ABSTRACT:
A method for manufacturing a diamond tool having a shank, comprising accurately arranging a diamond chip on an upper surface of a base body in such a manner that the cutting edge of the chip projects from the end of the body by a predetermined distance, provisionally securing the chip to the upper surface of the body by means of an adhesive, fitting the body and an insert having an exposed clayish fixture in a U-shaped channel of a lower die to penetrate and position the cutting edge portion of the chip into the fixture of the insert, passing an upper die against the lower die after the fixture is cured, charging a predetermined amount of powder metals into a vertical hole formed in the upper die, pressurizing the powder metals by a press rod which is inserted in the vertical hole while heating the upper and lower dies in order to sinter the powder metals on the upper surface of the body and in the U-shaped channel of the lower die, thereby to rigidly fix the chip to the body, and shaping the body so as to provide a desired form of a shank.
