Kyocera TNMG220404PS CA025P – Turning Insert (10 pcs Medium to Roughing, PS Chipbreaker)
The Kyocera TNMG220404PS CA025P is a negative-type triangular turning insert designed for medium to roughing steel machining. It incorporates Kyocera’s state-of-the-art CA025P CVD-coated carbide grade, engineered with a thick alumina layer for exceptional wear resistance, improved adhesion resistance, and outstanding fracture toughness. The PS chipbreaker geometry provides efficient chip evacuation, low cutting resistance, and stable edge performance, delivering long tool life and consistent results across a wide range of cutting conditions.
Key Features & Benefits
- CA025P Grade: Next-generation CVD-coated carbide for steel turning; offers enhanced thermal stability and superior wear control.
- Advanced Coating Structure: Thicker alumina film improves heat resistance and oxidation protection at elevated cutting temperatures.
- PS Chipbreaker: Designed for medium-to-roughing operations, ensuring stable chip flow and strong edge integrity.
- Enhanced Fracture Resistance: High-toughness substrate resists chipping and deformation in interrupted or heavy cutting.
- Extended Tool Life: Internal evaluations show up to 1.5–2× longer life compared to conventional P25 grades in steel machining.
Applications
- Medium to rough turning of carbon and alloy steels (e.g., S45C, SCM415, SCM435, SCM440).
