A drill bit integrated with a retractable deburring cutter can be used for drilling and deburring exit burrs in a single process. In preliminary works, the authors learned that the retractable cutter may cause hole widening during its passage through the holes. A new design for the deburring cutter is proposed to avoid hole widening. With the new design, mild exit burrs (types I and II) are successfully removed. For large exit burrs (type III), however, the deburring is likely to be incomplete.
