Hi all. I am not a machinist by any means, but i have a (maybe) dumb question.
I have some 3/8" thick 6061 AL plate that i want to drill a 22mm hole through. Also, on the same center I'd like a 28mm hole halfway through, as the picture shows:
However, I only have limited tools - a handdrill, a drill press, etc...
Question: is it possible to do this with the tools i have, assuming i am will to spend a few bucks on bits or whatever? Would a combination of spade buits work? Also, it is not necessary to have it super accurate.
Thanks,
Byron
