CCGW09T304TM-2 WBH30 — CBN turning insert for hard‑material machining (Walter Tools)

CCGW09T304TM-2 WBH30 is a CBN indexable turning insert engineered for tough, hardened‑steel and hard‑material turning tasks, delivering stable cutting performance in demanding production environments

• CBN grade WBH30 for hard materials
• Rhombic 80° geometry for versatile turning
• 7° relief angle for robust cutting action
• 0.4 mm corner radius for controlled edge strength

High wear resistance for hard turning stability

The insert is made in a CBN cutting grade (WBH30) developed for high‑wear situations encountered during hard turning of hardened steels. CBN (cubic boron nitride) is a superabrasive that maintains a sharp cutting edge under elevated temperatures and pressures, which reduces flank wear and extends service intervals. As a result, production runs benefit from fewer tool changes, more consistent surface finishes and reduced scrap rates — a clear advantage for processes where repeatability and uptime are decisive. The design supports predictable edge behaviour, improving process control when machining pre‑hardened and heat‑treated components.

Geometry engineered for chip control and stability

The rhombic 80° insert shape and 7° relief angle combine to provide a positive yet sturdy cutting geometry that resists chipping while enabling access to diverse turning positions. A 0.4 mm corner radius balances edge strength with the capacity to produce acceptable surface roughness on finish passes. The plate thickness T3 and dual chipbreaker configuration enhance rigidity and chip evacuation, lowering vibration and thermal fluctuation at the cutting zone. For operators and process engineers, this geometry translates into more stable cutting forces and improved dimensional consistency across batch production.

Application guidance and economic impact

Primarily intended for hard machining applications, the grade is suitable for components made from hardened or pre‑hardened steels. When used in appropriately configured holders and with stable machine setups, the insert reduces unplanned downtime and contributes to a lower cost per part through longer life and consistent results. Walter Tools’ CBN series is designed to offer process security and predictable performance, supporting higher machine utilisation and fewer interventions by operators. For newcomers to CBN machining, the material benefits justify initial parameter refinement: conservative feeds and proper coolant strategy where applicable lead to rapid optimisation and measurable productivity gains.
