Size Selection of Rotary File


The selection of rotary file size is mainly based on the head diameter and handle diameter, among which the head blade diameter and total length can be selected according to the specific operation requirements!

Standard rotary file: Handle diameter (D2) mainly 3mm, 6mm, 8mm, 2.35mm optional. The length of the shank is a general specification for operation.

 

Lengthening rotary file: The length of the handle can be selected according to specific working conditions. Generally 75mm, 100mm, 150mm, 300mm, very suitable for processing difficult to contact or deep area, the longer the handle the better. But too long will cause vibration when grinding, affecting the working effect.

Micro rotary file: So the rotary file head diameter is small, the handle diameter is generally 3mm. Because of high concentricity, it is suitable for dressing station parts.
