10pc Kyocera TNMG220408PS CA025P – Turning Insert (Medium to Roughing, PS Chipbreaker)

Kyocera TNMG220408PS CA025P – Turning Insert (10 pcs Medium to Roughing, PS Chipbreaker)

The Kyocera TNMG220408PS CA025P is a negative-type triangular turning insert designed for medium to roughing steel machining. It features Kyocera’s advanced CA025P CVD-coated carbide grade, developed with a next-generation coating structure for superior wear resistance, improved adhesion resistance, and excellent fracture toughness. The PS chipbreaker provides stable chip control, smooth cutting, and reliable edge strength, making this insert ideal for continuous and light-interrupted operations in general steel turning.

Key Features & Benefits

• CA025P Grade: Next-generation CVD-coated carbide for steel with twice the alumina thickness of conventional coatings, offering higher heat resistance and longer tool life.
• Improved Fracture Resistance: Advanced substrate formulation enhances strength under high temperature and heavy-load cutting.
• Superior Adhesion Resistance: Optimized coating adhesion prevents flaking and ensures smooth, stable wear patterns.
• PS Chipbreaker: Designed for medium to roughing applications, ensuring excellent chip evacuation and consistent cutting stability.
• Extended Tool Life: Internal tests show up to 40–50% longer tool life versus conventional P25 grades during steel turning.

Applications

• Medium to rough turning of carbon and alloy steels (e.g., S45C, SCM435, SCM440).
• Suitable for continuous and interrupted cutting conditions with high reliability.
• Recommended cutting conditions: Vc = 150–280 m/min, ap = 1.0–5.0 mm, f = 0.2–0.6 mm/rev (wet cutting).
