CCMT09T304 US735
Stainless Steel Workhorse | PVD Coated Carbide | 0.4mm Radius
Material & Coating Science
US735 Grade (PVD Toughness): Engineered specifically for ISO M (Stainless Steel). The PVD (Physical Vapor Deposition) coating is thinner and smoother than CVD, providing the sharp edge necessary to slice through gummy materials like 304 and 316 stainless without causing work-hardening. Its substrate is exceptionally resistant to thermal cracking and notch wear.
0.4mm All-Rounder Radius: The 04 radius (1/64") is the gold standard for finishing. It minimizes radial cutting forces to prevent vibration (chatter) in boring bars while remaining robust enough to handle the varying depths of cut in semi-finishing operations.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51 | 0.375" (3/8") | 0.156" (5/32") | 0.0157" |
Recommended Cutting Parameters
*Stainless steel requires consistent chip loads to prevent work-hardening. Always use high-pressure coolant where possible.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic (304/316) | 90 - 180 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.50 mm |
| Super Alloys (Inconel) | 30 - 60 m/min | 0.05 - 0.12 mm/r | 0.20 - 1.20 mm |

US735 (PVD): The Stainless Steel Master. It features a tougher substrate designed specifically for gummy materials. Choose this for dedicated stainless production to maximize tool life.
VP15TF (PVD): The Versatile Hybrid. If you frequently switch between mild steel and stainless steel on the same lathe, VP15TF offers a better compromise across multiple material groups.

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.
