Claims

[Claims for Utility Model Registration] 1. A bracket fixed to the driving main shaft via a socket, and a guide provided on the bracket so as to be slidable in the direction of the central axis and biased by a spring toward the tip of the bracket. A pin, a pair of cutter holders fixed to the mounting surface of the bracket, a cutter fixed to the tip of each of the cutter holders, and a radially outward direction from the tip of the guide pin toward the cutting edges of these cutters. A trepanning tool characterized by being equipped with an oil supply device that forcibly sends air, cutting oil, etc. toward the trepanning tool. 2. The oil supply device is characterized in that air, cutting oil, etc. can be supplied through the insides of the socket, the bracket, and the cutter holder, and further through the insides of the socket, the bracket, and the guide pin. A trepanning tool according to claim 1 of the utility model registration claim. 3 The above cutter consists of an outer cutter and an inner cutter. When cutting the material in an annular shape with these cutters to collect a sampling piece, the outer cutter cuts the outer circumference of the annular groove, and the inner cutter cuts the inner circumference of the annular groove. The trepanning tool according to claim 1 of the utility model registration claim, characterized in that the trepanning tool is made to be able to perform the following functions.
