摘要： A throw-away rotating tool includes at least two grooved portions 13b, 13c formed on each of erected portions 13 and at least two protrusions 26, 27 for fitting into and removal from respective grooved portions 13b, 13c and projected from a projecting coupling portion 23, and the grooved portions 13b, 13c are formed asymmetrically about an axis O and the protrusions 26, 27 are formed asymmetrically about the axis. Thus, the direction in which the projecting coupling portion 23 can be coupled to the erected portions 13 is uniquely determined. Consequently, variations in lip height and run-out can be minimized. As a result, occurrence of a bend and an increase in machined hole diameter during drilling can be prevented, thereby making it possible to minimize variations in machining accuracy and tool life.

摘要： A throw-away rotating tool includes plural protrusions formed in a part of an outer peripheral wall of a projecting coupling portion. Since the twist angle and a twist direction of the protrusions are set in such a way that with relative rotation when coupling the projecting coupling portion and erected portions together, due to the reaction force received by the protrusions from inner peripheral walls, the projecting coupling portion is pulled to the rear and side of the erected portions and the projecting coupling portion is stably held between the erected portions. Since the number of portions that require stringent dimension control and high machining accuracy can be reduced, productivity can be improved.

摘要： A throw-away rotating tool improves workability of detaching a throw-away tip and prevents from damaging a body. In the throw-away tool, a convex connection for the throw-away tip has protrusions, each of the protrusion includes a sliding contact portion detachably fitted into the inner peripheral groove recessed in the inner peripheral wall of a body. The protrusion has a first tilt portion continuous to the sliding contact portion. In detaching the throw-away tip from the body, the first tilt portion rotates ahead of the sliding contact portion, and a standing portion is elastically deformed due to a wedge effect of the first tilt portion. As a result, the protrusion can be gently removed from the inner peripheral groove.
