A method of achieving interchangeability of tool inserts in a quick release chuck mechanism mounted on a drive spindle, the chuck mechanism having a body member with an axial bore extending therethrough, and an end surface transverse to the bore, the tool inert having an end portion insertable in the axial bore, an axial opening in the insert for receiving the tool, and an adjusting screw in the axial opening for adjusting the tool relative to the insert, the tool insert further having an opposite end portion provided with a shoulder facing the end surface and engageable therewith; adjusting means on the end surface of the body member for axial movement for axially varying the position of the end surface relative to the shoulder for achieving a predetermined end surface position; and means for releasably holding the tool insert in the body member with the shoulder in engagement with the end surface adjusting means; the method comprising the steps of adjusting the adjusting means on the end surface of the body member mounted on a complementary spindle to achieve a constant predetermined end surface position of the body member relative to a predetermined reference plane; adjusting the adjusting the screws on a plurality of tool inserts to obtain sharpened tool inserts of identical length from the tip of each tool to each shoulder; and mounting a sharpened tool insert on the body member so that the tip of the tool is a fixed distance from said reference plane, such tool insert adapted, when the tool is dull, to be quickly released by the holding means and replaced by a sharpened tool insert without the necessity of further adjustment of the adjusting means or adjusting screw to maintain said fixed distance between said reference plane and the tip of the tool.
