Turning blank DIN 4964 Form B — square 8 x 8 mm, HSS-EW9Co10, 100 mm (Wilke)

A turning blank (DIN 4964, Form B) designed as a square bar for precision turning and small-part machining applications

• Hardened to 65–69 HRC
• Square 8 x 8 mm section h13
• Material HSS‑EW9Co10, 10% cobalt
• Length 100 mm, ends unground

Robust core for demanding turning operations

The supply-grade square bar is manufactured from HSS‑EW9Co10 (material number 1.3207) and delivered hardened, tempered and finish-ground along its profile. This high-speed steel alloy, with a 10% cobalt content, increases red‑hardness and wear resistance, which translates into longer tool life under elevated cutting temperatures. For workshops producing small batches or intricate parts, the hardened condition of this workpiece blank provides a stable base material that reduces variability in subsequent turning, drilling and finishing steps.

Why the heat treatment and hardness matter in practice

A surface hardness of 65–69 HRC ensures dimensional stability during secondary machining and supports tight edge retention when tools are used to form or finish features. Heat treatment followed by tempering prevents brittleness while maintaining cutting performance. For engineers evaluating blank materials, this combination reduces rework rates and makes the component behaviour more predictable during high‑speed or interrupted cuts, thereby improving process reliability and cycle‑time estimates.

Dimensional accuracy explained for reliable production planning

The square section is specified as 8 x 8 mm with a cross‑section tolerance of h13 and a length of 100 mm; length tolerance is ±2 mm. The bar is finished along its length but has straight, unground ends, which eases clamping and reduces unnecessary material removal during set‑up. The adherence to DIN 4964 (Form B) offers compatibility with standard fixtures and collets used in toolrooms and CNC lathes, allowing smooth integration into existing production flows without custom fixturing.

Practical application and handling recommendations

As a compact square bar, this workpiece blank is suitable for precision turning, toolmaking blanks and prototypes where a small square cross section is required. The lack of a surface coating and the natural finish mean conventional cutting fluids and standard high‑speed turning inserts are appropriate; machinists will benefit from optimising speeds to account for the HSS‑EW9Co10 alloy’s thermal properties. When planning stock removal, consider the hardness band to select suitable cutting geometries and coolant strategies to prolong insert life.

FAQ

What materials is this turning blank made from?
The turning blank is produced from HSS‑EW9Co10 (material number 1.3207), a high‑speed steel alloy containing approximately 10% cobalt for enhanced heat resistance.

Is the bar suitable for standard lathe chucks and collets?
Yes; being DIN 4964 Form B with an 8 x 8 mm square section and h13 tolerance, the blank suits common square‑holding fixtures and can be clamped in many standard collet systems with appropriate adapters.

How does the hardness affect machining strategy?
With a hardness of 65–69 HRC, the blank requires appropriate cutting geometries and coolant use; the high hardness provides wear resistance but needs rigid set‑up and suitable carbide or ceramic tooling for efficient material removal.

Are the ends ground for precision seating?
The bar profile is finish‑ground along its length, but the ends are supplied straight and unground, simplifying initial fixturing while allowing the final end faces to be machined to specific tolerances if needed.

Can this blank be used for prototype and small‑batch production?
Yes; its compact 100 mm length and precise section make it well suited for prototyping, small runs and toolroom applications where consistent material properties and dimensional predictability are required.
