ABSTRACT:
A sawing machine having an angle indicator has a worktable, a pivot shaft, a saw blade holder fastened to the pivot shaft as the pivoting center thereof and having a motor, and a saw blade connected to the saw blade holder, rotatable by the motor and passing through the worktable. The angle indicator has an angle indicating member having an index zone and a following member. The following member is fixed on the pivot shaft and connected to the angle indicating member. Thereby the saw blade is moved with the saw blade holder, and the following member is pivoted with the saw blade holder by the pivot shaft to result in movement of the index zone when the saw blade holder pivots, so that the displacement of the index zone corresponds to the movement of the saw blade.
