General description Mill Cutter, usually used to be assembled on milling machines. It is suitable for carved, high-speed machines and can mill materials such as copper, aluminum, tool steel, and cast iron. With high toughness and abrasion resistance, it allows for high-speed cutting of high hardness materials. This tool can be used for direct processing or fine processing of heat treatment molds, reducing the number of tool changes and improving machine actuator movement rhythm, ultimately saving mold-making time.
