Is a Vibrating Table Saw Blade Giving a High Pitched Sound a Concern for Shop Safety
posted on by

Q: I have a 12"-diameter table saw blade that “sings” every time I turn on the saw. The longer the saw runs, the higher the pitch gets. I haven’t run a board through the saw because I’m not sure if this blade is safe.

A: Saw blades can have excessive vibrations or “sing” for many reasons. Usually, it is an indication that a blade has lost its tensioning. As for the safety of the blade, we would not recommend using any blade that is in less than perfect condition. Safety should be your principal concern.
