Deflection of the cartridge body 71 also occurs when the mounting screw 73 is fully tightened. As a result, even if the position of the cutting insert 72 in the radial direction is adjusted, the position of the cutting insert 72 in the radial direction shifts when the mounting screw 73 is fully tightened. Thus, in the cutting tool 200, the accuracy of position adjustment of the cutting insert 72 (cutting edge 72b) is lowered.
  • the radial position of the blade 20 is adjusted by axially advancing and retreating the adjusting piece 40 between the contact surface 10bb and the first blade side surface 22c. Also, the position of the adjustment piece 40 in the axial direction is close to the position of the first mounting screw 30 in the axial direction.
