A tipped saw blade includes a disc-shaped base metal and a plurality of tips. Each tip has an edge selected from a flat edge, a left beveled edge, and a right beveled edge. The tips are positioned circumferentially adjacent each other about a radially outer periphery of the base metal. Each flat edge includes a cutting edge that is oriented parallel to a thickness direction of the base metal. Each left beveled edge and each right beveled edge include a corresponding cutting edge that is inclined with respect to the thickness direction of the base metal. Cutting edge line lengths correspond to the lengths at which the cutting edges come in contact with a workpiece when cutting a workpiece. The cutting edges have the following relationship: (sum of cutting edge line lengths of the plurality of beveled edges)≤[((cutting edge line length of one of the flat edges)−(kerf thickness+1.5))×(number of the plurality of flat edges)×1.2].

A tip saw has disk-shaped and comprises cutting blade pieces, support pieces, and a base metal. The cutting blade pieces are disposed at blade edges of the tip saw. The support pieces are disposed between adjoining two of the cutting blade pieces. The cutting blade pieces and the support pieces are configured to be thicker than a thickness D1 of the base metal of the tip saw (D2>D1). The support pieces have a thickness equal to or nearly equal to the thickness D2 of the cutting blade pieces (D3=D2 or D3≈D2). Consequently, the width of a cut groove Pc formed on a work material by the cutting blade pieces can be maintained wider than the thickness D1 of the base metal of the tip saw by the support pieces without increasing the number of the cutting blade pieces of the tip saw.
