Kyocera TPMT110308HQ CA125P – Turning Insert (10 pcs Finishing to Medium, HQ Chipbreaker)
The Kyocera TPMT110308HQ CA125P is a positive-type triangular turning insert designed for finishing to medium cutting operations in steel. Supplied in a pack of 10 inserts, it features the advanced CA125P CVD-coated carbide grade, developed to provide excellent wear resistance, toughness, and stability under both continuous and interrupted cutting. The innovative coating structure combines a uniform alumina film with a TiCN layer, ensuring superior crater and flank wear resistance. Paired with the HQ chipbreaker, this insert delivers smooth chip control, low cutting resistance, and consistent tool life across diverse machining conditions.
Key Features & Benefits
- CA125P Grade: Next-generation CVD-coated carbide engineered for steel turning with outstanding wear resistance and fracture toughness.
- Advanced Coating Structure: Uniform alumina layer enhances heat and wear resistance, while TiCN improves edge toughness and durability.
- HQ Chipbreaker: Provides stable chip evacuation and reduced cutting forces during finishing to medium-depth cutting.
- Extended Tool Life: Up to 2× longer service life compared to conventional competitor grades (internal Kyocera evaluation).
- Stable Machining: Delivers consistent surface finish and predictable wear behavior under both wet and dry cutting conditions.
- Pack Quantity: Supplied as a pack of 10 inserts for convenient and cost-effective tool management.
Applications
- Finishing and medium machining of carbon and alloy steels (e.g., S45C, SCM435, SCM440).
- Ideal for automotive, industrial, and general engineering components such as shafts, bolts, and gears.
- Recommended cutting conditions: Vc = 190–300 m/min, ap = 0.3–2.0 mm, f = 0.1–0.4 mm/rev (wet cutting).
