VP15TF Grade Advantage
The VP15TF Miracle Grade is a high-toughness carbide substrate combined with a high-adhesion PVD coating. It excels at preventing built-up edge (BUE) and notch wear, making it extremely reliable for medium-speed machining of austenitic stainless steels and alloy steels.
U2 Chipbreaker Profile
The U2 chipbreaker is specialized for copying and profiling. It features a unique rake angle designed to facilitate stable chip breaking even at varying depths of cut, reducing the risk of "bird-nesting" chips during CNC lathe operations.
Recommended Cutting Parameters
