The Vortex CNGA120408-CBN30 turning insert is a non-regrindable, single-edge solution designed for machining hardened steels. Its CNGA geometry delivers reliable, consistent performance in tough applications.

For best results, pair with double clamp turning tools or boring bars to minimize vibration and extend tool life.

• Non-regrindable single-edge design: Eliminates the need for regrinding, reducing downtime and simplifying inventory while delivering dependable performance on hardened steels.
• CBN edge for hardened steels: Superior wear resistance provides longer edge life and fewer insert changes in demanding, high-hardness materials.
• Optimized for vibration control: Designed to work with double clamp turning tools or boring bars to minimize chatter and extend tool life, improving surface finish and process reliability.

Using the CNGA120408-CBN30 translates to more consistent results on hardened steel workpieces, fewer interruptions for tool changes, and a smoother, more predictable machining process. The combination of non-regrindable construction, CBN material, and compatibility with stable clamping setups gives you reliable performance across jobs, helping you meet tight tolerances and finish requirements with confidence.
