Product Overview
The VNMG160402GP CA025P TMH00309 is a precision-engineered 35° rhombic carbide turning insert manufactured by Kyocera. Designed for medium machining, this negative-insert (0° clearance) features a 0.2 mm nose radius and 4.76 mm thickness. The GP chipbreaker geometry ensures controlled chip flow and reduced cutting forces, delivering repeatable dimensional accuracy and superior surface finish across high-volume CNC production runs.

Grade Details – Key Grade Characteristics
CA025P is a CVD-coated carbide grade engineered for steel machining (ISO P-class). The substrate combines a tough gradient carbide core with a multi-layer coating of TiCN, Al₂O₃, and TiN. This architecture provides:
- Exceptional crater and flank wear resistance at elevated cutting temperatures
- High adhesion strength between coating and substrate preventing delamination
- Optimized thermal barrier properties for consistent performance in wet and dry machining
- Balanced toughness and hardness suitable for continuous and lightly interrupted cuts
Grade Comparison Matrix
| Grade | Coating | ISO Range | Best For |
|---|---|---|---|
| CA025P | TiCN/Al₂O₃/TiN CVD | P15 – P35 | Medium-to-high speed steel turning |
| CA025P | TiCN/Al₂O₃/TiN CVD | P15 – P35 | General steel machining, stable conditions |
| CA5525 | PVD (TiAlN) | P10 – P30 | Interrupted cuts and lower speeds |
| PR930 | PVD | P20 – P40 | Heavy roughing and forged surfaces |
Chipbreaker Profile
GP Chipbreaker: Open-groove geometry with positive rake angle for smooth chip evacuation in medium cutting depths.
General Purpose chipbreaker for medium machining
Recommended Applications & Workpiece Materials
Carbon steel, alloy steel, and general structural steels (ISO P15-P35).
- Shaft turning and facing operations on CNC lathes
- External diameter (OD) and internal diameter (ID) boring
- Continuous cutting and light interrupted cutting profiles
- Dry machining or minimal coolant applications
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★★ | Ideal for straight and tapered diameters |
| Facing | ★★★★☆ | Use reduced feed at center to avoid chip jamming |
| Profiling | ★★★☆☆ | Limited by nose radius; larger radii reduce corner clearance |
| Parting Off | ★☆☆☆☆ | Not recommended; use dedicated parting inserts |
| Threading | ☆☆☆☆☆ | Not applicable; use thread-turning inserts |
Recommended Cutting Conditions
| Parameter | Recommended Range | Optimal Starting Point |
|---|---|---|
| Cutting Speed (Vc) | 150 – 250 m/min | 200 m/min (medium carbon steel) |
| Feed Rate (fn) | 0.15 – 0.40 mm/rev | 0.25 mm/rev |
| Depth of Cut (ap) | 0.5 – 3.0 mm | 1.5 mm |
Values are indicative for medium-carbon steel (C45/1045). Reduce speed by 15–20% for alloy steels and increase by 10–15% for free-cutting steels.
Operating Guidelines
- Ensure insert seat and toolholder pocket are clean before clamping to avoid micro-vibration.
- Use adequate coolant concentration (8–10%) for steel machining to prevent built-up edge (BUE).
- Verify tool overhang is minimized; excessive overhang reduces rigidity and accelerates wear.
- Monitor flank wear (VB) regularly; replace insert when VB reaches 0.3 mm to maintain surface quality.
- For interrupted cuts, reduce cutting speed by 20–30% to prevent thermal shock and edge chipping.
- Always use appropriate personal protective equipment (PPE) when handling sharp carbide inserts.
Toolholder Compatibility
Compatible Holder Families: MVJNR, MVQNR, SVJCR, SVQCR, DVJNR, DVQNR series toolholders
35° rhombic negative inserts with 0° clearance require lever-lock or screw-clamp holders with corresponding V-seat angles.
Ensure the toolholder seat angle matches the insert shape (V-seat) and the clamping mechanism (lever or screw) is rated for negative inserts with 0° clearance.
