TPMH090208-MV VP15TF
Mitsubishi Materials | High-Durability Miracle Coated Carbide
Edge Strength for Demanding Boring Tasks
The Mitsubishi TPMH090208-MV VP15TF is a high-toughness PVD coated carbide insert. Featuring the legendary Miracle Coating (Al-Ti-N), this grade provides extreme heat resistance and prevents edge chipping. With an 0.8mm corner radius, this long-tail versatile insert offers significantly higher feed capabilities and edge durability than smaller radius variants, making it the ideal choice for CNC boring in Stainless Steels and Alloy Steels where tool pressure is a factor.

Miracle PVD Grade VP15TF
The VP15TF grade combines a micro-grain carbide substrate with an Al-Ti-N PVD coating. This provides a "tough-hard" surface that prevents Built-Up Edge (BUE). It is particularly effective for stainless steel turning where material adhesion is the primary cause of tool failure.
MV Multi-Value Chipbreaker
The MV chipbreaker is designed for stability. While finishing chipbreakers can be brittle, the MV design handles depth of cut variations gracefully. Combined with the 0.8mm radius, it allows for high-efficiency machining in rough-to-finish operations.
