Product Overview
The Kyocera VNMG160402PP is a premium indexable turning insert featuring the CA025P grade with a Precision Positive chipbreaker. Engineered for medium turning, this 35° rhombus (diamond) insert delivers exceptional performance in steel machining applications. The CA025P grade combines a tough cemented carbide substrate with a multi-layer CVD coating (TiCN/Al₂O₃/TiN) to provide outstanding wear resistance, thermal stability, and extended tool life.

Operating Guidelines
- Coolant: High-pressure coolant recommended for chip evacuation and heat dissipation. Minimum 5% emulsion or synthetic coolant.
- Tool Overhang: Keep tool overhang to minimum (≤ 1.5× tool diameter) to prevent vibration and chatter.
- Edge Preparation: Do not re-sharpen CVD-coated inserts. Replace when flank wear exceeds 0.3 mm or when chipping is observed.
- Entry/Exit: Use ramp entry for interrupted cuts. Avoid direct plunge into shoulders.
- Speed Adjustment: Reduce Vc by 20–30% for interrupted cuts or work-hardened materials.
- Feed Rate: Maintain consistent feed to ensure proper chipbreaker function and chip curling.
