Abstract: A circular saw blade includes a disc-shaped base metal having an outer diameter of 200 mm to 500 mm, and a plurality of first tips, and a plurality of second tips alternately arranged along an outer circumference of the base metal. The circular saw blade has a blade thickness about 0.8 mm to 2.0 mm. The first tips and the second tips have cutting edges and a pair of chamfers at both ends of the cutting edges. A first groove and a second groove are formed in a flank so as to extend in a circumferential direction of the cutting edges. The first groove includes a first groove bottom that is deepest in a radial direction at a position of a first distance from a thickness center in a first thickness direction. The second groove has a second groove bottom that is deepest in the radial direction at a position of a second distance from the thickness center in a second thickness direction opposite to the first thickness direction. A sum of the first distance and the second distance is about 0.35 mm or less.
