Abstract

A cutting tool assembly includes: a tool body extending in a longitudinal direction; a lower jaw extending and protruding forward from the tool body; a clamping portion disposed to be spaced apart from a top surface of the tool body; an upper jaw extending forward from the clamping portion and facing the lower jaw; an elastic connecting portion elastically connecting the tool body and the clamping portion to each other on a rear side of the clamping portion; a clamping screw penetrating the clamping portion downwardly and fastened to the tool body; and an upper coolant channel through which coolant flows, the upper coolant channel penetrating the elastic connection part, the clamping portion, and the upper jaw. In a width direction perpendicular to the longitudinal direction, a width of the clamping portion is in a range of 40% to 80% of a width of the tool body.
