TCMT090202-FM VP15TF
Mitsubishi Materials | Precision Super-Finishing Specialist
The Mitsubishi TCMT090202-FM VP15TF is a world-class PVD coated carbide insert designed for micro-precision super-finishing. By combining the FM chipbreaker (Fine Machining) with the proprietary VP15TF Miracle Coating, this insert achieves incredible chip control at very low depths of cut. It is a critical long-tail precision tool for operators requiring mirror-like surface finishes on carbon steel, alloy steel, and stainless steel workpieces.

VP15TF Miracle Grade
The VP15TF grade is a carbon-rich PVD coating (AlTiN base) known for its high oxidation resistance and extreme surface smoothness. This "Miracle" technology prevents built-up edge (BUE), which is vital when performing super-finishing on gummy materials like stainless steel.
FM Finishing Chipbreaker
The FM chipbreaker is specifically designed for small depth of cut turning. Its unique rake face geometry ensures stable chip evacuation even at extremely low feed rates, preventing "birds-nesting" and ensuring a consistent precision turning experience.

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.
