1. Product Overview
The TNMG160408PQ is a premium-grade indexable carbide turning insert manufactured by Kyocera under grade CA510. Designed for modern CNC turning centers, this insert combines an advanced micro-grain carbide substrate with a high-performance PVD TiAlN coating to deliver exceptional wear resistance, thermal stability, and cutting-edge integrity. The Triangle (60°) geometry with 0.8 mm nose radius ensures optimal chip formation and surface finish quality across a wide spectrum of ferrous and non-ferrous materials.
Each insert is precision-ground to tight tolerances and features a robust chipbreaker geometry optimized for semi-finishing, general turning. Whether you are performing high-speed finishing or medium-duty roughing, the TNMG160408PQ provides consistent, repeatable performance that reduces cycle times and lowers cost-per-part.

5. Grade Comparison Matrix
Select the optimal grade for your application by comparing Kyocera's most popular turning grades:
| Grade | Coating | Hardness | Best For | Speed (m/min) |
|---|---|---|---|---|
| CA510 | PVD TiAlN | 92.5 HRA | Steel, Stainless Steel | 150–280 |
| CA511 | PVD TiAlN+TiN | 92.0 HRA | General Steel | 120–250 |
| CA515 | PVD AlTiN | 93.0 HRA | Hardened Steel (>45 HRC) | 80–180 |
| CA520 | CVD TiC-TiCN-Al2O3 | 91.5 HRA | Heavy Roughing | 100–200 |
6. Chipbreaker Profile — Light to Medium Machining
The PQ chipbreaker geometry on the TNMG160408PQ is specifically engineered for Semi-finishing, general turning. The land width, groove depth, and rake angle are optimized to:
- Control chip flow direction and prevent nesting on the workpiece or toolholder
- Reduce cutting forces by up to 15% compared to flat-top inserts
- Minimize built-up edge (BUE) when machining sticky materials like stainless steel
- Produce tightly curled chips that are safely evacuated through the machine chip conveyor
- Enable higher cutting speeds without compromising surface integrity
Chipbreaker Recommendation: The PQ profile is best suited for carbon steel, alloy steel, stainless steel with depths of cut ranging from 0.10–0.50 mm and feeds from 0.10–0.25 mm/rev.
7. Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability | Key Benefit |
|---|---|---|---|
| Carbon & Alloy Steels | C45, 42CrMo4, 16MnCr5 | ★★★★★ Excellent | High speed, long tool life |
| Stainless Steels | 304, 316, 17-4PH | ★★★★☆ Very Good | Reduced BUE, clean finish |
| Tool & Die Steels | H13, D2, O1 | ★★★☆☆ Good | Wear resistance at moderate speeds |
| Cast Irons | GG25, GGG40, CGI | ★★★★☆ Very Good | Abrasion resistance, thermal stability |
| High-Temp Alloys | Inconel 718, Ti-6Al-4V | ★★★☆☆ Good | Chemical stability at high temps |
8. Application Map by Operation
| Operation Type | Suitability | Recommended Conditions |
|---|---|---|
| External Turning | ★★★★★ Excellent | Continuous cut, stable setup |
| Internal Turning / Boring | ★★★★☆ Very Good | Minimize overhang, rigid holder |
| Facing | ★★★★★ Excellent | Center-height alignment critical |
| Profiling / Contouring | ★★★★☆ Very Good | Use reduced feed for accuracy |
| Grooving / Cut-off | ★★☆☆☆ Limited | Not recommended—use dedicated inserts |
9. Recommended Cutting Conditions
The following parameters are starting recommendations for the TNMG160408PQ with grade CA510. Adjust based on machine rigidity, workpiece condition, and desired surface finish.
| Workpiece Material | Cutting Speed Vc (m/min) | Depth of Cut ap (mm) | Feed fn (mm/rev) |
|---|---|---|---|
| Carbon Steel (C45) | 180–280 | 0.10–0.50 | 0.10–0.25 |
| Alloy Steel (42CrMo4) | 150–220 | 0.10–0.50 | 0.10–0.25 |
| Stainless Steel (304) | 120–180 | 0.10–0.50 | 0.08–0.20 |
| Cast Iron (GG25) | 100–160 | 0.20–0.80 | 0.10–0.30 |
Note: Values shown are ranges. Start at the lower end for unstable setups or interrupted cuts. Increase speed gradually while monitoring tool wear and surface finish.
10. Operating Guidelines
- Tool Overhang: Keep toolholder overhang to a minimum (≤ 4× shank diameter) to prevent vibration and chatter.
- Center Height: Position insert cutting edge exactly at workpiece centerline (±0.1 mm) for optimal chip formation and insert life.
- Coolant: High-pressure coolant (70–100 bar) is recommended for stainless steel and high-temp alloys. For cast iron, dry machining or minimal coolant is often preferred to avoid thermal shock.
- Insert Seat: Inspect the toolholder seat for wear or debris before mounting. A damaged seat reduces insert life by up to 40%.
- Clamping Torque: Torque the clamping screw to 2.5–3.5 Nm. Over-tightening causes micro-cracking; under-tightening leads to movement and fracture.
- Flank Wear Limit: Replace the insert when uniform flank wear (VB) reaches 0.3 mm, or earlier if notch wear, crater wear, or chipping is observed.
- Entry/Exit Strategy: Use ramp-down or arc-in entries to avoid impact loading on the insert nose. Never plunge radially into solid material.
11. Toolholder Compatibility
| Holder Type | Compatible Series | Shank Size | Approach Angle |
|---|---|---|---|
| External Turning | MTJNR/L 16xx, DTJNR/L 16xx, STGCR/L 16xx, PTGCR/L 16xx | 20×20 mm, 25×25 mm | 93° (MTJNR), 93° (DTJNR), 91° (STGCR), 91° (PTGCR) |
| Internal Turning | S16-STFCR/L, A16-STFCR/L | Ø16–Ø32 mm | 91° |
| Screw Clamp | Standard lever-lock or top-screw systems | Universal | Compatible with all 60° triangle holders |
Always verify holder insert seat angle (usually 0° for TNMG) and pocket size (IC 16) before ordering.
