DCMT11T302-MV US735
Precision Finishing | US735 CVD Toughness | Anti-Vibration 0.2mm Radius
Optimized for High-Heat & Low-Pressure Cutting
US735 Grade (The Stainless Specialist): The US735 is a CVD-coated carbide specifically engineered for the M-class (Stainless Steel) group. It utilizes a high-toughness substrate that absorbs the mechanical shocks of interrupted cuts, paired with a coating that resists "built-up edge" (BUE) and thermal fatigue common in 304 and 316 stainless.
MV Chipbreaker (Stable Precision): The MV (Medium-V) geometry is a versatile performer. In this 11T3 size, it provides excellent chip evacuation for finishing passes. It forces chips to curl and break even at shallow depths, preventing "bird-nesting" that can ruin a precision surface finish.
0.2mm Radius (Vibration Control): The sharp "02" nose radius is critical for thin-walled parts. By reducing radial cutting forces, it prevents the workpiece from "pushing away" or vibrating, ensuring tight tolerances and a smooth $Ra$ value.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302-MV | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5-MV | 3/8" | 5/32" | 0.0078" (1/128") |
Recommended Machining Parameters
*US735 excels with coolant. For thin parts, use the lower end of the feed range.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 80 - 150 m/min | 0.04 - 0.12 mm/r | 0.15 - 1.00 mm |
| Martensitic Stainless (420/440C) | 100 - 170 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.20 mm |

US735 (CVD): Optimized for toughness. If you are experiencing edge chipping or thermal cracking in stainless steel, US735 is the most stable choice.
VP15TF (PVD): Switch to VP15TF if you are doing very light, high-speed finishing on small parts where the sharpest possible edge is required to minimize heat generation.

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.
