摘要： A cutting tool (10) with through coolant has an elongated shank (11) and a cutting portion (12). An outer peripheral surface of the shank (11) is configured to be surrounded and tightly held by a hole-wall defined by a tool-fixing hole (921) of a machine tool (92). At least one coolant-guiding recess (111) is formed in the outer peripheral surface of the shank (11) and extends along a lengthwise direction of the shank (11). Each coolant-guiding recess (111) forms a coolant channel (112) together with the tool-fixing hole (921). An end of the coolant channel (112) is connected to a coolant-supply system (922). The coolant channel formed by the coolant-guiding recess (111) enables coolant from the coolant-supply system (922) to be jetted toward the cutting portion (12). The cutting tool (10) provides through coolant without drilled holes, thereby saving cost.
