CPMH090308-MV US735
Impact Strength Powerhouse | US735 CVD Toughness | MV Medium-Cut Control
Built for Maximum Stainless Productivity
US735 Grade (The Impact Guard): The US735 is a high-toughness CVD-coated carbide specifically developed for M-Class (Stainless Steel). It is the gold standard for handling interrupted cuts, scale, and unstable machining conditions. The coating provides a thermal barrier that resists the extreme heat of stainless machining while the ultra-tough substrate prevents sudden edge breakage.
MV Chipbreaker (The Versatile Wedge): The MV geometry features an 11-degree positive rake designed to reduce cutting forces. In gummy materials like 316 stainless, the MV breaker aggressively curls and snaps the chip, preventing the "long-string" entanglement that damages parts and tool holders.
0.8mm (1/32") High-Strength Radius: The 08 radius provides a significantly more robust edge than the 04 version. It allows for higher feed rates and deeper cuts, dissipating heat across a wider surface area to extend tool life during heavy semi-finishing.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH090308-MV | 9.525 mm | 3.18 mm | 0.80 mm |
| Imperial | CPMH322-MV | 3/8" | 1/8" | 0.0315" (1/32") |
Stainless Steel Cutting Parameters
*The 0.8mm radius allows for higher feed rates. Always use high-pressure coolant to prevent built-up edge (BUE).
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic (304/316) | 80 - 160 m/min | 0.10 - 0.28 mm/r | 0.50 - 3.00 mm |
| High Strength (Duplex) | 50 - 110 m/min | 0.08 - 0.22 mm/r | 0.40 - 2.00 mm |

Shop 09 Series HoldersPro-Tip: US735 vs. US7020
US735 (The Heavy Rougher): Choose this for unstable setups, interrupted cuts, or heavy scale. It prioritize "Not Breaking" above all else.
US7020 (The Smooth Runner): Switch to US7020 for continuous, stable turning at higher speeds to achieve better surface finishes and flank wear resistance.

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.
