Kyocera TPMR160304 CA125P – Turning Insert (10 pcs Positive Type, Steel Machining)
The Kyocera TPMR160304 CA125P is a positive-type triangular turning insert designed for steel machining. It utilizes the advanced CA125P CVD-coated carbide grade, which provides superior wear resistance, fracture toughness, and stable performance under both continuous and interrupted cutting conditions. The unique multi-layer coating structure combines a highly uniform alumina layer, TiCN layer, and a proprietary carbide substrate, ensuring longer tool life and improved resistance to crater wear and flank wear.
Key Features & Benefits
- CA125P Grade: First recommendation for steel machining with excellent balance of wear resistance and toughness.
- Advanced Coating: Uniform alumina film reduces crater wear; golden surface layer makes edge defects easy to identify.
- Durability: Internal evaluations show up to 1.5× greater wear resistance and 1.3× higher fracture resistance compared to competitors.
- Stable Edge Condition: Improved resistance to chipping and plastic deformation, extending reliable tool life.
Applications
- General steel machining, including automotive components, shafts, gears, and industrial parts.
- Effective for continuous and interrupted cutting at medium-to-high cutting speeds.
- Catalog examples: Vc = 250–300 m/min, ap ≈ 1.0–1.5 mm, f = 0.3–0.4 mm/rev (materials like S45C, SCM435, SUJ2).
