CPMH090304-SV US735
High-Toughness Finisher | US735 Impact Barrier | SV Precision Geometry
Engineered for Precision in Harsh Conditions
US735 Grade (Stainless Impact Specialist): The US735 is a CVD-coated grade that defies the standard "brittle" nature of finishing tools. Specifically optimized for M-Class (Stainless Steel), it features a unique substrate that absorbs mechanical shock. This makes it ideal for finishing passes on parts with cross-holes, keyways, or uneven surfaces that would otherwise shatter a standard finishing grade.
SV Chipbreaker (Low-Force Precision): The SV geometry is a light-cutting, small-cut chipbreaker. It features a highly positive rake angle that "slices" rather than "pushes" the material. This sharp action is critical for preventing work-hardening of the stainless surface and reducing radial forces that cause chatter in slender boring bars.
0.4mm (1/64") Radius: The 04 radius is the precision standard. It allows for the finest surface finishes (Ra) and generates the least amount of heat at the tip, ensuring dimensional stability throughout the cut.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH090304-SV | 9.525 mm | 3.18 mm | 0.40 mm |
| Imperial | CPMH321-SV | 3/8" | 1/8" | 0.0157" (1/64") |
Precision Cutting Parameters
*SV geometry performs best at low feeds. For interrupted cuts, maintain speed but decrease feed slightly for edge safety.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless 304/316 | 90 - 170 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.20 mm |
| High Strength Alloy | 70 - 140 m/min | 0.03 - 0.10 mm/r | 0.08 - 1.00 mm |

US735 (Toughness First): Your primary choice for interrupted cuts or when the machine setup is not perfectly rigid.
US7020 (Wear Resistance First): Switch to US7020 for continuous, stable turning at higher speeds to extend tool life when shock is not a factor.

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.
