VP10RT Miracle Grade
The VP10RT grade is a high-hardness Miracle PVD coated carbide. Compared to VP20RT, it offers significantly higher wear resistance and edge stability, making it ideal for stable, continuous cutting at higher speeds in steel and alloy steels.
GM Chipbreaker Geometry
The GM (General Machining) chipbreaker is designed for balanced performance. It excels in diverse grooving depths, ensuring stable chip breaking into manageable "6" or "C" shapes, which is critical for preventing long chip entanglements in CNC lathe processes.
