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.
An open mind is a virtue...so long as all the common sense has not leaked out.
hmm..for some reason my search yielded no fruit - thanks a lot!
you could get forenster bit to do big hole, works pretty good on aluminum, just use some lubricant(wd 40 or similar).
Send it to me with return postage and a $5 bill. I'll CNC it dead on. I'm slow right now. Priority mail flat rate is $4.20.
davereagan, thanks for the offer, but i will be trying the Forstner bit this weekend i think - i need to finish up this project soon
