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

Chipbreaker Profile

Precision Chipbreaker (PH) – Optimized for low-feed finishing operations with minimal cutting forces and superior surface finish

  • Chip Control: Optimized groove geometry ensures reliable chip breaking across feed rates 0.1–0.4 mm/rev
  • Edge Preparation: Honing (T-land) for improved edge stability and reduced burr formation
  • Surface Finish: Polished rake face minimizes built-up edge and improves surface quality
  • Coolant Compatibility: Suitable for both wet and dry machining environments

Cast Iron (GG25)150–2200.15–0.401.5–5.0Dry 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
