Abstract

A broaching tool is described having an elongated tool body 20 with an arcuate face of preferably half-round configuration. A plurality of recesses are formed on the arcuate face, each having a flat bottom face 26 inclined inwardly and rearwardly within 1-15 DEG of coincidence with the longitudinal axis of the body and an arcuate abutment wall 27 perpendicular to and rearwardly surrounding the flat bottom face 26. These recesses are arranged in helical paths of increasing diameter in a rearward direction to form a series of spaced helical rows. Each recess contains a rotatably indexable cylindrical cutter disc 24. This configuration of broach has the advantages of providing excellent chip clearance between the cutter and also providing a uniform load on the tool during broaching. <IMAGE>
