Provided is an indexable cutting tool of a lever-lock type applying a greater clamping force than conventional cutting tools. At a bottom of an insert fixing portion (11), there is formed a pillar-shaped lever (3) in a state in which one end (31) protrudes from a placement surface (12) of the insert fixing portion (11). A screw (4) applies a pressing force to the lever (3) between the one end (31) and a portion (32b3) such that the lever (3) is pressed and inclined with the portion (32b3) as a fulcrum in the middle of the lever (3) so that the one end (31) applies a clamping force to the cutting insert (2) . |
