装置。[Claims for Utility Model Registration] 1. A pilot bar is attached to a feed frame that is provided with a cutting tool and is movable forward and backward, and is movable relative to the feed frame within a certain stroke in the moving direction of the feed frame and within a certain range in the radial direction. A jig plate for guiding the cutting is attached to the front end of the pilot bar, and the jig plate includes a tool guide section for guiding the cutting tool, and a jig plate for guiding the cutting tool. A mandrel is provided that fits into the machining reference hole to position the jig plate. When the mandrel is fitted into the machining reference hole, the feed frame moves independently; otherwise, the feed frame and pilot bar move together. In a cutting device configured such that the feed frame and the pilot bar move together, a restraint is provided at the pilot bar insertion portion of the feed frame to restrain the pilot bar from the outer circumferential side and suppress radial movement when the feed frame and the pilot bar move together. A cutting device characterized in that it is provided with a pilot bar support means that operates by switching between a state and a release state in which the pilot bar is released when the feed frame moves independently. 2. The pilot bar support means is configured such that both the pilot bar and the feed frame are provided with tapered surfaces that fit together when the feed frame and the pilot bar move together and separate in the axial direction when the feed frame moves independently. The cutting device according to claim 1, characterized in that: 3 Elastically expands and contracts in the radial direction using hydraulic pressure,
2. The cutting device according to claim 1, wherein the pilot bar supporting means is constituted by a chuck member that can switch between a restrained state in which the pilot bar is restrained from the outer circumferential side and a released state in which the restraint is released.
