CNGA120404TM-2 WBH10C Drehwendeschneidplatte — CBN grade for hardened steel, Rhombus 80° | Walter Tools

The CNGA120404TM-2 WBH10C is a rhombic 80° indexable insert with a coated CBN grade, designed for productive hard turning and the machining of hardened steels

• Coated CBN grade WBH10C
• Rhombic 80° insert geometry
• 0° negative rake for stability
• Corner radius 0.4 mm for surface finish

High-performance turning for hardened components

The insert combines a coated CBN grade with a robust rhombic geometry to deliver consistent cutting performance when machining hardened steels. The coated CBN composition is engineered for extreme wear resistance, which reduces flank wear and extends tool life under high contact stresses. As a result, process windows can be confidently widened, improving cycle times and lowering per-part tool costs. The design emphasises reliable chip control and repeatable results, making it suitable for serial production where stability and economy matter.

Stable geometry that supports precision and surface quality

Featuring a rhombic 80° shape and a 0° negative rake, the insert provides high cutting edge stability and reduced vibration during heavy interrupted cuts. The 0.4 mm corner radius helps achieve a consistent surface finish without sacrificing edge strength, particularly on hard workpieces. For operators and process planners, this means fewer reworks and less downstream finishing. The component geometry also supports predictable engagement angles, simplifying tool path strategies and fixture design for turning centres and CNC lathes.

Application scope, material compatibility and handling

This grade is tailored for the ISO group H — hardened steels — and is appropriate for hard turning and finish turning of quenched or induction-hardened components. The product belongs to the Walter CBN / hard material series and is optimised for high wear conditions where conventional carbide would fail prematurely. Inserts are supplied in the CNGA120404TM-2 designation with the WBH10C grade, enabling straightforward tool selection and reliable interchangeability in production environments.

FAQ

What materials is this insert designed for?
The CNGA120404TM-2 WBH10C insert is designed primarily for hardened steels (ISO group H), where its coated CBN grade provides superior wear resistance.

How does the 0° negative rake affect cutting performance?
A 0° negative rake increases edge stability and resistance to chipping under heavy loads, enhancing process security during interrupted or deep cuts.

What surface quality can be expected with a 0.4 mm corner radius?
The 0.4 mm corner radius balances edge strength and finish quality, delivering consistent surface integrity with reduced burr formation on hard materials.

Can this insert be used for finish turning as well as roughing?
Yes, the combination of coated CBN and the rhombic 80° geometry allows effective use in both heavy-duty roughing and precise finishing applications on hardened components.

Is the CNGA120404TM-2 WBH10C compatible with standard insert holders?
The CNGA designation follows common insert standards; compatibility should be checked against the specific holder geometry and clamping system in use
