Abstract
A drill guide with integral drill bit is provided for drilling a hole into bone. The drill guide may have a housing for engaging a screw hole of a bone plate to fix the trajectory of the drill guide and drill with respect to the bone plate. An adjustable stop assembly is also provided and is axially slidable along the drill bit. The adjustable stop has a drill bit engaging mechanism to selectively lock the adjustable stop to the drill bit at a desired location to limit the depth that the drill may penetrate into the bone.
