Abstract
A stop is used for limiting the drill depth of an osteotomy drill bit within a bore in bone. This stop may have a generally tubular body for being releasably mounted on the drill bit and have a cam slot disposed at the body and used for defining a plurality of axial positions. The cam slot is configured for releasably securing a cam follower associated with a drill assembly that extends radially relative to a longitudinal axis of the drill bit assembly to axially secure the stop to the drill bit assembly. Additionally, the stop includes an apical end section that is configured to engage bone adjacent to the bore and limit the apical motion of the drill bit.
