Product Overview
The VNMG160412KG CA320 TME07704 is a premium rhombic 35° negative indexable insert manufactured by Kyocera in Japan. Designed for heavy roughing, this insert delivers standard surface finish with exceptional dimensional stability and extended tool life in demanding CNC environments.
Engineered with a TiCN + Al₂O₃ CVD multi-layer coating over a WC-Co substrate, the CA320 grade provides outstanding wear resistance and thermal stability during high-speed machining of steel, cast iron. The KG chipbreaker geometry ensures optimal chip formation and evacuation, reducing downtime and improving surface integrity.

Grade Details — Key Grade Characteristics
Grade CA320 is a CVD-coated carbide grade optimized for heavy roughing operations in ferrous materials. Key characteristics include:
- Coating System: TiCN + Al₂O₃ multi-layer CVD coating providing excellent thermal barrier and crater wear resistance
- Substrate: WC-Co micro-grain carbide with high cobalt content for enhanced toughness
- Hardness: ~1,450 HV (Vickers) for superior abrasion resistance
- Transverse Rupture Strength: >2,800 MPa — ideal for interrupted cuts and heavy loads
- Operating Temperature: Up to 1,000°C in the cutting zone
- Color Identification: Gold-bronze top surface with black peripheral coating
Grade Comparison Matrix
Select the optimal grade for your application by comparing CA320 with adjacent grades in the Kyocera portfolio:
| Grade | Coating | Application | Material Range |
|---|---|---|---|
| CA320 | TiCN + Al₂O₃ (CVD) | Medium to Roughing | Steel, Cast Iron, Stainless |
| CA315 | TiCN + Al₂O₃ (CVD) | Light to Medium | Steel, Stainless Steel |
| CA310 | TiCN + Al₂O₃ (CVD) | Finishing to Medium | Steel, General Purpose |
| CA325 | TiCN + Al₂O₃ + TiN (CVD) | Heavy Roughing | Cast Iron, Hard Steel |
Chipbreaker Profile
The KG chipbreaker on the VNMG160412KG is engineered for heavy roughing applications. Its macro-geometry features a carefully calculated rake angle and groove depth that promotes:
- Controlled chip curling and breakage into manageable segments
- Reduced cutting forces and heat generation at the tool tip
- Improved surface finish through stable chip evacuation
- Minimized built-up edge (BUE) when machining sticky materials like stainless steel
The chipbreaker land width and depth are optimized for the 1.2 mm nose radius, ensuring balanced chip flow across all engaged cutting edges.
Recommended Applications & Workpiece Materials
The VNMG160412KG CA320 is recommended for the following material groups and applications:
- Carbon Steel: C35, C45, C60 — continuous to lightly interrupted turning
- Alloy Steel: 4140, 4340, 8620 — medium to roughing operations
- Stainless Steel: 304, 316, 420 — general turning with stable setups
- Cast Iron: GG25, GGG40 — facing and external turning
- Tool Steel: H13, D2 — pre-hardened material machining at reduced speeds
Application Map by Operation
Use this matrix to identify the best operational fit for the VNMG160412KG insert:
| Operation | Suitability | Recommended Conditions |
|---|---|---|
| External Turning | ⭐⭐⭐⭐⭐ Excellent | Continuous to light interrupted cuts |
| Internal Boring | ⭐⭐⭐⭐☆ Very Good | Stable workpiece, rigid setup |
| Facing | ⭐⭐⭐⭐⭐ Excellent | Face to center, moderate feeds |
| Profiling | ⭐⭐⭐☆☆ Good | Use reduced feeds for accuracy |
| Heavy Roughing | ⭐⭐⭐⭐⭐ Excellent | Max depth of cut, rigid setup |
Recommended Cutting Conditions
Start with these parameters and fine-tune based on machine rigidity, workpiece condition, and required surface finish:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (≤ 450 HB) | 120-250 | 0.20-0.60 | 1.0-6.0 |
| Alloy Steel (≤ 550 HB) | 120-220 | 0.10-0.30 | 0.5-3.5 |
| Stainless Steel | 100-180 | 0.08-0.25 | 0.5-2.5 |
| Cast Iron (GG/GGG) | 100-200 | 0.12-0.40 | 1.0-5.0 |
Note: Reduce cutting speed by 15-20% for interrupted cuts or less rigid setups. Use coolant for stainless steel and alloy steel applications to extend tool life.
Operating Guidelines
- Tool Overhang: Minimize overhang to reduce vibration and improve surface finish. Use the shortest possible toolholder.
- Insert Seating: Ensure the insert pocket is clean and free of chips before seating. Torque to manufacturer specifications.
- Coolant: High-pressure coolant (70+ bar) is recommended for chip evacuation in deep cavities and bore operations.
- Edge Preparation: The VNMG160412KG features a honed T-land edge preparation for enhanced edge strength and chipping resistance.
- Index Frequency: Index the insert when flank wear reaches 0.3 mm or when surface finish degrades beyond specification.
- Storage: Store inserts in original packaging away from direct sunlight and moisture to preserve coating integrity.
