Surgical drill bits designed to be held and revolved by a rotary device to mill out the surface of bones usually along a template, permitting the surgeon to achieve accurate and reproducible results. These drill bits typically consist of a cylindrical shank of steel or other hard metal alloy with a uniform cross-section and cutting edges that may be tapered at the working end. They come in a variety of different shapes according to the orthopedic procedure and have a notched or short proximal end to fit into the rotary device (e.g., a hand drill, bone router). Routing bone drills are mainly intended for reshaping bones during orthopedic procedures, including minimally invasive surgical procedures of the articulations (e.g., knee). They are usually intended for reuse after sterilization, but can be disposable (single-use).
