Abstract
A cutting tool assembly includes a tool shank having a coupling opening, and an insert holder having an insert body to which an insert is coupled and detachably attached. A coupling protrusion protrudes from one surface of the insert body and is detachably coupled to the tool shank. Located on the coupling protrusion are a tapered contact portion which comes into contact with the coupling opening and provides a fixing force to fix the insert holder to the tool shank, and a contact surface at a rear end of the tapered contact portion which couples to a fastening member.
