Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rotary cutting tool capable of improving wear resistance in the case where a material to be cut is cut. SOLUTION: In a circular saw 10 as a rotary cutting tool a ring shaped coating layer 16 formed by, for example, high speed flame spraying is provided on both side faces of a main body 17. The coating layer 16 is formed in a range (the range indicated by slant lines in the figure 1) from an inner peripheral circle L1 to the edge 12b of a blade 12, being a range containing a position wherein at least wear is most feared in the main body 17.
