Mitsubishi Materials | Precision Miracle PVD Fine-Finishing Specialist
Extreme Precision for Small Diameter Profiling
The Mitsubishi VCMT110302-FM VP15TF is a 35° diamond PVD coated carbide insert designed for high-accuracy finishing. Featuring the Miracle Coating (VP15TF), it offers unparalleled resistance to thermal cracking and oxidation. The sharp 0.2mm corner radius and 7° relief angle make it the best finishing insert for internal boring and intricate external profiling where minimizing tool pressure and preventing chatter is critical.

VP15TF Miracle PVD Grade
The VP15TF Miracle Coating is an Al-Ti-N based PVD coating that creates an extremely hard surface while maintaining core toughness. This grade is the long-tail choice for small CNC lathes because it allows for stable cutting across a massive material spectrum, including carbon steel, stainless steel, and cast iron, without sacrificing surface finish quality.
FM Chipbreaker Optimization
The FM (Finishing-Medium) chipbreaker is specifically designed for low-depth finishing passes. In precision boring, long stringy chips are a major risk; the FM breaker ensures consistent chip curling and breaking even at feed rates as low as 0.03 mm/rev, protecting the finished internal bore.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Stainless Steel (304/316) | 60 - 160 m/min | 0.03 - 0.12 mm/rev | 0.1 - 1.0 mm |
| Alloy Steel (4140) | 100 - 220 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.2 mm |

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.
