ABSTRACT:
A method for producing a cutting face from a hard cutting material for engineer's tools comprising, essentially, presenting the metal stock to a feed slot within a forming core, heating the same to its deformation temperature and then forcing now deformed stock through said forming core into the desired shape. A helical cutting face produced by such method having a length greater than one-third its total lead; a helix angle in the range of 10.degree.-45.degree.; being of a length of one and one-half inches upward depending upon the particular tool requirement; and being of any desired cross-section.
