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
