Rotary file size selection:

The size of the rotary file is mainly based on the head diameter Dc and the handle diameter D2. The head blade diameter L2 and the total length L1 can be selected according to the specific operation requirements.


Standard type rotary file: The shank diameter (D2) mainly has 3mm, 6mm, 8mm, and 2.35mm is also optional. The length of the handle is a common specification for operations.


Extended shank rotary file: This kind of shank length can be selected according to the specific working conditions to extend the shank, generally 75mm, 100mm, 150mm, 300mm are commonly used. It is very suitable for processing hard-to-reach or deep areas. The longer the handle of the extended handle, the better, because too long will cause vibration during the grinding operation and affect the operation effect.


Miniature rotary file: Therefore, the diameter of the head of this kind of rotary file is small, and the diameter of the shank is generally 3mm. Because of its high concentricity, it is suitable for the trimming of station parts.
