TPMH110302-MV VP15TF
Mitsubishi Materials | Ultra-Precision Miracle Coated Fine-Finishing
Extreme Precision for Small-Radius Finishing
The Mitsubishi TPMH110302-MV VP15TF is a specialized PVD coated carbide insert engineered for high-precision fine finishing. Featuring a sharp 0.2mm corner radius, it minimizes cutting resistance, making it the ideal long-tail precision tool for thin-walled workpieces and tight internal profiles. Utilizing the VP15TF Miracle Coating, this insert provides superior adhesion resistance for CNC boring in Stainless Steels, Alloy Steels, and Mild Steels.

The Miracle PVD Advantage
VP15TF is an AlTiN PVD coating over a micro-grain carbide substrate. This combination allows for a high cutting temperature while protecting the edge from wear. For stainless steel turning, it prevents the material from "welding" to the tip, which is the leading cause of poor surface finish in finishing operations.
MV Multi-Value Chipbreaker
The MV chipbreaker is specialized for stable chip control. In fine finishing, chips are often thin and "stringy." The MV geometry forces these chips to curl and break at low feed rates, protecting the workpiece surface from scratches in high-precision CNC tasks.
