WILKE turning blank DIN 4964 Form A – Ø 5 mm, HSS-EW9Co10

WILKE turning blank DIN 4964 Form A – Ø 5 mm, HSS-EW9Co10 is a hardened, finish-ground round bar designed as a precision blank for turning and small-part production, compliant with DIN 4964 Form A for consistent geometry and machinability.

• Hardened and finish-ground, 65–69 HRC
• Solid HSS-EW9Co10 with 10% cobalt
• Ø 5 mm, tolerance h8
• Length 80 mm, length tolerance ±2 mm

Precision material for reliable tool life and repeatable results

The HSS-EW9Co10 composition with 10% cobalt delivers elevated hot hardness and wear resistance compared with standard high-speed steels, making it suitable where toughness and abrasion resistance are required. The blank is hardened, tempered and finish-ground, resulting in a uniform microstructure and surface that reduces variation between batches. For production environments this translates into fewer tool changes, predictable tool life and improved process stability when fabricating turned components from a range of commonly used metals.

Dimensional accuracy that simplifies set-up and inspection

Produced to DIN 4964 Form A, the round bar is supplied with Ø 5 mm diameter and a tolerance of h8, plus a length of 80 mm with a ±2 mm length tolerance. The combination of diameter tolerance h8 and finish grinding ensures good concentricity and consistent clamping behaviour in chucks and collets, which supports higher first-pass yields. The ends are supplied straight and unground, allowing final facing or custom end preparation to match specific mounting or assembly needs while keeping the core geometry stable.

Workshop efficiency and compatibility with precision turning operations

Delivered as a ready, finish-ground blank, the component minimises preparatory processing for small-batch work and prototype runs. The high hardness range (65–69 HRC) reduces the tendency for plastic deformation during clamping and offers a stable base for downstream grinding or turning operations. Specified as material number 1.3207, this round bar is a compact option for toolmakers, model engineers and precision workshops that demand reproducible starting stock for tight-tolerance parts. Clear material and hardness specifications aid in selecting appropriate cutting data and coolant strategies to achieve the desired surface finish.

FAQ

What is the material composition and why does it matter?
The WILKE turning blank is made from HSS-EW9Co10 (material no. 1.3207) and contains 10% cobalt, which increases red hardness and wear resistance; this helps maintain cutting edge and dimensional stability under elevated cutting temperatures.

Which tolerances and dimensions are specified for the blank?
The blank (SKU 4118401040NW) is supplied as Ø 5 mm with tolerance h8 and a length of 80 mm with a ±2 mm tolerance; hardness is specified at 65–69 HRC.

Are the ends ready for immediate clamping or is additional preparation required?
Ends are delivered straight and unground, so final facing or end preparation is typical to achieve specific concentricity or clamping requirements before precision finishing operations.

Which standard does this blank conform to and how does that help in production?
The round bar conforms to DIN 4964 Form A, which ensures consistent geometry and interchangeability when used as a starting blank for turning and precision machining.
