A temporary coupling mechanism facilitates replacement of a cutting tip in a pocket of a cutting tool, by preventing the cutting tip from falling out of the pocket when a clamping member, e.g., a screw member or wedge member, is loosened. The pocket is provided with a first coupling portion and the cutting tip is provided with a second coupling portion configured to engage the first coupling portion. In one embodiment, the second coupling portion is at least one concave groove or convex portion located in a predetermined position of the cutting tip. A convex portion or a concave groove is provided in at least one of the pocket's tip mounting seat and the clamping member to engage the concave groove and the convex portion of the cutting tip. The concave groove extends substantially in parallel with the seat face of the tip mounting seat and the convex portion is inserted and fitted into the concave groove so as to be engaged thereto when the cutting tip is inserted into the tip mounting seat and is taken out of the tip mounting seat, causing the cutting tip to be movable only in a predetermined direction relative to the tip mounting seat.
