ABSTRACT:
A cutting tool has a slidable cutting-blade chip 5A, in which a slider 7 is slidably mounted into a groove 6 formed in the cutting tool main body 1, to offset a pressing force applied to the bottom face 6c of the groove 6 through the slider 7, to prevent abrasion of the slider 7 and the groove 6 and uneven abrasion of serration grooves 7a and 8a of the slider 7 and a spacer 8, and to suppress backlash of the slider 7. A spacer 9 is detachably disposed between one side face 6a of a groove 6 and a slider 7, a plate 22 is disposed between another side face of the slider 7 and another side face 6b of the groove 6 so as to press the plate 22 toward the side face 6a. A protruding section 21 and a dent section 24 each have a V-shape cross-section and are formed on another side face of the slider 7 and on one side face of the plate 22, respectively, wherein the protruding section 21 and the dent section can come into contact with each other.
