Surgical drill bits designed to be held and revolved by a rotary device for percutaneous perforation of bones or fragments of bone. These devices drive wires (known as Kirschner or K-wires) into the bone through the skin. These drill bits typically consist of a cylindrical hollow shank of stainless steel or other hard metal alloy with a uniform cross-section. They include a cutting edge (e.g., twisted, helicoidally) and a small hole at the working end and a notched or elongated proximal end to fit into the rotary device (e.g., a hand drill, handpiece). Wire-pass bone surgical drills are available for a variety of procedures such as holding bone fragments together (pin fixation) or to provide an anchor for skeletal fixation.
