You can get hardened drill bushings from most machine tool suppliers, 
although you could easily build one yourself if you have a drill press and 
a set of numbered drills.  I made quite a few along the way for my project 
using chunks of maple, and have a couple from aluminum and steel as 
well.  Cut the blocks to whatever size is convenient for the place you need 
to drill and drill them out with a numbered or lettered drill the next size 
up from the drill size you intend to use.  If you have the room you can 
clamp them to the workpiece, if not, holding them tight against the part 
works just fine, maybe even better.  When you hold them manually you can 
really feel when the hand drill is starting to misalign.  As long as the 
table to your drill press is perpendicular to the quill these hand made 
jobs work just great.  FWIW.
