A broaching apparatus includes a first tooth having a front face, a rear face opposite the front face, and a first cutting surface have a lobed shape extending along a first side of the first tooth between the front face and the rear face. A first interface defined between the first cutting surface and the front face is offset relative to a second interface defined between the first cutting surface and the rear face in a direction that is substantially perpendicular to an axis of tooth movement for broaching operations to provide tool clearance rearward from the first interface. A method of making a broach cutter is further provided.
