Turning blank DIN 4964 Form D — HSS‑EW9Co10, 8×5 mm, 160 mm

The turning blank DIN 4964 Form D is a hardened, ground and tempered rectangular blank for precision toolmaking and turning applications, supplied in a 160 mm length ready for further machining.

• Hardened 65–69 HRC for wear resistance
• Rectangular Form D, cross-section 8×5 mm
• Ground and tempered, ends straight and unground
• Length 160 mm, length tolerance ±2 mm

Consistent performance through material and heat treatment

Manufactured from HSS‑EW9Co10 (Werkstoffnummer 1.3207) with a 10% cobalt content and a hardness of 65–69 HRC, this blank delivers high wear resistance and heat tolerance under heavy cutting conditions. The combination of high-speed steel alloying and targeted heat treatment produces a workpiece that sustains cutting edges longer and minimises premature deformation; as a result, downstream tool grinding and finishing cycles remain predictable and repeatable. The delivered state—ground and tempered—means less preparatory machining is required before tool geometry is applied, shortening lead times in production.

Precision tolerances that reduce setup time and reject rate

With a rectangular cross-section of 8×5 mm and a cross-section tolerance of h13, the blank supports reliable clamping and uniform material removal across batches. A length of 160 mm with a ±2 mm length tolerance ensures consistent fixturing and repeatable positioning in grinding jigs and lathes. These measurable tolerances translate into fewer adjustments during setup, reduced scrap, and faster cycle-to-cycle reproducibility. Reference to DIN 4964 signals conformity with recognised standards for turned blanks, simplifying quality documentation and acceptance in workshop environments.

Practical design for efficient tool production

The ends are supplied straight and unground, allowing flexible final-length decisions or customised end treatments before final grinding; this simplifies logistics for toolmakers who require specific end preparations. The combination of a rectangular Form D profile and the blank’s ready-machined surface supports immediate processing on standard tool grinders and CNC lathes. For operations prioritising throughput, the material choice and finish reduce the need for extensive preparatory operations, contributing to lower overall production time and predictable tool life.
