Product Overview
The VNMG160412KG CA310 TMC07704 is a precision-engineered indexable carbide turning insert manufactured by Kyocera in Japan. Designed for CNC turning centers and milling machines, this insert delivers mirror surface finish, dimensional accuracy, and extended tool life across high-volume production environments. The CA310 PVD-coated grade ensures optimized chip control and reduced cutting forces, making it the preferred choice for general manufacturing.

Grade Details — Key Grade Characteristics
The CA310 grade is a PVD multi-layer coated carbide grade engineered for general turning of steel, stainless steel, and cast iron.
- Coating: PVD Multi-layer (TiAlN-based)
- Substrate: Fine-grain WC-Co Carbide
- Coating Color: Bronze/Copper
- Hardness: HRA 92.5
- Transverse Rupture Strength: ≥ 3,500 MPa
- Primary Applications: Steel (P), Stainless Steel (M), Cast Iron (K)
- Recommended Speed: 80–250 m/min (depending on material)
- Recommended Feed: 0.10–0.40 mm/rev
- Depth of Cut: 0.5–4.0 mm
Performance Profile: Excellent balance of wear resistance and toughness. Optimized for stable to semi-interrupted cuts. Superior crater and flank wear resistance at medium-to-high speeds.
Grade Comparison Matrix
Compare CA310 with adjacent grades in the Kyocera portfolio to select the optimal grade for your application:
| Grade | Coating | ISO Range | Best For | Speed | Toughness |
|---|---|---|---|---|---|
| CA310 | PVD TiAlN | P15–P30, M15–M25, K15–K25 | General Steel, SS, Cast Iron | Medium–High | High |
| CA320 | PVD TiAlN | P25–P40, M20–M30 | Heavy Roughing, Interrupted Cuts | Medium | Very High |

Chipbreaker Profile
The VNMG160412KG utilizes a KG (Medium machining) chipbreaker designed for versatile semi-finishing to medium-roughing applications.
- Land Width: Medium, 0.15–0.20 mm for balanced edge strength and finish
- Groove Depth: Medium (0.12–0.18 mm) for reliable chip breaking across feed ranges
- Rake Angle: Positive 12–15° offering good chip flow with adequate edge support
- Chip Control: Effective chip breaking from 0.10–0.30 mm/rev feed rates
- Best For: General-purpose CNC turning, semi-finishing, medium stock removal
Recommended Applications & Workpiece Materials
The VNMG160412KG with CA310 grade is optimized for the following material groups:
- Carbon Steel (C45, C50, C60): Excellent — continuous to lightly interrupted cuts, high speed capability
- Alloy Steel (4140, 4340, 8620): Excellent — balanced wear resistance and toughness
- Stainless Steel (304, 316, 420): Very Good — reduced built-up edge tendency due to PVD coating
- Gray Cast Iron (GG25, GG30): Very Good — dry or wet machining, good crater resistance
- Ductile Cast Iron (GGG40, GGG50): Good — moderate speeds, stable cutting edges
- Tool Steel (H13, D2, O1 annealed): Good — reduced speeds for hardness >250 HB
- Free-Machining Steel (12L14, 1215): Excellent — high speeds, excellent finish
Application Map by Operation
Suitability rating for common CNC turning operations:
| Operation Type | Suitability | Recommended Conditions |
|---|---|---|
| External Turning | ★★★★★ Excellent | Continuous to light interrupted cuts |
| Internal Turning (Boring) | ★★★★☆ Very Good | Stable boring bars, min. 1.5×D overhang |
| Face Turning | ★★★★★ Excellent | High feed rates for productivity |
| Profiling / Contouring | ★★★★☆ Very Good | Use smaller corner radius for accuracy |
| Heavy Roughing | ★★★☆☆ Good | Reduce speed 15–20% for stability |
Recommended Cutting Conditions
Starting parameters for VNMG160412KG CA310. Adjust based on machine rigidity and workpiece setup:
| Workpiece Material | Hardness (HB) | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|---|
| Carbon Steel / Alloy Steel | 150–250 | 120–180 | 0.20–0.40 | 1.5–4.0 |
| Stainless Steel (Austenitic) | 150–220 | 80–120 | 0.20–0.40 | 1.5–4.0 |
| Gray / Ductile Cast Iron | 180–260 | 100–150 | 0.20–0.40 | 1.5–4.0 |
| Tool Steel (Annealed) | 200–300 | 80–140 | 0.10–0.20 | 0.5–2.0 |
Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece stability. Wet cutting recommended for stainless steel and high-temp alloys.
Operating Guidelines
Best practices to maximize tool life and surface quality:
- Coolant: Flood coolant recommended for steel and stainless steel at speeds >150 m/min. Minimum 5% soluble oil concentration. For cast iron, dry machining acceptable at moderate speeds.
- Edge Preparation: As-supplied T-land edge preparation (0.05–0.10 mm × 20°). Do not re-hone; PVD coating integrity is compromised by manual honing.
- Tool Overhang: Keep toolholder overhang ≤ 1.5× shank diameter for boring. For external turning, rigid setup essential for 1.2 mm corner radius.
- Runout: Maintain spindle runout < 0.01 mm TIR. Excessive runout accelerates flank wear and chipping.
- Entry/Exit: Use ramp entry or radius approach. Avoid direct plunge into workpiece. Reduce feed by 30% during entry and exit phases.
- Chip Management: Ensure chip conveyor or enclosure is rated for 35 insert chips. Long chips indicate feed or speed is too low.
- Insert Change: Replace when flank wear (VB) reaches 0.3 mm, or when crater wear (KT) exceeds 0.15 mm. Do not wait for catastrophic failure.
- Storage: Keep original packaging sealed until use. Avoid contact with corrosive agents. Handle with gloves to prevent coating contamination.
