High Wear Resistant Solid CBN Turning Inserts for Hardened Steel Machining & Replace Grinding

Solid CBN inserts solve the common pain point of short tool life when machining HRC50+ materials. They hold surface finish stable even as production cycles stack up, allowing you to run more conservative parameters safely or push aggressive feeds for faster throughput. By cutting down the frequency of tooling changes per operation, CBN inserts save valuable setup time and eliminate bottlenecks caused by frequent tool swaps and grinding follow-up work.

• Extended tool life: Super-hard CBN grade resists edge wear far beyond conventional carbide when cutting hardened steel and cast iron.
• Stable surface finish: Consistent Ra values are maintained from the first part to the last part of the batch, keeping dimensional drift under control.
• Reduced coolant reliance: Unlike most carbide turning inserts, CBN inserts reduce dependence on emulsion or mist coolant, lowering mess and ongoing coolant disposal costs.
• Improved chip evacuation: Design helps stop chips from re-cutting the finished surface, protecting part quality.
• Drop-in compatibility: Fits standard CNGA, WNMG, and SNGA tool holders for easy replacement with no machine modifications.
• Setup flexibility: Offers far more adaptability than specialty coated carbide grades across prototype batches and high-volume production.
• Grinding replacement: Turns hard-machining headaches into repeatable, profitable runs when grinding cycles become too costly.
