[0002] A milling cutter is a rotary tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in sequence. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0004] The problem with the prior art is that when a milling cutter is used to process holes of different diameters, since the holes of different diameters are composed of holes of different sizes, the milling cutter needs to be replaced during processing. However, the current milling cutter needs to be manually locked through a locking nut by matching the corresponding retaining spring. When processing holes of different diameters, the locking nut needs to be manually locked multiple times to replace the milling cutter, which increases the working time. After processing the holes of different diameters, the milling cutter is generally exposed to the outside after being placed, so it is easy to accumulate dust. Therefore, we propose a composite milling cutter for processing holes of different diameters. Utility Model Content
