Carbide rotary files, also known as high-speed carbide milling cutters, cemented carbide abrasive milling cutters, etc., are used with high-speed electric grinders or supporting facilities for pneumatic tools. The raw materials of cemented carbide rotary files are generally YG6, YG8, and YG10X. The main purpose of cemented carbide rotary files is widely used in the fields of hardware machinery, cars, shipbuilding, and manual carving.

    The general appearance and relative specifications of the cemented carbide rotary file are as follows: cylindrical, type A; cylindrical with top laser cutting, type B; cylindrical ball cage, type C; spherical type, type D; and its model Specifications Type E, Type F, Type G, Type H, Type L, Type M, Type N, Type T, etc. The main features of cemented carbide rotary files are as follows:

    1. Ability to drill and process various raw materials below HRC70 at will. 2. Pollution of dust-producing environment. 3. High efficiency. 4. Can produce and process various shapes. 5. Long life. 6. The application is simple and convenient. 7. The production cost is reduced. Compared with developed countries, the key difference of cemented carbide rotary files is that everyone's rotary files cannot be sold at a good price, and the quality level is not as good as that of developed countries. Mainly: 1. Raw materials are not as good as French products. 2. The electric welding between the top of the tungsten steel material head and the 45# steel handle is not stable. 3. Excellent CNC lathe processing equipment. 4. The geometrical view angle, tooth profile, and dimensional tolerance precision of the blade. 5. The parallelism of the file.
