Wilke turning blank DIN 4964 Form A Ø 8 mm – solid turning stock, HSS‑EW9Co10, 100 mm

Wilke turning blank DIN 4964 Form A Ø 8 mm is a solid round turning blank intended for precision machining and tool production, manufactured from high‑alloy high‑speed steel.

HSS‑EW9Co10 with 10% cobalt for strength Hardened 65–69 HRC for wear resistance Round DIN 4964 Form A, ready for turning Diameter tolerance h8 for concentric accuracy

Durable high‑alloy steel for longer tool life

The blank is produced from High‑speed steel HSS‑EW9Co10, a high‑alloy tool steel containing 10% cobalt, which improves red hardness and resistance to thermal softening during machining. The elevated hardness level of 65–69 HRC provides exceptional wear resistance, meaning less frequent regrinding or replacement and more stable cutting geometries over longer production runs. For non‑specialist readers, HRC denotes the Rockwell hardness scale used for tool steels; a higher value indicates a harder, more wear‑resistant material. This combination of material and hardness is valuable where uniform performance and tool life directly influence part quality and process economy.

Precision dimensions and tolerances for reliable machining

Manufactured to DIN 4964 Form A, the blank is supplied as a round bar with a nominal Ø 8 mm and a total length of 100 mm, with diameter tolerance h8 and a length tolerance of ±2 mm. The precision ground finish on the length ensures improved concentricity and predictable clamping behaviour in collets and chucks. The ends are supplied straight and unground, allowing final facing or machining to suit specific fixture setups. The listed tolerances and standard ensure compatibility with industrial turning workflows and support reproducible component geometries where runout and concentricity are critical.

Practical use and handling in production environments

This solid turning stock is intended as a basis for producing turned parts or tool components in workshops and small‑batch production. The combination of high‑alloy HSS and the specified heat treatment provides a stable starting blank for operations that demand dimensional stability under cutting heat. When setting up, consider finishing the ends and verifying clamping diameters to exploit the h8 tolerance for best rotational accuracy. For process planning, note that the supplied condition—hardened and ground—means the blank is not intended for heavy forming but for precision turning and finishing where tool life and reproducibility matter.
