摘要： A method for manufacturing drill cutters and structure thereof includes forming a base body by forging that has a shank and a barrel which has a plurality of wedging portions at an upper end and forming a barrel-type drill head through powder metallurgy that has a plurality of coupling elements at a lower end corresponding to the wedging portions. The drill head and the base body can be joined together to form a drill cutter which is wear-resisting and does not fracture easily.
