    • 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.
    • 切削工具具有可滑动的切削刃片5A,其中滑块7可滑动地安装在形成在切削工具主体1中的槽6中,以抵消施加到凹槽6的底面6c的压力, 滑块7,以防止滑块7和凹槽6的磨损以及滑块7和间隔件8的锯齿槽7a和8a的不均匀磨损,并且抑制滑块7的间隙。间隔件9可拆卸地设置在一侧 槽6的表面6a和滑块7,在滑块7的另一侧面和槽6的另一侧面6b之间设置有板22,以将板22朝向侧面6a按压。 突出部21和凹陷部24分别具有V形横截面并分别形成在滑块7的另一侧面和板22的一个侧面上,其中突出部21和凹部 可以相互接触。
