<P>PROBLEM TO BE SOLVED: To provide a practical cutting tool having high chipping resistance, by sufficiently reflecting characteristics of a composite fiber in the cutting tool, when applying the composite fiber composed of a composite fiber-like core material having high toughness and a covering layer to the cutting tool. <P>SOLUTION: This cutting tool 1 is composed of a composite structure 15 of randomly arranging a plurality of composite fibers 13 composed of the core material 11 and the covering layer 12 having the composition different from the core material 11 by covering the outer periphery of the core material 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
