Product Overview
The TNMG160404PMG CA115P TML00492 is a premium triangle insert manufactured by Kyocera in Japan. Engineered for medium-duty turning applications, this negative-style insert offers three usable cutting edges per side, delivering exceptional cost-per-edge economy. The versatile geometry for general turning. With 16mm inscribed circle diameter, 4.76mm thickness, and 0.4mm nose radius, this insert provides optimal cutting geometry for medium-duty turning operations on CNC turning centers. The PMG (Positive Medium Groove) geometry combined with CA115P PVD coating ensures reliable chip control, extended tool life, and consistent surface finish across a broad spectrum of steel workpiece materials.

- Coating: Multi-layer PVD, 2–4 μm total thickness
- Hardness: 1,600 HV (Vickers hardness)
- Transverse Rupture Strength: 2,800 MPa
- Application Group: ISO P15 (steel machining)
- Max Operating Temperature: 800°C
- Best For: Steel finishing & semi-finishing
Grade Comparison Matrix

|---|---|---|---|---|---|
| CA115P | PVD TiAlN/TiN | P15 | High | Excellent | Steel finishing & semi-finishing |
| CA125P | PVD TiAlN | P25 | Medium-High | Good | General steel machining |
| CA135P | PVD TiAlN | P35 | Medium | Good | Heavy-duty steel roughing |
| PR660 | CVD TiC-TiCN-Al₂O₃ | P20-P30 | Medium | Good | Interrupted steel cutting |
| PR930 | CVD Multi-layer | P30-P40 | Low-Medium | Fair | Heavy roughing & cast iron |
Chipbreaker Profile
The TNMG160404PMG features the PMG (Positive Medium Groove) chipbreaker, ground onto the negative insert substrate to create an effective positive rake geometry. This design combines the economy of double-sided negative inserts with the chip control benefits of a positive groove, making it ideal for medium-duty steel turning.
- Medium-width groove for balanced chip control across feed ranges
- Positive rake angle generated by chipbreaker geometry
- Optimized for medium depths of cut (0.5–3.0mm)
- Reliable chip curl and breakage for steel machining
- Reduced cutting forces compared to flat-top negative inserts
- Suitable for both continuous and lightly interrupted cuts
Recommended Applications & Workpiece Materials
The TNMG160404PMG CA115P is optimized for the following materials and application scenarios:
- Carbon Steels: C35, C45, C50, 1045, 1050 — Excellent performance
- Alloy Steels: 4140, 4340, 16MnCr5, 20MnCr5 — Consistent tool life
- Tool Steels: H13, D2, O1 — Pre-hardened material machining
- Bearing Steels: 100Cr6, 52100 — Precision surface requirements
- Cast Steels: GS-25, GS-45 — General cast steel components
Note: For austenitic stainless steels (304, 316), consider grade CA6535 or PR1225 for optimal performance.
Application Map by Operation
| Operation | Feed Range | Depth of Cut | Performance |
|---|---|---|---|
| External Turning | 0.12–0.35 mm/rev | 0.5–3.0 mm | Reliable chip control |
| Face Turning | 0.10–0.30 mm/rev | 0.5–2.5 mm | Good surface finish |
| Internal Boring | 0.08–0.25 mm/rev | 0.3–1.5 mm | Stable at medium speeds |
| Profiling | 0.08–0.20 mm/rev | 0.3–1.0 mm | Consistent accuracy |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed (f) | Depth of Cut (ap) |
|---|---|---|---|
| Low-Carbon Steel (<0.25% C) | 160–300 m/min | 0.12–0.40 mm/rev | 0.5–3.5 mm |
| Medium-Carbon Steel (0.25–0.6% C) | 144–270 m/min | 0.12–0.40 mm/rev | 0.5–3.5 mm |
| High-Carbon Steel (>0.6% C) | 128–240 m/min | 0.12–0.40 mm/rev | 0.5–3.5 mm |
| Alloy Steel (Cr-Mo series) | 136–255 m/min | 0.12–0.40 mm/rev | 0.5–3.5 mm |
| Pre-Hardened Steel (30–45 HRC) | 112–210 m/min | 0.12–0.40 mm/rev | 0.5–3.5 mm |
Values are starting recommendations. Adjust based on machine rigidity, coolant application, and workpiece condition. Use lower end for interrupted cuts or less rigid setups.
Operating Guidelines
- Coolant: Flood coolant recommended at 6–8% concentration for optimal chip evacuation and thermal management. Minimum flow rate 5 L/min directed at the cutting edge. For hard turning (PQ chipbreaker), consider minimum quantity lubrication (MQL) or dry cutting to avoid thermal shock.
- Tool Overhang: Keep tool overhang to minimum possible (≤4× shank diameter for boring bars). Excessive overhang promotes vibration and chatter marks, especially with larger 16mm inserts.
- Insert Seating: Clean toolholder pocket and insert seat thoroughly before mounting. Negative inserts require precise seating for both top and bottom surfaces. Use torque wrench for screw clamping (recommended 2.5–3.5 N·m).
- Edge Preparation: Do not touch the cutting edge with bare fingers. Oils and moisture can promote micro-chipping at high temperatures. Handle inserts with clean gloves or edge protectors.
- Wear Monitoring: Monitor for flank wear (VBmax = 0.3mm) and crater wear (KT = 0.15mm). Replace insert before catastrophic failure to protect workpiece surface. With 3 edges per side, index promptly when wear limits are reached.
- Speed Ramping: When starting a new batch, begin at 70% of recommended Vc and increase incrementally to find the stable operating window for your specific machine and setup. For PMG chipbreaker, optimal performance is typically achieved at 80–90% of max Vc.
- Index Strategy: As a double-sided negative insert, this tool offers 3×2 = 6 total cutting edges. Index systematically to maximize economy and maintain consistent tool life tracking.
Toolholder Compatibility
The TNMG160404PMG is compatible with standard MTJNR/L and PTJNR/L toolholders designed for triangle negative inserts with 16mm IC. The three cutting edges provide a balance between economy and versatility, making it one of the most popular insert shapes in CNC turning.
- Toolholder series: MTJNR, MTJNL, PTJNR, PTJNL
