passes without premature softening. As a precut, ground square bar, it eliminates the initial material‑preparation step for many shop processes, delivering a ready‑to‑mount solution that supports both small‑batch and larger production runs.

Quality assurance and operational integration

Supplied to DIN 4964 Form B, the blank is hardened, tempered and finish ground, with ends left straight and unground to allow custom end machining if required. The controlled manufacturing process and traceable material designation (1.3207) provide confidence in repeat orders and component interchangeability. For procurement and inventory planning, the unit comes packaged as a single piece per pack, facilitating straightforward stock management and predictable consumption.

FAQ

What materials is this turning blank suitable for?
The turning blank from Werner Wilke, made of HSS‑EW9Co10, is suitable for machining a variety of steels and alloyed materials where high cutting temperatures may occur.

How does the 10% cobalt content affect performance?
The 10% cobalt alloy increases red‑hardness and wear resistance, so the Wilke blank maintains cutting performance under thermal load better than standard HSS.

What dimensional tolerances can be expected?
The square cross section is supplied to h13 tolerance and the length is specified as 200 mm with a ±2 mm length tolerance, ensuring reliable clamping and repeatability.

Are the ends ready for immediate clamping in collets or chucks?
The piece is delivered with straight, finish‑ground ends; the ends are unground where specified, allowing secure clamping and optional final machining if required.

Is material traceability available for repeat orders?
Yes, the material designation 1.3207 and the DIN 4964 Form B specification support consistent quality and traceability for ongoing procurement.
