10pc Kyocera TNMG220412PS CA525 – Turning Insert (Medium to Roughing, PS Chipbreaker)

Kyocera TNMG220412PS CA525 – Turning Insert (10 pcs Medium to Roughing, PS Chipbreaker)

The Kyocera TNMG220412PS CA525 is a high-performance negative-type triangular turning insert engineered for medium to roughing operations in steel machining. It features Kyocera’s proven CA525 CVD-coated carbide grade, combining excellent wear resistance and toughness for stable performance in a wide range of cutting conditions. The robust PS chipbreaker geometry provides consistent chip control, low cutting resistance, and reliable edge stability even during heavy cuts and interrupted machining.

Key Features & Benefits

• CA525 Grade: Tough and wear-resistant CVD-coated carbide grade optimized for steel turning; offers a balance of thermal stability and durability.
• PS Chipbreaker: Stepped geometry ensures efficient chip evacuation and superior cutting stability in medium-to-heavy cutting conditions.
• Stable Edge Strength: Reinforced cutting edge minimizes chipping and fracture during roughing and interrupted operations.
• Long Tool Life: Excellent resistance to flank and crater wear extends tool service intervals, enhancing productivity.
• Versatile Machining: Performs reliably in both continuous and interrupted cutting on carbon and alloy steels.

Applications

• Medium to rough turning of carbon and alloy steels (e.g., S45C, SCM435, SCM440).
• Ideal for automotive and general engineering components requiring stable cutting and high removal rates.
• Recommended cutting conditions: Vc = 150–280 m/min, ap = 1.0–5.0 mm, f = 0.2–0.6 mm/rev (wet cutting).
