Abstract: 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.
