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 23 for the throw-away tip 20 has protrusions 25, each of the protrusion includes a sliding contact portion 25a detachably fitted into the inner peripheral groove recessed in the inner peripheral wall of a body. The protrusion 25 has a first tilt portion 25b continuous to the sliding contact portion 25a. In detaching the throw-away tip 20 from the body, the first tilt portion 25b rotates ahead of the sliding contact portion 25a, and a standing portion is elastically deformed due to a wedge effect of the first tilt portion 25b. As a result, the protrusion 25 can be gently removed from the inner peripheral groove 13b.

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 includes plural protrusions 24a formed in a part of an outer peripheral wall 24 of a projecting coupling portion 23. Since the twist angle and a twist direction of the protrusions 24a are set in such a way that with relative rotation when coupling the projecting coupling portion 23 and erected portions 13 together, due to the reaction force received by the protrusions 24a from inner peripheral walls 13a, the projecting coupling portion 23 is pulled to the rear and side of the erected portions 13 and the projecting coupling portion 23 is stably held between the erected portions 13. Since the number of portions that require stringent dimension control and high machining accuracy can be reduced, productivity can be improved.

摘要： In a semi-finishing cutter, rectangular tips and square tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a single cutting edge is formed by a pair of one of the rectangular tips and one of the square tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. A cutting speed of the semi-finishing cutter may be increased and a cutting feed may be made faster, so work in a semi-finishing process may be performed efficiently. The rectangular tips and the square tips have simple shapes, so known commercially available throwaway tips may be used. Accordingly, it is possible to provide the semi-finishing cutter in an easy-to-use form without increasing the cost.

摘要： In a rough cutting cutter, square tips and rectangular tips are disposed in a staggered pattern in an axial direction in second to fourth step portions, so a cutting edge is formed by a pair of one of the square tips and one of the rectangular tips. It is therefore possible to effectively reduce a frequency of contact with a blade root. Furthermore, in the second to a fifth step portions, ARs (rake angles in the axial direction) and RRs (rake angles in a radial direction) of the square tips and the rectangular tips gradually increase in order from a tip end to a back end of a tool body. It is therefore possible to suppress chatter vibration during machining and is possible to reduce roughness of a cut surface of a work material.
