Wilke turning blank (DIN 4964 Form D) — HSS‑EW9Co10 rectangular bar, 12 x 8 mm, 160 mm

The Wilke turning blank is a hardened, finished rectangular bar for reliable preparation of lathe tooling and small turned components

• HSS‑EW9Co10 with 10% cobalt content
• Rectangular section 12 x 8 mm h13 tolerance
• Hardened and finished, 65–69 HRC
• Length 160 mm, length tolerance ±2 mm

Extended tool life through cobalt‑alloyed high‑speed steel

The HSS‑EW9Co10 composition, containing 10% cobalt, increases red hardness and resistance to heat, which translates into longer tool life under cyclic cutting loads. In practise this means fewer tool changes and steadier production runs when working in medium to high cutting speeds. The material’s combination of toughness and wear resistance makes it suitable as a reliable raw material for small turning tools and indexable insert holders where thermal stability is required.

Accurate section and tolerances reduce setup time

A consistently produced rectangular section of 12 x 8 mm with h13 cross‑section tolerance and ±2 mm length tolerance minimises reworking and alignment time at the machine. The finished geometry supports repeatable clamping in standard toolholders and vises, reducing setup variance and scrap rates. The bar’s dimensional control contributes directly to process stability, especially in batch production of small turned parts.

Ready‑to‑process condition for predictable machining results

Delivered hardened and finished, with 65–69 HRC hardness and ends straight and unground, this turning blank arrives ready for secondary machining and precise finishing. The combination of final grinding and straight ends allows reliable reference surfaces for datum setting while leaving end faces available for bespoke facing or pre‑grinding operations. The material identification Werkstoffnummer 1.3207 provides a traceable basis for selecting cutting data and coolant strategy.

Practical advantages in workshop workflows

Using a standardised DIN 4964, Form D rectangular bar simplifies inventory and tooling choices across a workshop or small production line. The 160 mm nominal length and robust alloy composition reduce the frequency of emergency replacements and support scheduled maintenance intervals. Where uniformity and repeatability are priorities, this type of turning blank helps maintain throughput without compromising part quality.

FAQ

What applications is this turning blank suitable for?
The Wilke turning blank (turning blank, SKU 4118420100NW) is intended for manufacture of small lathe tools and components that require a hardened HSS‑EW9Co10 core and stable rectangular geometry.

Can the bar be used at higher cutting speeds?
Yes, the cobalt‑enriched HSS‑EW9Co10 composition improves red hardness, so the turning blank performs better at elevated cutting temperatures compared with standard HSS.

How precise are the dimensions out of the factory?
Dimensional control is provided by the h13 cross‑section tolerance and a length tolerance of ±2 mm, ensuring repeatable clamping and predictable set‑up.
