Abstract

An annular cutting tool and related methods are provided for herein that exhibit improved durability, cutting performance, and/or reduced heat generation for bone graft resections. The annular cutting tool can include an annular body having cutting teeth with a flat, flared distal tip for greater durability. An extended gullet can be disposed between groups of adjacent cutting teeth to improve removal of bone debris away from the cutting teeth more and thus prevent binding during use. The annular cutting body can have a recessed surface portion to reduce the area of direct contact to bone and thus reduce heat generated. The recessed surface portion can also provide an area in which bone debris can accumulate away from the cutting teeth to prevent or reduce binding of the tool during use. The annular cutting body can also include a drill bit for drilling a hole in a resected bone graft.
