DCGW11T304TM-2 WBH20 – CBN turning insert, Rhombic 55°, 7° clearance (Walter Tools)

A DCGW11T304TM-2 WBH20 turning insert engineered for high‑performance hard machining of hardened steels and comparable high‑wear materials

• CBN grade WBH20 for hard materials
• Rhombic 55° geometry for versatile turning
• 7° clearance angle for stable cutting
• 0.4 mm nose radius for precise finishes

Consistent tool life for hard machining

The use of CBN (cubic boron nitride) in the WBH20 grade provides exceptional wear resistance, which is critical when working with hardened steels. This insert is designed to maintain a stable cutting edge under high thermal and mechanical load, so machining cycles run with fewer interruptions. The result is a predictable tool life and reduced downtime, which supports continuous production and cost efficiency in demanding turning operations.

Geometry tuned for dimensional accuracy

The Rhombic 55° shape and a 0.4 mm nose radius enable accurate profile generation while balancing strength at the cutting edge. Combined with the 7° clearance, the geometry reduces rubbing and ensures reliable chip formation, improving surface finish and dimensional control. These features help achieve consistent part quality with minimal rework, particularly when tight tolerances are required.

Suitable for hardened and pre‑hardened steels

Classified for applications with hardened steels, this grade is a practical choice for hard turning and finishing of components that would rapidly wear conventional carbide inserts. The WBH20 composition is optimised for stable chip control and long life in high‑hardness environments, making it suitable where repeatability and process security are essential. The insert’s specifications align with ISO group H machining demands.

Economic advantages through fewer tool changes

By reducing the frequency of insert changes and maintaining a consistent cutting edge, the insert contributes to lower operating expenses and higher throughput. Improved durability means less setup time and fewer tool inventories to manage. For machining centres producing hardened parts, this translates into measurable gains in productivity and a clearer return on tooling investment.
