Should I choose a medium-tooth file or a fine-tooth file?
Depends on processing requirements and material properties. The following are the characteristics and application scenarios of the two files:
Medium tooth file: high processing efficiency, but slightly poor surface accuracy.
It is suitable for occasions where the processing surface roughness is not high and a large amount of material needs to be removed quickly.
The tooth pitch is large and suitable for roughening the surface of hard materials such as metal and wood.
Fine-tooth file: The surface precision after processing is high, but the processing time is slightly longer.
It is suitable for situations where high surface precision is required and fine trimming is required. Fine-tooth files are more suitable for situations where higher surface precision is required and fine and patient processing is required.
The tooth pitch is small and suitable for fine processing such as deburring, trimming, and grinding on the surface of hard materials such as metal and wood.
Fine-tooth files have a large number of teeth and small spacing. The number of teeth per inch can reach about 100 to 200. When making precision instruments or handicrafts, targeted and detailed grinding is required. Fine-tooth files are particularly important and are suitable for polishing small objects. Processing and finishing of small machinery such as watches, glasses, mobile phones, etc.
The tooth pitch and number of teeth of a medium-tooth file are between fine-tooth files and coarse-tooth files. The number of teeth per inch is between 25 and 100. It is a compromise between fine-tooth files and coarse-tooth files. It can better File off large workpieces while ensuring the flatness and smoothness of the workpiece surface. For example, when making metal products such as automobiles, the surface of the car body needs to be modified to improve the appearance. At this time, an ordinary file becomes one of the necessary tools.
There is no absolute "good" or "bad", and the choice between a medium-tooth file or a fine-tooth file should be determined based on specific job requirements and material characteristics.
