4. Grade Details — Key Grade Characteristics
CA515 is CVD-coated carbide grade optimized for steel and stainless steel machining. Features a thick alumina (Al₂O₃) coating layer for excellent heat resistance and a titanium carbonitride (TiCN) base layer for superior adhesion and wear resistance.
- Substrate: Fine-grained tungsten carbide (WC-Co) with 10% cobalt binder for optimal toughness
- Coating: Multi-layer CVD coating — TiCN base + Al₂O₃ middle + TiN top layer
- Coating Thickness: 8-12 μm total coating thickness
- Hardness: 1,520 HV (Vickers)
- Transverse Rupture Strength: 2,800 MPa
- Operating Temperature: Up to 1,000°C continuous cutting
- Color Code: Gold-TiN top layer for easy wear identification
5. Grade Comparison Matrix

6. Chipbreaker Profile
The HQ chipbreaker geometry features a precisely engineered groove and land configuration designed for high-precision finishing:
- Land Width: 0.15-0.25 mm (optimized for minimal burr formation)
- Groove Depth: 0.08-0.12 mm (ensures controlled chip curl)
- Backwall Angle: 25°-30° (promotes chip evacuation)
- Frontwall Angle: 12°-15° (reduces cutting force and heat generation)
- Chip Control Range: Effective for feed rates of 0.05-0.15 mm/rev

10. Operating Guidelines
- Tool Setup: Ensure insert seat is clean and undamaged before mounting. Use calibrated torque wrench for clamping screw (recommended 2.5-3.5 N·m).
- Run-In Period: For new installations, reduce cutting speed by 20% for the first 10 minutes to allow coating stabilization.
- Chip Evacuation: Ensure adequate coolant flow (minimum 6 bar pressure) to prevent chip recutting and built-up edge formation.
- Insert Indexing: Rotate insert to fresh cutting edge when flank wear (VB) reaches 0.3 mm or when surface finish deteriorates visibly.
- Storage: Store in original packaging in a dry environment (humidity <60%) to prevent coating oxidation.
- Safety: Always wear appropriate PPE when handling sharp carbide inserts. Dispose of worn inserts according to local metal waste regulations.
