CPMH080204-SV US735
Stainless Finishing Master | US735 Impact Toughness | SV Sharp Geometry
Optimized for Precision in Tough Materials
US735 Grade (The Stainless Guardian): The US735 is a premium CVD-coated grade designed specifically for M-Class (Stainless Steel). While many finishing grades are brittle, US735 is engineered for "Impact Toughness." It resists thermal cracking and edge chipping when finishing stainless steel parts with interrupted cuts or raw surface scale, ensuring high reliability.
SV Chipbreaker (Super-Finishing Sharpness): The SV geometry is a light-cutting (small-cut) breaker. Its sharper edge reduces cutting forces significantly compared to the MV series. This is critical when finishing thin-walled tubes or small-diameter bores where tool pressure causes vibration or dimensional inaccuracy.
0.4mm (1/64") Precision Radius: The 04 radius provides the ultimate surface finish and allows the tool to track tight profiles. It generates the lowest radial pressure, making it the perfect partner for slender boring bars.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH080204-SV | 7.94 mm | 2.38 mm | 0.40 mm |
| Imperial | CPMH2.521-SV | 5/16" | 3/32" | 0.0157" (1/64") |
Precision Stainless Cutting Parameters
*SV geometry is designed for light depths. Avoid excessive feed rates to prevent chip clogging.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless 304/316 | 100 - 180 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.00 mm |
| Duplex / Inconel | 40 - 90 m/min | 0.03 - 0.10 mm/r | 0.08 - 0.80 mm |
Pro-Tip: SV vs. MV Chipbreaker
SV (Small-cut): Use this when your depth of cut is very shallow (under 1.0mm). It is much better at breaking chips at low feed rates.
MV (Medium-cut): Switch to the MV chipbreaker for general semi-roughing or when the depth of cut exceeds 1.5mm to ensure better chip evacuation.

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.
