Abstract
A cutting tool is constituted by plural faces and a tip portion structured with edges of the plural faces, wherein groove is formed on at least one of the plural faces. The groove is grid pattern and a dent portion is formed at some intersections of the grid pattern. Furthermore, a space is secured between one of ends of the groove and an edge constituted by a cutting face and a flank face. There is thus provided a cutting tool and a cutting machine capable of supplying cutting fluid to a tip of the tool or to a working point at the tip of it surely with simple structure.
