MEDICAL DRILL AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A manufacturing method of a medical drill is provided to facilitate mass production by integrally forming a blade on the side of the drill through injection molding. CONSTITUTION: A manufacturing method of a medical drill is constituted as follows. Feedstock including powder is formed. A body unit(110), a blade unit(120), and a side blade unit(121) are formed through injection-molding. An injection-molded body is formed by integrating a side blade unit with the side of a blade unit. Binder is removed from the injection-molded body. A sintered body is obtained by sintering the injection-molded body. The injection-molded body is thermally pressed in order to improve physical property thereof.
