ABSTRACT:
A method for manufacturing a throw-away hob includes the steps of cutting screw threads on a threaded body at equally spaced intervals in the circumferential direction of the body and continuously in the axial direction thereof so as to form a throw-away hob body having a plurality of adjacent unit screw threads formed at equally spaced intervals in the circumferential direction of the hob body and in plurality of rows disposed in the axial direction thereof, allowing the threaded side surfaces of a plurality of axially aligned unit screw threads to be subjected to electrical discharge machining so as to form throw-away tip mounting seat surfaces thereat; and fixedly securing a throw-away tip to each of the seat surfaces thus formed.
