Abstract
A circular saw including an annular disk-shaped base adapted to be driven about an axis of rotation, a plurality of tip supports formed along the outer circumference of the base integrally therewith so that a gullet is defined between adjacent ones of the tip supports, a plurality of tip inserts respectively fixed to the tip supports, a plurality of openings formed through the base on substantially the same circumference of a circle so as to be equally spaced apart from each other in the circumferential direction of the base, and a plurality of wiper tips respectively fixed to wall surfaces defining the openings on the downstream side of a rotational direction of the base. Each wiper tip has a front surface formed as a concave surface in cross section.
