VP15TF Miracle Coating
VP15TF is Mitsubishi’s proprietary PVD coating. It features a micro-grain carbide substrate for maximum toughness and a Miracle (Al-Ti-N) coating that resists oxidation at high temperatures. This makes it a long-tool-life turning insert for mixed-material production shops.
FV Precision Chipbreaker
The FV chipbreaker is designed for finishing at low feed rates. Its sharp, positive geometry reduces cutting resistance, which prevents workpiece deflection and chatter. This is vital for achieving tight tolerances and mirror-like finishes in internal boring cycles.
