Description
Meet the Carmex Grooving Insert with snap ring retention and rounded edges—designed for machinists who demand stable, precise grooving and long tool life. The BXC-coated insert combines secure seating, smooth cutting edges, and lubricity to tackle high-speed grooving with confidence.

- Code / Size: 16IR/ELR0.50BXC
- Retention System: Snap Ring design securely seats the insert, minimizing movement during cutting
- Edge Geometry: Rounded cutting edges enable smooth groove formation and aid in chip evacuation
- BXC Coating: Advanced coating for improved wear resistance, heat tolerance, and lubricity at high speeds
- Chip Control: Optimized geometry and coating deliver superior chip control and cleaner grooves
- Applications: Ideal for grooving operations in turning setups, delivering consistent groove dimensions and stable performance
This insert translates secure retention and thoughtful geometry into tangible benefits: tighter groove tolerances, better surface finishes, and longer tool life. The snap ring minimizes insert movement, helping maintain accurate groove depth and width across multiple passes. Rounded edges reduce chip buildup and promote efficient evacuation, reducing downtime caused by chip-related interruptions. The BXC coating lowers friction and withstands heat, enabling higher cutting speeds without sacrificing accuracy. For high-volume grooving work, this combination provides reliable performance, better cycle times, and cost-effective tooling life.
