Kyocera TCMT16T304HQ CA525 – Turning Insert 

The Kyocera TCMT16T304HQ CA525 is a positive-type triangular turning insert designed for finishing to medium machining in steel. Supplied in a pack of 10 inserts, it features the proven CA525 CVD-coated carbide grade, engineered to deliver an ideal balance of wear resistance and toughness for stable and long-lasting performance. The HQ chipbreaker provides excellent chip evacuation, reduced cutting force, and smooth surface finishes, ensuring reliability during both continuous and light interrupted cutting operations.

Key Features & Benefits

• CA525 Grade: Robust CVD-coated carbide optimized for steel turning, offering excellent wear resistance and fracture toughness.
• HQ Chipbreaker: Provides stable chip control and low cutting resistance during finishing and medium-depth operations.
• Reliable Edge Strength: Maintains consistent sharpness while resisting chipping under variable load conditions.
• Stable Tool Life: Predictable wear and extended longevity even during light interrupted cutting.
• Pack Quantity: Supplied as a pack of 10 inserts for convenience and efficiency in production environments.

Applications

• Ideal for general turning of carbon and alloy steels (e.g., S45C, SCM435, SCM440).
• Commonly used in automotive and industrial parts such as shafts, housings, and flanges.
• Recommended cutting conditions: Vc = 150–250 m/min, ap = 0.3–1.5 mm, f = 0.1–0.3 mm/rev (wet cutting).
