<p>An indexable drill is offered which enables suitable integration of a drill body and cutting insert. The crosshatch angles of clamp receiving faces of a cutting insert (2) which are respectively pressed by clamp faces and of torque receiving faces which cross the clamp receiving faces and are adjacent thereto and to which is transmitted the rotary force of the drill body (1) from the torque transmission faces are formed smaller within a range of 2° or less which is less than the crosshatch angles of clamp faces which clamp and hold the cutting insert (2) of the drill body (1) and torque transmission faces which cross these clamp faces and are adjacent thereto and which transmit the rotary force of the drill body (1) to the cutting insert (2).</p> |
