Kyocera SNMG120408HQ CA125P – Turning Insert (10 pcs Finishing to Medium, HQ Chipbreaker)
The Kyocera SNMG120408HQ CA125P is a negative-type square turning insert designed for finishing to medium operations in steel machining. It features Kyocera’s advanced CA125P CVD-coated carbide grade, engineered for excellent wear resistance, fracture toughness, and edge stability. The HQ chipbreaker ensures smooth chip control, reduced cutting force, and consistent surface quality across a wide range of cutting parameters, making it ideal for both continuous and light interrupted cutting applications.
Key Features & Benefits
- CA125P Grade: CVD-coated carbide optimized for general steel machining with superior wear and chipping resistance.
- Advanced Coating Structure: Uniform alumina and TiCN layers improve heat resistance and coating adhesion for extended tool life.
- HQ Chipbreaker: Provides stable chip formation and excellent surface finish during finishing and medium-depth cutting.
- High Edge Strength: Reinforced cutting edge design ensures reliability in both continuous and slightly interrupted operations.
- Extended Tool Life: Up to 2× longer life than conventional P25 grades in internal Kyocera evaluations.
Applications
- Finishing to medium turning of carbon steels and alloy steels (e.g., S45C, SCM415, SCM440).
