How to check if the saw blade of a circular saw is shaky during cutting?
Follow me and learn a trick! If you feel the surface of the iron is smooth without any grooves, and the iron shavings are of this shape,
it means the saw blade is in the correct position and the cutting process is stable.
On the other hand, if the saw blade is shaky, the iron shavings will be of irregular and strange shapes.
If the cutting is not straight, you will feel grooves on the surface of the iron.
