Grade Details – Key Grade Characteristics
The CA525 grade is a CVD-coated carbide substrate featuring a multi-layer coating architecture optimized for steel and stainless steel machining. The substrate combines high toughness with excellent wear resistance, while the TiCN/Al₂O₃/TiN coating layers provide thermal protection and crater wear resistance.
| Characteristic | Specification |
|---|---|
| Coating Type | CVD Multi-Layer (TiCN + Al₂O₃ + TiN) |
| Substrate | WC-Co Carbide (Medium Grain) |
| Hardness | ~1,500 HV |
| Transverse Rupture Strength | ~2,800 MPa |
| Color Code | Gold/Yellow (TiN Top Layer) |
Grade Comparison Matrix
Select the optimal grade for your application by comparing Kyocera's popular CVD-coated offerings:
| Grade | Coating | Primary Use | Speed Capability |
|---|---|---|---|
| CA525 | CVD TiCN/Al₂O₃/TiN | Steel, Stainless Steel | Medium–High |
| CA530 | CVD TiCN/Al₂O₃ | General Steel | Medium |

| CA6515 | PVD TiAlN | Stainless, Exotic | Medium |
Chipbreaker Profile
The Heavy-Duty Chipbreaker chipbreaker on the DCMT11T308XQ is specifically engineered for heavy-duty roughing. Key geometric features include:
- Front Rake Angle: Optimized positive geometry for reduced cutting forces and improved chip flow
- Chip Groove Depth: Calibrated for stable chip curling and controlled chip evacuation
- Land Width: Narrow honing for sharp cutting edge and minimal burr formation
- Edge Preparation: T-land or slight hone depending on chipbreaker variant for edge strength
This chipbreaker profile ensures reliable chip control across the recommended feed and depth-of-cut ranges, reducing the risk of chip jamming and improving surface integrity.
Recommended Applications & Workpiece Materials
The Kyocera DCMT11T308XQ with CA525 grade is optimized for the following workpiece materials and scenarios:
- Carbon & Alloy Steels: Excellent for continuous and light interrupted cuts in AISI 1045, 4140, 4340
- Stainless Steels: Ideal for austenitic grades (304, 316) and duplex stainless steels
- Tool Steels: Suitable for pre-hardened tool steels up to 45 HRC
- Cast Irons: Effective on gray cast iron (GG25) and ductile iron (GGG40)
- General Engineering: Perfect for shafts, flanges, valves, and pump components
Application Map by Operation
Operational suitability and recommended parameter adjustments:
| Operation | Suitability | Recommended Conditions |
|---|---|---|
| External Turning | ✓ Excellent | vc = 100–200 m/min, f = 0.15–0.60 mm/rev |
| Internal Turning (Boring) | ✓ Excellent | Reduce vc by 15–20% |
| Facing | ✓ Good | Use constant surface speed |
| Profiling | ✓ Good | Nose radius dependent |
| Grooving / Cut-off | ✗ Not Recommended | Use dedicated grooving inserts |
Recommended Cutting Conditions
Starting parameters for stable machining. Adjust based on machine rigidity and workpiece condition:
| Workpiece Material | Cutting Speed vc (m/min) | Feed f (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (≤ 0.45% C) | 100–200 | 0.15–0.60 | 1.00–6.00 |
| Alloy Steel (≤ 40 HRC) | 100–200 | 0.15–0.60 | 1.00–6.00 |
| Stainless Steel (Austenitic) | 100–180 | 0.10–0.35 | 0.50–3.00 |
| Cast Iron (Gray / Ductile) | 120–200 | 0.10–0.40 | 1.00–4.00 |
| Tool Steel (≤ 50 HRC) | 80–140 | 0.08–0.25 | 0.50–2.50 |
Operating Guidelines
- Always verify insert seat and clamping mechanism before operation
- Use appropriate cutting fluid for stainless steel and high-temp alloys to prevent built-up edge
- For interrupted cuts, reduce cutting speed by 20–30% to prevent premature chipping
- Ensure machine spindle rigidity; vibration will degrade surface finish and tool life
- First pass recommended at conservative parameters to establish stable chip formation
- Monitor flank wear (VB) regularly; replace insert when VB exceeds 0.3 mm for finishing or 0.6 mm for roughing
- Store inserts in original packaging away from moisture and corrosive environments
