Grade Details — Key Grade Characteristics
The CA025P grade represents Kyocera's next-generation CVD coating technology, specifically developed for steel machining (ISO P-group materials). It combines a thickened alumina (Al₂O₃) layer with an optimized cemented carbide substrate to deliver industry-leading performance.
| Property | Specification |
|---|---|
| Coating Technology | CVD Coated Carbide (TiCN + Al₂O₃ + TiN) |
| Insert Color | Gold |
| ISO Application Group | P (Steel) |
| Substrate Hardness | HV 1,400 |
| Transverse Rupture Strength | 13.5 GPa |
| Fracture Toughness | 2.80 MPa·m¹/² |
- Thickened alumina layer (2x conventional) for superior thermal resistance
- New substrate with high stability for excellent chipping resistance
- Specialized post-coating process prevents material adhesion
- Improved plastic deformation resistance at high temperatures
- Extended tool life across wide cutting conditions
Grade Comparison Matrix
| Grade | Coating | Wear Resistance | Fracture Resistance | Best For |

Recommended Cutting Conditions
Values shown are starting recommendations. Adjust based on machine rigidity, workpiece condition, and desired tool life.
| Workpiece Material | Condition | Vc (m/min) | ap (mm) | f (mm/rev) |
|---|---|---|---|---|
| Low Carbon Steel (≤150 HB) | Continuous | 150 – 320 | 1.0 – 4.0 | 0.20 – 0.50 |
| Interrupted | 120 – 260 | 1.0 – 3.0 | 0.15 – 0.40 | |
| Medium Carbon Steel (150-250 HB) | Continuous | 120 – 280 | 1.0 – 4.0 | 0.20 – 0.50 |
| Interrupted | 100 – 220 | 1.0 – 3.0 | 0.15 – 0.40 | |
| Alloy Steel (250-300 HB) | Continuous | 100 – 240 | 1.0 – 3.5 | 0.15 – 0.45 |
| Interrupted | 80 – 190 | 1.0 – 2.5 | 0.12 – 0.35 |
Operating Guidelines
- Coolant: Wet cutting is strongly recommended for optimal tool life and surface finish. Use water-soluble coolant at 5-8% concentration.
- Edge Preparation: Do not re-sharpen or re-coat inserts. Use only factory-sharp edges for best performance.
- Insert Seating: Ensure clean, undamaged seat in toolholder. Torque clamping screw to manufacturer specification (typically 3.5-4.5 N·m).
- Index Frequency: Index insert when flank wear reaches 0.3 mm or when surface finish degrades noticeably.
- Storage: Store in original packaging away from moisture and corrosive environments. Temperature: 5-35°C, Humidity: ≤65% RH.
- Workpiece Preparation: Remove scale and oxide layers before machining. Ensure adequate rigidity of workpiece and machine setup.
- Speed Adjustment: Reduce cutting speed by 15-20% for cast surfaces, welds, or heavily scaled material.
Toolholder Compatibility
This CNMG090404HQ insert is designed for use with the following Kyocera toolholder series:
| Toolholder Series | Style | Approach Angle | Typical Use |
|---|---|---|---|
| MCMNN | External | 95° | General external turning |
| MCMNR/L | External | 95° | Right/Left hand external turning |
| MCMWN | External | 95° | High stability external turning |
| DCLNR/L | External | 93° | Profiling and facing operations |
Ensure toolholder seat angle matches the insert relief angle (0°). Use precision-ground seats for best results.
