Turning blank DIN 4964 Form D – HSS‑EW9Co10, 25 x 12 x 160 mm (WILKE)

The turning blank DIN 4964 Form D is a rectangular, hardened and finish-ground HSS bar intended for the production of precision cutting tools and small tool shanks in toolrooms and manufacturing environments

• HSS‑EW9Co10 with 10% cobalt
• Rectangular cross-section 25 x 12 mm
• Hardened 65–69 HRC, finish-ground
• Cross-section tolerance h13, length ±2 mm

Durable, high-performance material that reduces tooling costs

The blank is manufactured from HSS‑EW9Co10 (material number 1.3207), an alloyed high-speed steel with 10% cobalt that raises hot hardness and wear resistance compared with standard HSS. The elevated hardness (65–69 HRC) increases component life for ground cutting edges and reduces the frequency of tool regrinds, which directly lowers cost per part. For workshops producing small series or bespoke tools, this composition offers measurable savings through extended service intervals and consistent edge retention.

Precise dimensions for predictable setup and minimal rework

Supplied in a rectangular cross-section (25 x 12 mm) with cross-section tolerance h13 and length 160 mm ±2 mm, the workpiece keeps setups predictable and repeatable. The combination of finish-ground surfaces and defined tolerances simplifies fixture design and reduces the need for additional preparatory milling. With ends supplied straight and unground, the blank is ready for clamping or for final end preparation according to the intended application, supporting efficient machine set-up and a faster throughput in both manual and CNC toolmaking operations.

Ready-to-process condition for versatile workshop applications

Delivered hardened, tempered and finish-ground, the component is prepared for final shaping by grinding or fine turning rather than heavy stock removal, which suits modern toolroom workflows. The DIN 4964 Form D designation ensures conformity with established standards for rectangular tool blanks, aiding compatibility with existing toolholders and toolmaking jigs. Typical uses include production of bespoke lathe tools, form tools, small insert holders and precision tool shanks where uniform hardness and dimensional stability are essential.

Practical processing notes for safe and effective use

Given the high hardness rating, shaping is commonly performed by grinding and fine machining; conventional heavy cutting may induce chipping. The HSS‑EW9Co10 composition affords improved resistance to thermal softening, so appropriate coolant and abrasion-resistant grinding media extend service life. The blank is supplied per unit and marked with SKU for traceability; keep parts organised to maintain batch consistency and to support quality assurance processes in production.

FAQ

What material is the blank made from and what are the benefits of that alloy?
The blank is produced from HSS‑EW9Co10 (1.3207); the 10% cobalt content improves hot hardness and wear resistance, giving the turning blank superior edge retention for cutting-tool production.

Is the workpiece ready for immediate toolmaking after delivery?
Yes, the WILKE turning blank is hardened, tempered and finish-ground, which means it is prepared for final shaping operations such as grinding and fine machining rather than heavy stock removal.

Which tolerances can be expected for cross-section and length?
Cross-section tolerance is h13, and length tolerance is ±2 mm; these dimensional specifications support predictable set-up and reduce the need for corrective rework.

For which applications is this rectangular blank particularly suited?
The material and finish make it suitable for manufacture of precision lathe tools, small tool shanks, form tools and other cutting-tool components where stable hardness and wear resistance are required.

How should the blank be processed given its hardness?
Due to the 65–69 HRC hardness, recommended processing methods include grinding and fine finishing; the SKU 4118420149NW should be used for traceability and batch control during tool production.
