CCGW09T308TM-2 WBH20C – Turning insert for hard machining | Walter Tools

The CCGW09T308TM-2 WBH20C is a CBN turning insert designed for hard machining of hardened steels, delivering high wear resistance and process stability in demanding finishing and light roughing applications

• CBN grade for extreme wear resistance
• Designed for hardened steels (H)
• Rhombic 80° form for secure seating
• 0.8 mm corner radius for robust edge

Reliable cutting performance for hardened materials

The insert is manufactured in a CBN class cutting material that is specifically engineered for machining hardened steels and pre-hardened workpieces. This composition gives a significantly higher wear resistance compared with conventional carbide grades, which translates directly into longer tool life and fewer indexings. In practical terms, the hardened-cutting capability reduces unscheduled tool changes and supports a predictable production rhythm, making the grade particularly suitable where repeatable results and minimal downtime are required.

Geometry tuned for stability and surface quality

The Rhombic 80° form combined with a 7° clearance and a 0.8 mm corner radius creates a secure seat in the toolholder and a resilient cutting edge under elevated cutting forces. The defined geometry helps to maintain a stable chip flow and reduces vibration during the cut, which improves surface finish and protects the cutting edge. The T3 plate thickness contributes to mechanical rigidity, ensuring that the insert withstands the stresses of hard turning without premature deformation.

Application benefits: productivity and process security

Because the grade is optimised for hard materials, the insert supports higher material removal rates in applications where abrasive wear would quickly blunt other grades. The design and grade combination promote consistent cutting conditions, which enhances productivity and process security in serial production. For workshop planners and process engineers, this means more predictable tool life, reduced inventory for spare inserts and an easier route to stable cycle times on challenging components.

Practical handling and integration into existing tooling

The insert’s ISO designation and standard form allow straightforward mounting in compatible turning toolholders, simplifying tool management in mixed fleets. The integrated chipbreaker supports controlled chip formation for common hard-turning conditions, while the stable edge geometry reduces the need for frequent operator adjustments. For customers requiring further clarification on holder compatibility or cutting-data recommendations, technical support and application advice are available to assist with selection and process set-up.
