Product Overview
The Kyocera TNMG160404PS CA525 TAC06255 is a precision-engineered indexable carbide insert designed for semi-finishing insert applications. Manufactured in Japan under strict ISO 9001 quality standards, this insert delivers exceptional surface finish, dimensional accuracy, and extended tool life on CNC turning centers and milling machines.
The optimized chipbreaker geometry minimizes cutting forces and enhances chip control, ensuring consistent and repeatable results across high-volume production runs. The CA525 grade features a multi-layer CVD coating that provides excellent wear resistance and thermal stability during demanding machining operations.

Application Map by Operation
| Operation Type | Suitability | Depth of Cut (ap) | Feed Rate (fn) |
|---|---|---|---|
| External Turning | ★★★★★ Excellent | 0.5 - 4.0 mm | 0.10 - 0.40 mm/rev |
| Internal Turning (Boring) | ★★★★☆ Very Good | 0.5 - 3.0 mm | 0.10 - 0.30 mm/rev |
| Face Turning | ★★★★★ Excellent | 0.5 - 3.5 mm | 0.12 - 0.35 mm/rev |

Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (C45) | 150-250 | 0.15-0.40 | 0.5-3.0 |
| Stainless Steel (304) | 100-180 | 0.12-0.30 | 0.5-2.5 |
| Cast Iron (GG25) | 120-200 | 0.15-0.35 | 0.5-3.0 |
| Alloy Steel (4140) | 120-200 | 0.15-0.35 | 0.5-3.0 |
Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece condition, and coolant application. Use lower values for interrupted cuts or unstable setups.
Operating Guidelines
- Coolant: High-pressure coolant (70+ bar) recommended for stainless steel and deep cavities
- Entry Angle: Maintain 91-95° tool entering angle for optimal chip control
- Nose Radius: Larger radius (0.4mm) improves surface finish but increases radial forces
- Tool Overhang: Minimize overhang to reduce vibration; use damped toolholders for L/D > 4
- Insert Seat: Ensure clean seat and proper clamping torque (3.5-4.5 Nm)
- Edge Preparation: Do not touch cutting edge with bare hands; use proper insert changing tools
