Mini word milling cutter features and cutting purposes are as follows:

1. Features:
   Multi-edge cutting: Mini word milling cutters usually have multiple teeth, which can carry out multiple cutting processes at the same time, thereby improving processing efficiency. At the same time, multi-tooth cutting can reduce the load of each tool tooth, improve cutting stability, and reduce the friction and heat between the tool and the workpiece.
   High efficiency: Mini word milling cutter has the characteristics of high speed and high processing efficiency, and can complete a large number of cutting work in a short time, which is suitable for large-scale production.
   Strong variability: Mini word milling cutter can perform different cutting operations according to the processing requirements of the workpiece, with high flexibility and adaptability.
   High precision: Mini word milling cutter can ensure high precision in the processing process, suitable for high machining accuracy requirements.

2, cutting purposes:
Mini word milling cutter is mainly used for cutting metal, non-metal and composite materials.
In the field of metal working, mini word milling cutters can be used to cut aluminum, copper, stainless steel and other materials, suitable for cutting and milling operations of various shapes.
In the field of non-metallic processing, mini word milling cutters can be used to cut plastics, wood, rubber and other materials for a variety of engraving and cutting operations.
In the field of composite material processing, mini word milling cutter can be used to cut carbon fiber, glass fiber and other composite materials, suitable for aviation, automotive and other industries manufacturing and processing.

In short, mini word milling cutters have the characteristics of multi-edge cutting, high efficiency, high variability and high precision, and are suitable for cutting and milling operations of various metals, non-metals and composite materials.
