Mitsubishi VCMT110304 VP15TF
Universal PVD Coated Grade for Precision CNC Turning
The Mitsubishi VCMT110304 VP15TF is a highly versatile 35° rhombic positive displacement carbide turning insert. Featuring the legendary VP15TF Miracle Coating, this insert is engineered for the high-performance machining of stainless steel, carbon steel, and heat-resistant alloys. It is the premier choice for machinists requiring a long-life turning insert that prevents built-up edge (BUE) in diverse CNC lathe operations.

Advanced Grade & Chip Control
VP15TF (Miracle Coating): This grade is a PVD-coated micro-grain carbide. The "Miracle Coating" (Al-Ti-N) provides extreme heat resistance and high hardness, allowing for stable cutting even in difficult-to-machine materials like Inconel or 304/316 Stainless Steel.
Universal Chipbreaker: Optimized for finishing and medium-light cutting. The geometry ensures smooth chip evacuation, preventing chip nesting and protecting the surface finish of the workpiece.
Technical Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 80 - 160 m/min | 0.05 - 0.20 mm/rev |
| Carbon/Alloy Steel | 100 - 220 m/min | 0.05 - 0.25 mm/rev |

While VP15TF is the best all-around grade for stainless and light steel cutting, consider US735 if you are performing heavy interrupted cuts in stainless steel. For high-speed finishing of carbon steel in stable conditions, NX2525 cermet may provide a better surface gloss.
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.
