Grade Details – Key Grade Characteristics
CA4515 is a high-performance CVD-coated carbide grade from Kyocera, engineered specifically for turning operations in steel and stainless steel applications. The multi-layer coating architecture combines a tough substrate with wear-resistant outer layers, delivering exceptional balance between flank wear resistance and fracture toughness.
- Coating Technology: Multi-layer CVD (Chemical Vapor Deposition) – TiCN + Al₂O₃ + TiN
- Substrate: Tough WC-Co carbide with optimized grain structure
- Color Code: Gold/Yellow top layer for easy identification
- Operating Range: Medium to high cutting speeds (150–350 m/min)
- Temp. Resistance: Up to 1,000°C in the cutting zone

Recommended Cutting Conditions
Starting parameters for stable machining. Adjust based on machine rigidity and setup:
| Material | Vc (m/min) | fn (mm/rev) | ap (mm) | Coolant |
|---|---|---|---|---|
| Low-Carbon Steel | 200–300 | 0.15–0.35 | 1.0–4.0 | Wet / Dry |
| Medium-Carbon Steel | 180–260 | 0.12–0.30 | 1.0–3.5 | Wet Recommended |
| Stainless Steel 304 | 120–180 | 0.10–0.25 | 0.8–2.5 | Wet Mandatory |
| Stainless Steel 316 | 100–150 | 0.10–0.20 | 0.5–2.0 | Wet Mandatory |
| Cast Iron (GG25) | 150–220 | 0.15–0.40 | 1.5–5.0 | Dry Preferred |
Operating Guidelines
- Speed Selection: Start at the lower end of the recommended Vc range and increase gradually while monitoring tool wear
- Feed Rate: For finishing operations, use the lowest feed rate compatible with productivity targets to maximize surface finish
- Depth of Cut: Maintain consistent ap where possible; avoid intermittent cutting below 0.2 mm to prevent rubbing
- Coolant: Use high-pressure coolant (70+ bar) for chip evacuation in deep cavities and blind holes
- Tool Life Check: Monitor flank wear (VB). Recommended limit: 0.3 mm for roughing, 0.15 mm for finishing
- Edge Preparation: Do not re-sharpen coated inserts. Replace when wear reaches limit or chipping occurs
- Storage: Keep inserts in original packaging away from moisture and corrosive environments
