A tool having an interchangeable insert includes a body with a recess for receiving the insert. The body is further provided with alignment means whereby the insert and body may be operatively positioned with respect to a work piece. A wedge positioned between the insert and the body forces the insert into operational contact with the alignment means. A step abuts a portion of the edge so as to force the wedge against the insert in substantial line contact therewith so as to prevent opposite surfaces of the body and insert from fully contacting the wedge in a manner which could result in frictional blocking, i.e. taper lock, and accordingly subsequent improper hang up of the wedge.
