VP15TF PVD Carbide
The VP15TF grade features Mitsubishi’s Miracle (AlTiN) PVD coating. This grade is optimized for general-purpose lathe turning because of its high resistance to welding and chipping. It is especially effective for stable machining of difficult materials like stainless steel and small-diameter boring where heat buildup is a factor.
FS "Super-Finish" Breaker
The FS chipbreaker is designed with a high-positive rake for super-finishing. It excels at breaking chips at low feed rates and shallow depths of cut, ensuring chip evacuation is smooth and surface finish remains flawless without the risk of scratching the workpiece.
