CCGW060208TM-2 WBH20C indexable insert — CBN grade, Rhombus 80°, 7° clearance — Walter Tools

The CCGW060208TM-2 WBH20C is an indexable insert designed for hard machining and finishing operations on hardened steels; it combines a coated CBN cutting grade with a rhombic geometry for stable cutting and reliable surface quality.

• Coated CBN grade WBH20C
• Suitable for hardened steels (ISO H)
• Rhombus 80° geometry for versatile turning
• 0.8 mm corner radius for fine finishing

High-performance cutting for hardened materials

The insert is built around a coated CBN cutting material (grade WBH20C), which is specifically engineered for hardened steels and other highly abrasive workpieces. This choice of material delivers superior wear resistance, meaning fewer insert changes and more consistent cycle times in production. In practical terms, the robust cutting grade reduces flank wear and preserves the edge integrity during interrupted cuts or high contact pressures, helping to maintain tolerances and surface finish across longer component runs.

Geometry and clearance tuned for reliable turning

The Rhombus 80° geometry with a 7° clearance provides a balance between cutting strength and access to the cutting zone, making the insert suitable for both roughing and finishing passes where hardness and rigidity are key. The 0.8 mm corner radius supports improved surface generation on finishing passes while limiting stress concentration at the edge. The insert’s two-chipbreaker configuration further aids chip control during hard turning, reducing the risk of built-up edge and improving process stability in demanding industrial applications.

System integration and application scope

Belonging to the Walter CBN / hard material series, the insert is designated for hard machining tasks according to ISO group H, and it is suitable for pre-hardened and hardened workpieces where standard carbide solutions reach their limits. The standard designation and size allow straightforward integration into compatible toolholders and cartridges used in CNC turning centres. For procurement and process planning, the stable performance of the cutting grade can contribute to predictable tool-change intervals and consistent part quality in serial production.

FAQ

What materials is this insert suitable for?
The CCGW060208TM-2 WBH20C is intended primarily for hardened steels (ISO group H) and for applications requiring a coated CBN grade to cope with high wear and heat during hard turning.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius on the insert helps to produce a finer surface on finishing passes by distributing cutting forces and reducing the likelihood of edge chipping, improving the consistency of the turned component.

Can this insert be used for roughing as well as finishing?
Yes. The combination of Rhombus 80° geometry and a wear-resistant WBH20C grade allows the insert to perform both roughing and finishing in hard machining, provided cutting parameters are adapted to the operation.

What is the function of the chipbreaker designation '2'?
The chipbreaker configuration marked as 2 is designed to assist chip control during interrupted or continuous cuts in hard materials, promoting safe chip evacuation and reducing risk of built-up edge.

Is the insert compatible with standard CCGW toolholders?
The insert follows the common CCGW designation, and the CCGW060208TM-2 WBH20C can be mounted in holders that accept this insert geometry and size; holder selection should match the intended cutting application and machine rigidity.
