WILKE turning blank DIN 4964, Form B — 20 x 20 mm, HSS‑EW9Co10, L 200 mm

WILKE turning blank DIN 4964 Form B is a square, hardened and finish‑ground high‑speed steel bar intended for precision turning and small‑batch production.

• Hardened to 65–69 HRC for long tool life
• Square cross‑section 20 x 20 mm, tolerance h13
• High‑speed steel HSS‑EW9Co10 with 10% cobalt
• Finished ground length 200 mm, tolerance ±2 mm

Longer service life through heat treatment and alloying

The HSS‑EW9Co10 alloy, with a 10% cobalt content, increases red hardness and wear resistance compared with conventional high‑speed steels. Combined with a 65–69 HRC hardness after hardening and tempering, this material choice reduces flank wear under elevated cutting temperatures and extends in‑service life. For production planners, this equates to fewer tool changes and improved process stability during prolonged machining cycles.

Predictable dimensions that speed up setup

A 20 x 20 mm square cross‑section with h13 tolerance and a length of 200 mm (length tolerance ±2 mm) provides consistent reference surfaces for chucking and clamping. The finish‑ground condition ensures straight, machinable faces, lowering set‑up times and minimising adjustment during first‑piece runs. Reliable dimensional control supports reproducible part quality in serial turning and reduces scrap rates.

Material designation and standards for correct specification

Provided in accordance with DIN 4964, material number 1.3207 indicates a recognised high‑speed steel grade suitable for a wide range of turning tasks. The specification clarifies metallurgical properties to purchasing and quality departments, enabling straightforward material comparisons and compliance checks. The hardened and finish‑ground delivery state simplifies integration into existing machining workflows without additional heat treatment.

Practical advantages on the shop floor

Delivered as a square turning blank with straight, unground ends, this bar is ready for facing, centre drilling and clamping. The combination of finish grinding and a robust cobalt‑enriched matrix supports stable cutting conditions when machining alloyed steels and other demanding materials. Reduced tool wear and steady cutting forces translate into predictable cycle times and a more efficient production rhythm.
