VP15TF Miracle Grade
The VP15TF grade is a fusion of a high-toughness micro-grain substrate and a specialized PVD Miracle coating. This allows the indexable turning insert to resist built-up edge (BUE) and chipping, making it the primary choice for stainless steel machining and low-to-medium carbon steels.
MA Medium-Cut Breaker
The MA chipbreaker features a geometry optimized for medium cutting applications. It provides excellent chip evacuation across varied feed rates, preventing the workpiece surface from being damaged by continuous chips, especially in gummy materials like SUS304.
Recommended Cutting Parameters
