A drill body 1 is provided with a flange portion 3 located on the intermediate portion side, respectively, and an eccentric sleeve 17 that is fitted at the mounting shaft portion 4 of the drill body 1.
and the drill body 1 via this eccentric sleeve 17.
The eccentric sleeve 1
In this drilling tool, the drill body 1 has a finishing edge 1 for diameter expansion on the intermediate portion side behind the tip cutting edge 14.
5, and the annular surface of the flange portion 3 in contact with the eccentric sleeve 17 is provided with a receiving hole 31 for receiving a pin 28 protruding from the annular surface 20 of the tool head 18. The eccentric sleeve 17 consists of a flange portion 22 and a fitting shaft 23, and the flange portion 22
is located between the flange portion 3 of the drill body 1 and the tool head 18, and the annular surface thereof has a mounting hole that is elongated in the circumferential direction so that the mounting screw 19 and pin 28 can be inserted therethrough and rotated. 27 and a guide hole 29 are bored, and the outer circumferential portion 25 of the fitting shaft 23 fits into the inner circumferential portion of the tool head 18.
The inner circumferential portion 24 of the fitting shaft 23 is eccentric with respect to the outer circumferential portion 25 so as to fit into the mounting shaft portion 4 of the drill body 1, and the tool head 18 is attached to the inner circumferential portion. The outer peripheral portion 25 of the eccentric sleeve 17 is fitted into the annular surface 20, and a screw hole 21 for the mounting screw 19 is bored in the annular surface 20, and a pin 28 is provided in a protruding manner. A drilling tool characterized in that it is positioned from a guide hole 29 of a sleeve 17 into a receiving hole 31 drilled in a flange portion 3 of a drill body 1.
