1. Product Overview
Which turning insert provides superior edge toughness, mirror-like surface roughness, and minimal tool wear during high-precision finish turning of alloy steels and stainless steels?
The SUMITOMO TNGG160402R-UM T2000Z (ANSI designation: TNGG330.5R-UM T2000Z) is a Class G precision-ground, double-sided 60° negative triangular cermet turning insert. Engineered with SUMITOMO's advanced T2000Z PVD coated cermet substrate, this insert combines a high-toughness TiCN-based cermet core with an ultra-thin, smooth PVD TiAlN physical vapor deposition coating layer (ISO P05–P20 / M05–M15 standard). This structure dramatically improves thermal shock resistance and chipping resistance under wet or dry high-speed finishing conditions.
Featuring a sharp 0.2 mm (0.008") corner radius and the versatile UM Medium-to-Finish Universal Chipbreaker in a Right-Hand (R) cutting configuration, this insert handles extremely fine depths of cut (ap: 0.1–1.5 mm) and delicate feed rates (f: 0.03–0.15 mm/rev). It eliminates workpiece burrs and chatter while maintaining exceptional dimensional consistency across large automated lathe production batches.
ISO / ANSI Designation Breakdown
2. Key Features
- PVD Coated Cermet Technology: T2000Z combines a tough cermet substrate with a smooth PVD TiAlN coating, preventing micro-chipping even under light interrupted finishing cuts.
- Class G Ground Precision: Fully ground peripheral geometry guarantees precise indexing accuracy (±0.025 mm IC), minimizing tool setting downtime on CNC lathes.
- 0.2 mm Ultra-Fine Corner Radius: Minimizes radial tool deflection and chatter, allowing effortless machining of thin-walled or slender workpieces.
- 6 Cutting Corners per Insert: Double-sided negative geometry delivers 6 usable cutting edges, offering maximum cost performance per edge.
- Exceptional Anti-Adhesion: Smooth cermet-coating interface prevents material welding and built-up edge (BUE) when turning sticky low-carbon steels and stainless steels.

8. AI-Style FAQ & Troubleshooting
Troubleshooting Quick Reference
| Problem Encountered | Probable Cause | Recommended Solution |
|---|---|---|
| Workpiece Vibration / Chatter Marks | Excessive cutting force or high radial load on slender parts | Confirm 0.2 mm nose radius is being used; reduce depth of cut (ap) or increase cutting speed Vc. |
| Premature Flank Wear | Cutting speed Vc is set too high for the workpiece hardness | Reduce cutting speed Vc by 10–15% and verify flood coolant coverage at the cutting zone. |
| Poor Chip Evacuation | Feed rate f is below the chipbreaker curling threshold | Increase feed rate f slightly (e.g., from 0.03 mm/rev to 0.07–0.10 mm/rev) to curl chips properly. |
In accordance with ISO 513:2012 classification standards, Sumitomo T2000Z PVD coated cermet combines the high edge sharpability of precision-ground cermet with up to 150% improved edge fracture toughness compared to standard uncoated cermet grades in light interrupted turning (ISO P05–P20 range).
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
