Abstract
A self-centering bone drill comprises a drill bit having a proximal end and a distal end, a cutting surface at the distal end, and a first radially extending flange. A tubular housing coaxially receives the drill bit and a spring is coaxially received within the housing, and coaxially receives the drill bit. The spring is compressed between the first radially extending flange and an interior abutment surface on the housing distal of the first radially extending flange to urge the housing distally along the drill bit. A chamfered surface on a distal end of the housing engages a chamfered surface on a work piece to center the drill bit.
