<p>The present invention relates to a drilling tool. The drilling tool according to the present invention is configured such that a diamond-shaped guide pad is arranged in a diamond-shaped pocket, the bottom of which is formed into a V-shape and one side of which has a groove formed therein so as to enable the guide pad to be installed, and a cutting fluid flows between the pocket and the guide pad, thus improving cooling performance of the guide pad. Further, the shape of the guide pad is formed into a shape symmetrical in the left, right, and vertical directions, thus enabling the total four side surfaces to be used and improving economic advantages. In addition, the shape of the guide pad is formed into a diamond shape in a plane view, thus inducing smooth introduction of the cutting fluid. Representative drawing: FIG. 1.</p> |
