Turning blank DIN 4964 Form D — rectangular 25 x 6 mm, HSS-EW9Co10 (WILKE)

The Turning blank DIN 4964 Form D is a rectangular precision bar intended for demanding turning and finishing tasks in toolrooms and small-batch production

• HSS-EW9Co10 with 10% cobalt content
• Rectangular Form D to DIN 4964
• Hardened and finish-ground, 65–69 HRC
• Cross-section 25 x 6 mm, length 200 mm

Durable hardness for repeatable, precision work

The use of HSS-EW9Co10 and a hardness of 65–69 HRC delivers a turning blank that resists deformation during clamping and post-machining operations. Such elevated hardness reduces the risk of work-hardening under pressure and maintains geometric stability during light rework or finishing. The result is consistent dimensional accuracy across batches and fewer set-up checks, which supports efficient small-series production and predictable downstream processes.

Alloy and performance: why 10% cobalt matters

The 10% cobalt content in the high-speed steel matrix increases red hardness and edge retention under thermal stress. This material composition enables higher cutting temperatures without rapid softening, making the bar well suited for precision turning where sharp, stable edges are required after finishing passes. In practice, this means longer intervals between regrinding and a better surface integrity on turned components when using appropriate tooling and feeds.

Accurate tolerances for easier clamping and finishing

Dimensional control is built into the product: cross-section tolerance h13 and a length tolerance of ±2 mm allow reliable fixturing and repeatable set-ups. The blank is supplied hardened, tempered and finish-ground, with straight, unground ends that facilitate secure clamping or custom facing prior to final machining. These attributes reduce adjustment time on the lathe and simplify quality checks during first-off inspections.

Practical integration into workshop workflows

Supplied as a single unit and conforming to DIN 4964, this rectangular bar is straightforward to store and handle in a workshop environment. The finish-ground condition minimises immediate preparatory machining, while the unground ends allow tailored end-processing to match specific chucking or fixture systems. Technical data and the SKU are available for ordering and inventory management, and documentation can be provided to support quality records and traceability.
