The borach is comprised of a support mandrel and a plurality of broach plates stacked on the mandrel and angularly referenced thereto, each of the broach plates having a peripheral surface shaped at least in part to form a cutting edge to define at least part of the desired bone opening for the respective axial position of that broach plate on the mandrel.
