TPMH160302-FV VP15TF
Mitsubishi Materials | Large-Scale Precision Super-Finishing Specialist
Mastering Mirror Finishes in Heavy-Duty Boring
The Mitsubishi TPMH160302-FV VP15TF is a unique PVD coated carbide insert engineered for ultra-fine finishing. While the TPMH16 size is typically for heavy work, the 0.2mm corner radius and FV (Fine-Finish) chipbreaker allow for extreme precision on large-diameter components. Featuring the legendary VP15TF Miracle Coating, this long-tail super-finishing tool provides the thermal stability needed for CNC boring of Stainless Steels, Alloy Steels, and Heat Resistant Superalloys.

VP15TF Miracle PVD Grade
VP15TF is Mitsubishi’s proprietary multi-layer PVD coating. It is designed to withstand the high temperatures of super-finishing without losing edge sharpness. Unlike CVD coatings, which can be too thick for ultra-sharp radii, this PVD Miracle Coating adheres perfectly to the 0.2mm tip, preventing peeling and ensuring long tool life.
FV "Fine-Value" Geometry
The FV chipbreaker is an ultra-positive geometry designed to slice through material with minimal cutting resistance. This is critical for the 0.2mm radius version to prevent "rubbing" and work-hardening of the workpiece surface, especially in sensitive materials like 304/316 Stainless Steel.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
