Grade Details — Key Grade Characteristics
The CA310 grade is a cornerstone of Kyocera's coated carbide portfolio, engineered for versatility across ferrous materials:
- Substrate: Fine-grained tungsten carbide (WC-Co) with 10% cobalt content
- Coating System: CVD Multi-layer: TiCN (base) + Al₂O₃ (intermediate) + TiN (top)
- Visual Identification: Gold/Black surface finish
- Hardness: HRA 91.5–92.0
- Transverse Rupture Strength: ≥ 2,400 N/mm²
- ISO Application Range: ISO P10–P30, K20–K30, M15–M25
Key Performance Characteristics:
- Excellent wear resistance in continuous and light-interrupted cuts
- High thermal stability up to 900°C cutting temperature
- Superior crater wear resistance due to thick Al₂O₃ layer
- Good balance between toughness and hardness
- Optimized for medium to high cutting speeds (150–350 m/min)
- Reduced built-up edge formation on alloy steels
Recommended Workpiece Materials: Carbon steels, alloy steels, tool steels, cast irons, and martensitic stainless steels

| Speed Range | Medium-High | Medium | Low-Medium | High |
Chipbreaker Profile
KG Chipbreaker: Robust chipbreaker geometry with reinforced cutting edge for medium roughing (1.0–4.0 mm). Balanced between chip control and edge strength. Wide groove accommodates higher feed rates.
This chipbreaker geometry is specifically paired with the CA310 grade to achieve optimal performance in medium roughing operations. The combination of substrate toughness and coating hardness ensures reliable chip control even under variable cutting conditions.
Recommended Applications & Workpiece Materials
- Carbon Steels: C15 through C60 — excellent for continuous and lightly interrupted cuts
- Alloy Steels: 16MnCr5, 42CrMo4, 34CrNiMo6 — balanced wear and toughness
- Tool Steels: H13, D2 (annealed) — moderate speeds with adequate coolant
- Cast Irons: GG25, GG30, GGG40, GGG50 — dry or minimal coolant machining
- Stainless Steels: 1.4301 (304), 1.4401 (316), 1.4021 (420) — emulsion coolant essential
- Heat-Resistant Alloys: Limited suitability; reduce Vc by 30–40% from steel values
Application Map by Operation
The CNMG120408KG CA310 is rated across common turning operations:
| Operation Type | Suitability | Recommended Depth (ap) | Feed Rate (fn) |
|---|---|---|---|
| External Turning | ⭐⭐⭐⭐⭐ Excellent | 1.5–6.0 mm | 0.25–0.60 mm/rev |
| Internal Turning (Boring) | ⭐⭐⭐⭐☆ Very Good | 1.5–6.0 mm | 0.25–0.60 mm/rev |
| Face Turning | ⭐⭐⭐⭐⭐ Excellent | 1.5–6.0 mm | 0.25–0.60 mm/rev |
| Profiling / Contouring | ⭐⭐⭐☆☆ Moderate | 0.5–3.0 mm | 0.10–0.30 mm/rev |

| Heavy Roughing | ⭐⭐⭐⭐⭐ Excellent | 2.0–8.0 mm | 0.30–0.60 mm/rev |
Recommended Cutting Conditions
Parameters are starting recommendations. Fine-tune based on machine rigidity, workpiece condition, and required surface quality:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) | Coolant |
|---|---|---|---|---|
| Low-Carbon Steel (C15–C35) | 120–200 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Emulsion / Dry |
| Medium-Carbon Steel (C45–C60) | 120–200 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Emulsion recommended |
| Alloy Steel (42CrMo4, 16MnCr5) | 120–200 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Emulsion / High-pressure |
| Stainless Steel (304, 316) | 80–150 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Emulsion essential |
| Gray Cast Iron (GG25, GG30) | 100–180 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Dry / Compressed air |
| Nodular Cast Iron (GGG40, GGG50) | 100–180 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Dry preferred |
| Tool Steel (H13, D2, Annealed) | 120–200 m/min | 0.25–0.60 mm/rev | 1.5–6.0 mm | Emulsion / Oil |
Note: Values assume stable setup and adequate coolant delivery. Reduce speeds by 15–20% for interrupted cuts or slender workpieces.
Operating Guidelines
- Tool Overhang: Minimize overhang to reduce vibration. Use shortest possible toolholder for rigidity.
- Insert Positioning: Ensure insert sits flush in pocket. Verify clamping force (torque: 2.5–3.5 Nm for M2.5 screws).
- Cutting Edge Preparation: CNMG120408KG features 0.8 mm corner radius — ideal for heavy roughing and high feeds.
- Chip Control: Monitor chip color. Blue/purple chips indicate optimal temperature; dark brown suggests excessive heat.
- Coolant Strategy: Flood coolant at 5–8% concentration for steel. For cast iron, dry machining is preferred to avoid thermal cracking.
- Speed Ramp: Start at lower end of Vc range and increase gradually. Watch for crater wear on rake face.
- Edge Life Indicators: Replace insert when flank wear (VB) exceeds 0.3 mm, or when surface finish degrades noticeably.
- Workpiece Security: Ensure proper clamping to avoid chatter. Use steady rests for long slender shafts.
Toolholder Compatibility
The CNMG120408KG insert is compatible with standard 80° rhombic toolholders. The following Kyocera and industry-standard holders are verified matches:
| Toolholder Model | Insert Shape | Capacity | Clamping |
|---|---|---|---|
| MCLNR/L 1212H09 | 80° Rhombic | 12 mm | Standard / Lever lock |
| MCLNR/L 1616H12 | 80° Rhombic | 12 mm | Standard / Lever lock |
