The insert attachment mechanism includes an adjustment member (30) and a wedge member (10). The adjustment member (30) is arranged on an inner side of the cutting inset so as to act on the cutting insert in the insert attachment part. The adjustment member is advanceable and retractable in a direction of the central axis of a screw member (40) by rotating the screw member. The wedge member and the cutting insert are arranged on the outer side of the adjustment member in the insert attachment part and exert a pressing force against the cutting insert and an inner wall surface of the insert attachment part. The wedge member (10) is configured such that the screw member (40) is accessible from the outer side of the wedge member.
