CNMG120408-MS VP15TF
Universal Miracle Grade | PVD VP15TF Coating | MS Chip Control Geometry
Engineered for High-Performance Machining
VP15TF Miracle Grade (The PVD Powerhouse): The VP15TF is Mitsubishi’s most versatile PVD-coated grade. It features a micro-grain carbide substrate with a specialized "Miracle" (Al-Ti-N) coating. This thin, smooth coating allows for a razor-sharp edge, which is critical for reducing cutting resistance and preventing Built-Up Edge (BUE) when machining gummy materials like 304/316 Stainless Steel.
MS Chipbreaker (Precision Control): The MS geometry is a sharp-edged chipbreaker designed for finishing to medium-duty cutting. It features a high rake angle that effectively shears the material, preventing the work-hardening often associated with austenitic stainless steels. It excels at breaking chips into small, manageable "6" shapes even at lower feed rates.
0.8mm (1/32") Universal Radius: The 08 radius provides the ideal balance of edge strength and surface finish quality. It is robust enough for light roughing while sharp enough to achieve high-precision Ra values in finishing passes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120408-MS | 12.7 mm | 4.76 mm | 0.80 mm |
| Imperial | CNMG432-MS | 1/2" | 3/16" | 0.0315" (1/32") |
Precision Cutting Parameters
*The VP15TF grade performs best with high-pressure coolant to manage heat in the cutting zone.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.10 - 0.25 mm/r | 0.50 - 2.50 mm |
| Alloy Steel (4140/4340) | 140 - 220 m/min | 0.12 - 0.30 mm/r | 0.80 - 3.00 mm |

VP15TF vs. US735: Both are great for stainless, but VP15TF offers higher wear resistance for continuous turning. Use US735 if you are performing heavy interrupted cuts where impact toughness is more important than pure sharpness.
MS vs. MA Geometry: Choose MS when chip control is your main issue. The MS geometry breaks chips more aggressively than the MA version.

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.
