Abstract
Embodiments of a reamer of the present invention generally include a substantially tubular body sub, a substantially planar base plate having one or more receiving cavities disposed therein, one or more gussets, a fluid chamber, and a plurality of leg/cone assemblies having a leg end and a cone end; wherein the base plate is disposed around the body sub and stabilized by the gussets, and each leg end comprises an exterior surface geometry complementary to the interior surface geometry of a base plate receiving cavity and is insertable into and affixable therein. The receiving cavities are constructed in defined locations and orientations in the base plate and the leg/cone assemblies are precisely formed such that insertion of the leg end into the receiving cavity accurately and precisely disposes the cutting component about the reamer. Embodiments of methods of providing and using an apparatus of the present invention are also provided.
