Abstract
A method for manufacturing a throwaway tip is presented in which a green compact Q obtained by press-forming raw material powder for the throwaway tip is placed and sintered on a sintering plate. The green compact Q is press-formed so that the density of the raw material powder is gradually decreased toward a predetermined direction R, and the direction R is oriented substantially toward the outer circumference of the sintering platein plan view. Thus, it is possible to obtain a throwaway tip having sintering accuracy.
