Abstract
A surgical cutting tool includes an elongated shaft and a cutting head. The shaft defines a coupling portion terminating at a proximal end of the shaft, a stem portion, and a distal portion. The stem portion defines a central axis. The coupling portion optionally defines a deflection surface positioned oblique with respect to the central axis and connected with a first driven surface and a second driven surface. Upon insertion into a drive chuck, the deflection surface promotes self-alignment of the cutting tool and the drive chuck.
