A cut waste discharging device for a circular saw blade of an electric power circular saw machine, which includes: a safety cover for covering an upper portion of the circular saw blade; a lower guard which is angularly movable into the safety cover in accordance with development of a cutting operation of a workpiece with the circular saw blade; and a partition wall provided along an inner peripheral wall of the safety cover so as not to interfere with the lower guard, thereby defining a passage of cut waste with the outer wall of the partition wall and the inner peripheral wall of the safety cover. With such an arrangement, the passage between the outer wall of the partition and the inner wall of the safety cover causes the cut waste, generated in the waste generating portion, to be led to a predetermined discharge place. Accordingly, the waste would not be splash within the safety cover and would not be splashed out of the predetermined discharge place.

Cover structure for electric circular saw

A table saw has a circular saw table, a miter table and a supplementary table to form a working table, on the front and rear sides of which two guide rails are disposed slidably with respect to the working table. The miter table has a miter fence thereon whose pivot points are provided at two separate positions.
