Beschreibung
Zusammenfassung:	One aspect of the invention provides an injection-molded reamer including: an injection-molding parting line; and one or more shafts having a maximum cross-sectional dimension and a length-to-maximum-cross-sectional-dimension aspect ratio of 1:1 or greater. Each of the one or more shafts includes either: (A) one or more axial cross profiles including: a first bar having the maximum cross-sectional dimension; and a second bar having a cross-sectional dimension less than the maximum cross-section dimension, wherein the second bar is parallel to the injection-molding parting line; or (B) one or more axial elliptical profiles including: a major axis having the maximum cross-sectional dimension; and a minor axis having a cross-sectional dimension less than the maximum cross-section dimension, wherein the minor axis is parallel to the injection-molding parting line.
