PROBLEM TO BE SOLVED: To provide a solid metal circular saw for cutting processes, aimed at preventing occurrence of fusion/seizure due to frictional heat between the cutting blade side face and the cut material, and attaining greatly improved cutting performance. SOLUTION: On the cutting blade side 6 of a solid metal saw composed of cemented carbide as its base material, gradient portions characterized by concave shapes with minor angles and shallow clearance grooves are formed continuously, to constitute a so-called set type blade in which multiple blade edge portions are alternately protruding from the base face 7 of the clearance groove bottom.
