Abstract
An indexable cutting tool stably clamps cutting inserts and prevents contact between head parts of fasteners and workpieces. Recesses with a bottom are formed in an upper surface of a cutting insert. Part of an inner wall surface of each recess curves and bulges toward a center axis of the recess. The recess is divided into first to fourth regions by a first imaginary reference plane parallel to a rotation axis of a body, and a second imaginary reference plane perpendicular to the rotation axis. The second region is on a center side and on a proximal side of the body. A tapered surface of a fastener contacts the curved surface within the second region. A center axis of the fastener inclines so a head part opposite a distal end part is closer to the center side and to the proximal side of the body than the distal end part.
