CCMT060202 US735
Stainless Steel Specialist | PVD Coated Carbide | 0.2mm Precision Radius
Material Science & Precision Edge
US735 Grade (PVD Tough Carbide): Engineered for the toughest challenges in Stainless Steel (ISO M) and Super Alloys (ISO S). The PVD (Physical Vapor Deposition) coating provides a sharper edge than CVD alternatives, which is vital for slicing through gummy materials without causing work-hardening. The substrate is exceptionally tough, preventing notch wear and edge chipping.
0.2mm Sharp Radius (Micro-Finishing): The 02 radius is optimized for light finishing and micro-boring. It reduces radial cutting pressure, making it the perfect choice for high-precision CNC setups where preventing vibration and maintaining tight dimensional tolerances are the highest priority.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060202 | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | CCMT21.50.5 | 1/4" | 3/32" | 0.0079" |
Recommended Cutting Parameters
*US735 requires lower speeds but higher reliability. Always use high-pressure coolant for stainless applications.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 80 - 180 m/min | 0.03 - 0.12 mm/r | 0.10 - 0.80 mm |
| Heat Resistant Alloys (Inconel) | 30 - 60 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.50 mm |

US735 (PVD): The Toughness Leader. Specifically designed to prevent sudden breakage in gummy stainless steels. Use this when tool life consistency is your primary bottleneck.
VP15TF (PVD): The General Versatility choice. Excellent for a wide range of materials (Steel, Stainless, Cast Iron). If you only want to stock one grade for everything, choose VP15TF. If you want the best performance for Stainless specifically, stick with **US735**.

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.
