CCGW09T304TM-2 WBH20 – CBN turning insert for hardened steels, Rhombus 80° · Walter Tools

The CCGW09T304TM-2 WBH20 is a CBN-grade indexable insert designed for hard turning and finishing operations on high-hardness materials, combining the robustness of a CBN cutting edge with a versatile rhombic geometry for stable chip control and reproducible surface quality.

• CBN grade WBH20 for hard turning
• Rhombic 80° shape for versatile cutting
• 7° clearance angle for stable cutting
• 0.4 mm corner radius for fine finishing

Consistent hard-turning performance for productivity gains

The CBN-based grade WBH20 is engineered for demanding, high-wear operations on hardened steels and similarly challenging materials. As a superhard cutting material, CBN resists abrasive wear and maintains a stable cutting edge under elevated temperatures and cutting forces. This behaviour reduces flank wear and preserves component tolerances over longer tool life, which in turn lowers tooling costs per produced part and helps sustain uninterrupted production cycles. The combination of a Rhombus 80° form and the CBN grade provides a balance between edge strength and directionality, enabling both light finishing cuts and more aggressive stabilised passes where appropriate.

Geometry and micro-geometry that deliver precision and surface quality

The insert’s 0.4 mm corner radius and 7° relief angle contribute directly to surface integrity and process stability. A finer corner radius supports improved surface finishes when finishing hardened components, while the modest clearance angle reduces rubbing and thermally induced edge degradation. The rhombic outline gives a reliable cutting orientation for facing and turning operations where repeatable geometry is essential. These geometric choices mean less rework and more consistent first-pass acceptance rates, an important factor in high-precision production environments.

Application scope, handling and economy

This grade and geometry are particularly suited to machining tasks categorised as hard turning and pre-hardened steel finishing; the insert is part of the Walter CBN series and intended specifically for wear-intensive tasks. Where hardness and edge retention are decisive, this insert reduces the frequency of tool changes and supports higher process stability. For workshop planning, the insert’s characteristics help to define predictable tool life and enable more accurate cost-per-component calculations for production runs involving hardened materials.
