Abstract
A cutting tool may include a main body having a bar shape extended along a central axis. The main body may include a cutting edge, a first flow path, a second flow path, a third flow and a fourth flow path. The first flow path is located along the central axis and may include an inflow port. The second flow path is located along the central axis and may include a smaller inner diameter than the first flow path. The third flow path may connect to the first flow path and may include a first outflow port. The fourth flow path may connect to the second flow path and may include a second outflow port. The first outflow port is located more away from an imaginary plane including the central axis and the cutting edge than the second outflow port.
