  • Publication number: 20200222992
    Abstract: A drill is a long drill that is provided with a discharge groove having a helix angle of 25 degrees, in which a groove length is 30D or more. Thinning processing is performed on a leading end portion of the drill and a gash portion that is connected to the discharge groove further to an inner side in the radial direction than an outer peripheral surface. A circular arc groove is formed in a section connecting a thinning face and a gash face, and a chip discharge performance is improved. When forming a deep hole, in a guide hole forming process, a guide hole with an inner diameter d of D+0.03 mm or less and with a depth W of 3D or more, is formed (S2 to S6). In an insertion process, the drill is rotated in a reverse direction and is inserted into the guide hole to a position just before a bottom portion of the guide hole (S11 to S13).
