The Vortex CNGA120408-CBN20 turning insert is a non-regrindable, single-edge tool designed specifically for turning hardened steels. Built to deliver consistent performance in demanding applications, it helps shops and technicians achieve reliable material removal without the need for grinding inserts again and again.

Designed for ease of use on the shop floor, this CNGA insert shines when paired with the right tooling. For best results, use double-clamp turning tools or boring bars to minimize vibration and maximize tool life, helping you maintain stable cuts and predictable finishes across batches.

• Non-regrindable, single-edge design: Eliminates the need for regrinding and ensures consistent performance from replacement inserts, reducing downtime and preserving cutting efficiency.
• Optimized for hardened steels: Engineered for strong wear resistance and stable chip control when machining high-hardness materials, delivering reliable performance batch after batch.
• Best results with double-clamp tools or boring bars: Reduces vibration and chatter, extending insert life and improving surface finish during heavy cuts.

With the Vortex CNGA120408-CBN20, you gain a reliable solution for hardened-steel turning that reduces downtime, improves surface consistency, and extends tool life. The single-edge, non-regrindable design simplifies stocking and replacement, while its compatibility with double-clamp turning tools and boring bars delivers stable cuts and predictable results across production runs.
