る穴あけ工具。[Claims for Utility Model Registration] A drilling tool in which a center drill 4, a diameter expanding blade 5, and a guide pad 6 are respectively attached to a cutting head 3 of a cylindrical holder 1, the center drill 4 The amount of protrusion in the axial direction can be adjusted by an adjustment screw 8 located at the rear end, and the blade 5 is composed of a pair and is arranged in a receiving seat 10. At this time, the cutting edge nap 13 forming the inclined cutting edge ridge 12 that participates in conical cutting is in a relationship such that it is offset in the radial direction and axial direction on its rotation locus and performs the cutting. Furthermore, the guide pads 6 are composed of a pair and are arranged so as to approach the rear of the blade 5 in the direction of rotation, corresponding to the chip pockets 16 that are provided next to each other when the blade is attached.
