I bought a used workbench yesterday. Its a small size (52" x 22") but its
heavy as heck - made out of hard maple with a 2 1/4" top. It has dog holes
running from front to back to complement the front vise. I want to add an
end vise and drill some dog holes to work with it. I'd like to drill the
holes as close to the front of the bench as I can.

What's the minimum distance from edge of the bench for dog holes? Remember
its 2 1/4" hard maple.

A good rule of thumb when drilling holes in most materials is never let the
edge of a hole be closer to an edge than the diameter of the hole.
