Like I understand the concept of kickback but why cant we reverse the direction of the teeth so it kicks forward and binds the blade.
In: Engineering
Kickback happens when the blade binds and the force (of rapidly slowing the blade and motor) either goes into the workpiece (table saw) or tool (circular saw).
If we turned the blade the other way circular saws would try to climb out of the cut and rocket off across the workpiece (see circular saw races). Additionally, if the blade rotated into the work you have to always hold the saw back from cutting deeper. As they are in use now, the force of cutting pulls the shoe of the saw into the workpiece, and if you stop pushing the saw doesn’t keep feeding.
A table saw blade turning in the direction of the cut would tent to pull in the workpiece and potentially the operator – not great.
