Abstract
A cutting tool may include a holder extended along a central axis from a first end to a second end and including a pocket, and a cutting insert located in the pocket. The holder may further include an upper surface, a lower surface, a first end surface, a first side surface, a recess, a first flow path and a second flow path. The recess opens into the first end surface and the first side surface. The first flow path is located along the central axis. The second flow path is located closer to the upper surface than the recess and connects to the first flow path. An imaginary plane that passes through the central axis and is orthogonal to the lower surface is a reference plane. The pocket opens into the recess and is recessed from the recess toward the reference plane.
