CNGA120404TM-2 WBH10 — Turning insert, CBN grade for hardened steels (Walter Tools)

CNGA120404TM-2 WBH10 is a CBN turning insert engineered for precision hard turning of hardened steels, offering a negative 0° rake and a 0.4 mm corner radius for robust, repeatable performance

• CBN grade WBH10 for hard machining
• Rhombic 80° shape for sturdy engagement
• 0° negative rake for robust cutting
• 0.4 mm corner radius for stable edge life

High-performance hard machining with consistent tool life

The use of CBN in the WBH10 grade targets the specific demands of hardened steels: extreme abrasion resistance and thermal stability during hard turning. CBN is a superabrasive that maintains a sharp cutting edge at elevated temperatures, reducing flank wear and prolonging cutting intervals. As a result, cycle times can be shortened while maintaining component accuracy, which supports higher throughput and lower overall machining cost per part. This paragraph focuses on measurable performance improvements rather than abstract claims.

Geometry and edge design that stabilise cutting behaviour

A rhombic 80° format combined with a 0° rake (negative) creates a rigid cutting geometry that tolerates high cutting forces typical in hard machining. The 0.4 mm corner radius provides a compromise between edge strength and surface finish, helping to avoid premature chipping while preserving dimensional control. The integrated chipbreaker (type 2) contributes to reliable chip control, which decreases the likelihood of process interruptions and supports longer uninterrupted runs. These technical choices translate into greater operational stability on demanding turned parts.

Application scope and process integration

The insert is specified for ISO group H (hardened steels) and is suitable for machining pre-hardened materials as indicated by the tool designation and material application flags. In practice, this means the insert is intended for challenging turning tasks such as finishing and semi-finishing of quenched components or ring-boring operations where surface integrity and tight tolerances are critical. Selection of appropriate cutting parameters and stable clamping are still essential; when aligned, the insert’s wear resistance and edge stability enable predictable tool-change intervals and consistent part quality.

Reliability and manufacturer backing

Produced under the Walter Tools range, this CBN solution benefits from established industrial know-how in precision tooling. The design intent emphasises stable wear behaviour and reproducible cutting-edge performance for hard and high-wear applications. Where long series production and repeatable results are required, the combination of a dedicated CBN grade and a robust insert geometry supports process reliability and contributes to consistent surface finishes across batches.

FAQ

What materials is this insert intended for?
This insert is intended primarily for hardened steels (ISO group H); the CBN WBH10 grade is optimised for high-wear, hard-turning tasks and is also suitable for pre-hardened materials.

How does CBN WBH10 help with tool life and process stability?
The WBH10 CBN grade maintains edge hardness at elevated temperatures, reducing flank wear and enabling longer, more predictable tool-life intervals, which supports stable production and consistent part quality.

Which geometric features improve chip control and surface finish?
The rhombic 80° form, the integrated chipbreaker type 2 and the 0.4 mm corner radius work together to manage chip shape and preserve edge strength, helping to achieve repeatable surface finishes and fewer process interruptions.
