CCMT120408 VP15TF
The "Miracle" Universal Powerhouse | PVD Coated | 0.8mm Roughing Radius
Material Science & Edge Durability
VP15TF Grade (Miracle PVD Technology): Mitsubishi's most versatile grade. It features an Al-Ti-Cr-N based Miracle Coating that provides industry-leading thermal stability. It is the go-to solution for ISO P (Steel), ISO M (Stainless), and ISO K (Cast Iron). The coating’s extreme adhesion prevents micro-chipping and edge peeling, even during interrupted cuts or dry machining.
0.8mm Radius (High-Efficiency Geometry): The 08 (1/32") radius is designed for maximum metal removal rates (MRR). The larger radius provides a much stronger tip than finishing versions, allowing for aggressive feed rates (fn). This geometry effectively dissipates heat away from the cutting point, extending tool life during heavy semi-finishing of large alloy workpieces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT120408 | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | CCMT432 | 0.500" (1/2") | 0.187" (3/16") | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius thrives under high feed loads. Ensure your machine has adequate horsepower for these parameters.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Alloy Steel (P) | 140 - 260 m/min | 0.15 - 0.35 mm/r | 0.50 - 3.00 mm |
| Stainless (M) | 80 - 170 m/min | 0.12 - 0.25 mm/r | 0.50 - 2.00 mm |

Shop SCLCR 12 HoldersPro-Tip: VP15TF vs UE6110
VP15TF (Miracle Universal): The Versatility Leader. Choose this if you machine a mix of materials. Its PVD coating makes it much tougher for stainless and interrupted cuts.
UE6110 (CVD Steel Grade): Use this only for continuous steel turning at very high speeds. While UE6110 is faster in steel, it will fail quickly in stainless steel due to heat-cracking—whereas **VP15TF** will thrive.

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.
