200mm Rectangular HSS-EW9Co10 Ground Hardened Bar 20 x 5 h13, 65-69 HRC - Werner Wilke Zerspanungstechnik GmbH

Take advantage of a hardened, ground HSS stock with a precise rectangular cross-section for consistent clamping and predictable machining performance; the HSS‑EW9Co10 composition with 10% cobalt and a 65–69 HRC hardness ensures thermal stability and extended tool life, while the 20 × 5 mm section and ±2 mm length tolerance support reliable set-ups — order the turning blank directly via Metav Werkzeuge or consult the specialists if clarification is required.

Rectangular turning blank, Form D — HSS‑EW9Co10, 20 × 5 × 200 mm (WILKE)

The rectangular turning blank Form D is a hardened and finish‑ground HSS stock compliant with DIN 4964, intended for precision toolmaking and workshop turning applications with a 20 × 5 mm cross‑section and a 200 mm length

• Hardened and ground, 65–69 HRC
• Rectangular cross-section 20 × 5 mm
• High-speed steel HSS‑EW9Co10, 10% cobalt
• Dimensional tolerance h13, length ±2 mm

Predictable geometry for precise tool blanks

The blank is supplied as a rectangular turning bar manufactured to DIN 4964 Form D, offering a consistently machined cross‑section of 20 × 5 mm and a nominal length of 200 mm. The controlled h13 cross‑section tolerance together with the ±2 mm length tolerance minimises set‑up variability when mounting or indexing the stock in fixtures. These characteristics translate into shorter preparation times and reproducible machining results when producing custom cutting tools, single‑point profiles or small components from a uniform HSS base. The straight, unground ends facilitate quick clamping without unexpected misalignment, supporting efficient workflows in small and medium toolrooms.

Material composition for stability under heat and wear

Made from HSS‑EW9Co10 (high‑speed steel with 10% cobalt) and hardened to 65–69 HRC, the material combines elevated red hardness with enhanced wear resistance. The cobalt alloying improves hot hardness, which helps maintain edge and surface integrity during finishing passes and when cutting at raised temperatures. For operations where thermal stability and a long service interval are required, this grade reduces frequency of regrinds and component rejection, delivering a measurable benefit to process reliability and total cost of ownership. The finish‑ground condition ensures a consistent surface for subsequent profiling or grinding steps.

Seamless use in toolmaking and workshop production

Supplied as a single unit and finished for immediate processing, the blank is suitable as a raw form for producing profiles, tool bits and turned parts where a rectangular HSS substrate is required. The combination of Form D geometry and the finish quality supports straightforward indexing, safe clamping and predictable material removal during tool grinding or single‑point turning. Shops that standardise on repeatable blanks benefit from reduced inspection cycles and faster downstream machining. For specification checks or bespoke requirements, Metav Werkzeuge can advise on compatibility with existing fixtures and recommend suitable quantities for workshop stock.

FAQ

What material is the blank made from and what does that mean for machining?
The turning blank is manufactured from HSS‑EW9Co10, a high‑speed steel with 10% cobalt; this composition provides improved hot hardness and wear resistance compared with standard HSS, making it well suited to finishing operations and longer tool life.

What are the exact dimensions and tolerances of the stock?
The blank has a cross‑section of 20 × 5 mm and a nominal length of 200 mm; dimensional tolerances are h13 for the cross‑section and ±2 mm for the length.

Is the blank supplied ready for grinding and profiling?
Yes, the piece is hardened, tempered and finish‑ground, with straight, unground ends to allow quick clamping and efficient subsequent profiling or grinding processes.

Can this HSS grade be used for cutters intended to work at high cutting temperatures?
The 10% cobalt content in HSS‑EW9Co10 increases resistance to softening at elevated temperatures, so the material is a suitable basis for tools and cutters that encounter higher thermal loads.

What standard and form does the blank conform to?
The product complies with DIN 4964 and is supplied in Form D rectangular geometry, which is a recognised specification for turning blanks used in toolmaking and workshops.
