Abstract
A boring tool includes a concave groove formed on the outer peripheral surface of a tool body on the side opposite from a cutting blade with respect to an axis of the tool body. The concave, groove 10 is formed so as to extend from a position x, which is separated rearwardly from a front end face of a head portion, toward the rear side, and to be open downward from above a rake face. Furthermore, a sub-groove is formed between the concave groove and a chip pocket. Accordingly, the natural frequency is increased by reducing the weight of the head portion while limiting rigidity reduction, thereby restricting chattering.
