The Vortex DNGA150612-CBN30 turning insert is a non-regrindable, single-edge cutting insert designed for machining hardened steels. CBN inserts can eliminate the need for additional grinding inserts; for best results with CBN turning inserts please use double clamp turning tools or boring bars to minimize vibration and extend tool life.

• Non-regrindable, single-edge design: Maintains consistent geometry and reliable cuts without the need for regrinding, reducing maintenance downtime and material waste.
• CBN technology for hardened steels: Delivers longer tool life and fewer insert changes when working with tough alloys, helping you maintain production momentum.
• Optimized for stable cutting with proper tooling: When paired with double clamp turning tools or boring bars, vibration is minimized, improving surface finish and extending overall tool life.

Using this insert in hardened-steel turning tasks helps you achieve repeatable, high-quality results while reducing downtime and tooling costs. Its durable CBN edge stands up to demanding cuts, supporting tighter tolerances and consistent finishes across multiple parts.
