）。[Scope of Claim for Utility Model Registration] (1) A rough-finished part with a plurality of cutting blades arranged on the outer diameter upward in the longitudinal direction, and a plurality of cutting blades that continue from the rough-finished part and cut in the tooth thickness direction. In a broach for machining internal gears consisting of a finishing blade part, the rough finishing part has a diameter D of the hakama smaller than the involute generation diameter DF.
A small diameter cutting edge that cuts C is formed, and in the finishing edge part, the small diameter D of the broach is changed from the involute generation diameter DF.
A broach for machining internal gears, characterized in that a chamfered edge extending outward toward R is formed. (2) The diameter of the cutting edge on the small diameter side is DC≦DF−
A broach for machining internal gears as described in Claim 1 of the Utility Model Registration Claim, which has a diameter of 0.2 mm (where DC: the diameter of the hook, and DF: the diameter at which the involute occurs).
