Summary:To provide a cutting tool capable of tightly fixing a cutting insert.SOLUTION: There is provided a cutting tool capable of loading a replaceable cutting insert having a bore for fixation. The cutting tool comprises a body part, lever, pin and screw. The body part has: a placing face on which the cutting insert is placed; a side wall in contact with at least one side of the cutting insert; a lever storage hole; a pin storage hole; and a screw storage hole. The screw presses the rear end part of a pin by tightening, and the tip of the pin presses the lever by the rear end part of the pin pressed by the screw. The lever has a concavity configured by a line segment parallel to a reference axis, and when the concavity is pressed against the tip, a head part extruding in the bore of the placed cutting insert presses a bore inner wall and presses the cutting insert against the placing face and side wall to immobilize.SELECTED DRAWING: Figure 7 【課題】切削インサートを強固に固定できる切削工具を提供する。【解決手段】固定用の穿孔を有する交換式の切削インサートを装着可能な切削工具であって、本体部と、レバーと、ピンと、ねじとを備え、本体部は、切削インサートが載置される載置面と、切削インサートの少なくとも一側面と接する側壁と、レバー収容孔と、ピン収容孔と、ねじ収容孔とを有し、ねじは、締め付けられることによりピンの後端部を押圧し、ピンは、後端部がねじに押圧されることにより先端部がレバーを押圧し、レバーは、基準軸に平行な線分によって構成される凹面を有し、凹面がピンの先端部に押圧されることにより、載置された切削インサートの穿孔に突出する頭部が穿孔の内壁を押圧して切削インサートを載置面と側壁へ押し当てて固定する。【選択図】図7
