Feature 1Mill Cutter, usually used to be assembled on milling machine. 2Suitable for CNC data processing center, carved, high-speed machines. 3Can milling of copper, aluminum, tool steel, cast iron, etc. 4High toughness, abrasion resistance, high-speed cutting for the high hardness. 5Can processing directly or fine processing to the heat treatment mold.Features: Mill Cutter, usually used to be assembled on milling machine. Suitable for CNC data processing center, carved, high-speed machines. Can milling of copper, aluminum, tool steel, cast iron, etc. High toughness, abrasion resistance, high-speed cutting for the high hardness. Can processing directly or fine processing to the heat treatment mold. Reducing the number of tool changes, improve machine actuator movement rhythm, save mold making time.
