To provide a tool holder capable of accurately and surely correcting the lean of a blade tip of a tool even if the matching position of an eccentric cam relative to the angle position at which the lean of the blade tip becomes the maximum is displaced when correcting the lean of the blade tip of the cutting tool.
The tool holder configured to correct the lean of the blade tip of a tool includes: a ring member 16 rotatably fitted in a coupling base 14a of an arbor 14 with a flange 13; a stopper member 17 holding the ring member 16 in the coupling base 14a; a main blade tip lean correcting mechanism 20 provided in the ring member 16 to elastically deform the coupling base 14a of the arbor 14 in the radial direction so that the lean of the blade tip of the tool 29 approaches zero; and first and second fine adjusting blade tip lean correcting mechanisms 21 and 22 provided at the ring member 16 around the main blade tip lean correcting mechanism 22 at a certain interval in the circumferential direction of the ring member 16 to elastically deform the coupling base 14a of the arbor 14 in the radial direction so that the lean of the blade tip of the tool 29 approaches zero.
