Product Overview
The DNMG110408GS is a premium-grade indexable carbide turning insert manufactured by Kyocera. Featuring the advanced CA515 substrate and General Semi-Finishing (GS) chipbreaker, this DNMG-style 55° rhombic insert is engineered for high-precision CNC turning operations where repeatability, surface integrity, and tool longevity are paramount. Every insert is manufactured to ISO 1832 standards and inspected for dimensional accuracy within ±0.05 mm.

Grade Details — Key Grade Characteristics
CA515 is a high-performance PVD-coated carbide grade developed by Kyocera for precision-to-medium turning of ferrous materials. The ultra-fine grain substrate (average grain size 0.5 µm) delivers exceptional hardness and edge stability, while the TiAlN-based multi-layer coating provides outstanding thermal barrier protection and oxidation resistance up to 900°C (1,652°F).
- Substrate: Ultra-fine grain tungsten carbide (WC-Co)
- Coating System: TiAlN-based PVD multi-layer coating
- Coating Appearance: Copper-bronze
- Hardness: HRA 92.5
- Transverse Rupture Strength: ≥ 2,800 MPa
- ISO Application Range: Steel (P05–P30), Stainless Steel (M10–M25), Cast Iron (K15–K25)
- Max Operating Temperature: 900°C (1,652°F)
Grade Comparison Matrix

Application Map by Operation
| Operation | Suitability | Recommended Lead Angle | Notes |
|---|---|---|---|
| External Turning | ★★★★★ | 93° (D-type holder) | Primary application; best chip evacuation |
| Internal Turning | ★★★☆☆ | 107° (S-type holder) | Use minimum overhang for rigidity |
| Facing | ★★★★☆ | 45°–93° | Reduce feed at center to avoid chip jamming |
| Profiling | ★★★★☆ | Variable | Smaller nose radius preferred for complex contours |
| Chamfering | ★★★☆☆ | 45° | Light cuts only; verify edge stability |
Recommended Cutting Conditions
Values below are starting recommendations for stable setups with coolant. Adjust based on machine rigidity, workpiece condition, and desired productivity.
| Material | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel | 220–320 | 0.12 – 0.40 mm/rev | 0.8 – 4.0 mm |
| Alloy Steel | 180–280 | 0.12 – 0.40 mm/rev | 0.8 – 4.0 mm |
| Stainless Steel | 120–200 | 0.12 – 0.40 mm/rev | 0.8 – 4.0 mm |
| Gray Cast Iron | 150–220 | 0.12 – 0.40 mm/rev | 0.8 – 4.0 mm |
| Ductile Cast Iron | 130–180 | 0.12 – 0.40 mm/rev | 0.8 – 4.0 mm |
Operating Guidelines
- Coolant: High-pressure coolant (≥ 70 bar) is strongly recommended for stainless steel and alloy steel to extend tool life and improve chip evacuation.
- Entry Strategy: Use a 45° lead-in angle or radius programming to avoid direct radial entry; this minimizes notch wear on the insert nose.
- Speed Ramp: Start at the lower end of the recommended Vc range for the first 10–15 minutes, then ramp up to the optimum based on observed wear patterns.
- Tool Overhang: Keep tool overhang to ≤ 4× tool diameter for external holders and ≤ 5× for internal boring bars to prevent vibration.
- Insert Seat: Ensure the insert seat is clean and free of chip debris before clamping; torque the lever or screw to manufacturer specification (typically 3.5–4.5 N·m).
- Edge Monitoring: Inspect the flank wear (VB) every 30–60 minutes. Retire the insert when VB reaches 0.3 mm for roughing or 0.15 mm for finishing.
- Storage: Store inserts in original packaging at 15–25°C and < 60% relative humidity to prevent coating degradation.
