VP15TF Miracles Grade
The VP15TF grade combines a micro-grain carbide substrate with Mitsubishi's exclusive Miracle (AlTiN) PVD coating. This grade is optimized for stable machining across a vast range of workpieces. It prevents built-up edge (BUE) and offers superior heat resistance during high-speed lathe turning.
FS Chipbreaker Geometry
The FS chipbreaker is an ultra-high positive finisher. Designed for minimal cutting resistance, it excels at breaking chips at low feed rates. This ensures that CNC boring operations maintain tight tolerances without the risk of "bird-nesting" chips marring the surface finish.
