Drill with a 1" drill, then come back with a 1" 2-flute endmill that has had one flute ground back, making it into a 1" single-flute end mill.
Essentially boring the hole flat and true. You can leave the outside edge flute but take the corner and the end-cutting edge off of one side, the non-center-cutting side.
I`m not questioning your knowledge, I`m a complete newb but I`d like to ask your reasoning behind using the method you suggested. Since the hole depth is only 1/4" why not just use a 1" centering end mill. The point on a 1" drill is almost 1/4". Would`t it be tough to guess the proper depth to stop with the drill ? and why ground off one side of a 2 flute EM ? I think I know the answer you`ll give but I want to make sure I`m close..LOL
