能な中ぐり工具。[Claims for Utility Model Registration] A tool body that has a fitting hole that extends in the axial direction, is attached to the rotating shaft of a machine tool at the rear, and holds a cutting tool via a cutting tool holding member at the front; and a rear end portion. a rod having a threaded portion on a part of its outer circumferential surface and fitted in the fitting hole so as to be movable in the axial direction but not rotatable; The nut is provided with a female threaded portion that is threadedly engaged with the male threaded portion and has ratchet teeth on the outer circumferential surface, and a pawl that engages with the ratchet teeth, and is movable back and forth in the circumferential direction of the nut. A boring tool capable of adjusting a cutting edge position, comprising: a moving member held in a tool body; and a cutting edge position changing means for changing the cutting edge position of the cutting tool based on movement of the rod, wherein the cutting edge position changing means is configured as described above. a holding hole formed in the tool body extending radially from the fitting hole to reach the cutting tool holding member; a sliding member slidably held in the holding hole; and a front end portion of the rod. an inclined surface formed to be inclined in the axial direction and pushing out the sliding member radially outward as the rod moves in the axial direction, elastically deforming the cutting tool holding member and changing the position of the cutting edge of the cutting tool; A boring tool with an adjustable cutting edge.
