Take advantage of a hardened, finish‑ground rectangular bar in HSS‑EW9Co10 with 10% cobalt and a nominal cross‑section of 16 × 8 mm, offering reliable wear resistance (65–69 HRC) and consistent dimensional control (tolerance h13, length ±2 mm) for precision turning applications; order the turning bar directly via Metav Werkzeuge or ask the consultants if technical clarification is needed.

Turning bar (DIN 4964 Form D) – HSS‑EW9Co10, 16×8 mm, 200 mm, Werner Wilke

The turning bar (DIN 4964 Form D) is a hardened, rectangular bar stock produced in HSS‑EW9Co10 for demanding turning and toolmaking tasks where high hardness and thermal stability are essential.

• HSS with 10% cobalt for heat resistance
• Rectangular section 16 × 8 mm, DIN 4964 Form D
• Hardness 65–69 HRC for wear resistance
• Length 200 mm with h13 cross‑section tolerance

Precision and material performance for consistent machining

The combination of HSS‑EW9Co10 and a 10% cobalt alloy delivers elevated red hardness and improved toughness compared with conventional high‑speed steels. This material choice ensures the bar maintains cutting edge integrity and dimensional stability at higher operating temperatures, which translates into fewer tool failures and longer service intervals. The 65–69 HRC hardness rating provides a balance between wear resistance and fracture toughness, making the bar suitable for repeatable production tasks and small‑batch tool fabrication where hard, wear‑resistant blanks are required.

Dimensional control that supports predictable results

A rectangular profile of 16 × 8 mm with h13 cross‑section tolerance and a length of 200 mm (length tolerance ±2 mm) supports accurate setup and predictable clamping in machining fixtures. The DIN 4964 Form D designation standardises the geometry for compatibility with common chucks and holders. Finished tolerances reduce preparation time on the lathe and limit trial cuts, helping to increase first‑pass accuracy. Ends are supplied straight and unground, allowing workshop workflows to choose their preferred end preparation without masking the bar's finished body.

Surface condition and heat treatment for durable blanks

The blank is supplied hardened, tempered and finish‑ground, which yields a stable core and a uniform surface finish across the bar length; this minimises local stress risers and eases precision gripping. While the ends are intentionally left unground, the body’s finish grinding supports precise locating and consistent friction behaviour in collets or bespoke clamping systems. The material designation 1.3207 identifies the steel grade in recognised European standards, helping to match tooling strategies and heat‑treatment expectations in production planning.

Practical benefits for workshop and production environments

Using bar stock with defined hardness and tolerances reduces process variation and downstream rework. The combination of heat resistance, tight geometric tolerances and a rectangular form delivers shorter setup times, longer tool life and improved repeatability for turning operations and tool blank manufacturing. For engineers and machinists who value reliability, such blanks make it easier to plan maintenance intervals and calculate life‑cycle costs, strengthening both productivity and quality assurance in small and medium production runs.

FAQ

What applications is this bar suitable for?
The turning bar in HSS‑EW9Co10 is intended for precision turning, tool blanks and small‑batch component production where elevated hardness (65–69 HRC) and thermal stability are required; the SKU is 4118420110NW.

Can the bar be used for hardened‑steel machining inserts?
Yes, the high cobalt content and hardness make the material suitable as a basis for machining inserts and tool blanks that demand wear resistance and dimensional stability during finishing.

How precise is the rectangular section of the bar?
The cross‑section is manufactured to h13 tolerance, providing consistent 16 × 8 mm geometry suitable for predictable clamping and minimal corrective machining.

Are the ends ready for immediate clamping in collets?
The body is finish‑ground, but the ends are supplied straight and unground so workshops can perform preferred end preparation; the bar’s finished surfaces remain suitable for accurate locating.

What standard and material designation apply to this product?
The bar conforms to DIN 4964 Form D and carries the material designation 1.3207 for clear reference in production documentation.
