Turning bar DIN 4964 Form B — 12 x 12 mm HSS‑EW9Co10, 200 mm (WILKE)

The turning bar DIN 4964 Form B is a hardened, finish‑ground square stock designed for precision lathe and toolroom applications where dimensional stability and elevated wear resistance are required.

• HSS‑EW9Co10 high‑speed steel with 10% cobalt
• Hardened and tempered, 65–69 HRC
• Square 12 x 12 mm precision ground stock
• Length 200 mm with ±2 mm length tolerance

Consistent hardness for durable turning blanks

The combination of HSS‑EW9Co10 and a specified hardness of 65–69 HRC ensures high resistance to abrasion and thermal softening under intermittent cutting loads. For operations that demand prolonged tool life and repeatable results, this hardened and tempered square stock reduces the frequency of rework and replacement. The metallurgical grade 1.3207 describes a robust high‑speed steel alloy with a 10% cobalt share, which improves red hardness and wear behaviour during elevated cutting temperatures.

Precision dimensions that support accurate part production

With a 12 x 12 mm cross‑section produced to h13 tolerance and a nominal length of 200 mm, the blank provides clear dimensional reference for chucking and clamping. The declared length tolerance ±2 mm minimises setup variation for short‑run turning and toolmaking tasks. The DIN 4964 Form B specification and finish‑ground body allow straightforward integration into jigs and fixtures, while the square geometry simplifies centring and ensures a repeatable datum for downstream machining.

Practical machining and finishing advantages

The stock is supplied finish‑ground, with ends that are straight but unground, allowing users to establish custom datum faces or to perform final face machining as required. The hardened condition is suited to applications where blanks are reshaped, ground or partially turned to create precision components. Because of the alloy composition and heat treatment, the material maintains cutting performance under higher thermal loads; this is particularly beneficial when producing small, high‑precision parts that require tight surface quality and consistent mechanical properties.

Quality assurance and workshop reliability

Manufactured to DIN 4964 and checked for cross‑section tolerance, the blank offers a verifiable basis for procurement decisions in workshops and small production environments. The square turning stock reduces the need for additional clamping accessories in many fixtures and contributes to a predictable production flow. Paired with Metav’s distribution and product range, the item supports a streamlined supply process for precision engineering tasks without compromising on material integrity or traceability.

FAQ

What material is the blank made from and what are its key properties?
The turning bar is produced from HSS‑EW9Co10 (material number 1.3207), an alloyed high‑speed steel with 10% cobalt; this composition provides improved red hardness and wear resistance for the hardened condition.

What does the stated hardness of 65–69 HRC mean for machining?
A hardness of 65–69 HRC indicates a high wear‑resistant condition; the turning bar DIN 4964 Form B should be used where durability is required and where final machining or grinding is planned, rather than extensive rough cutting.

How precise are the dimensions and what tolerances apply?
The square stock is 12 x 12 mm to h13 cross‑section tolerance, with a nominal length of 200 mm and a length tolerance of ±2 mm, providing consistent sizing for fixture and chuck setups.

Why are the ends supplied straight but unground?
Ends are supplied unground to allow users to establish their own datum faces or to perform final facing operations; the body is finish‑ground to ensure accurate cross‑section and surface condition for clamping and indexing.

Is this product suitable for toolroom and small production runs?
Yes; the hardened, finish‑ground turning bar is intended for precision turning and toolmaking tasks where repeatability and wear resistance support short to medium production sequences.
