I'm in need of some guidance without breaking the bank...I'm trying to decide on how the most accurate way for me to cut a 3.25 dia. hole in apiece of 1/2" thick aluminum would be with a floor mounted drill press which has a MT2 spindle...The hole I'm shooting for needs to be clean without any ugly in the cut walls...accuracy doesn't have to be precise since the part that will go into the hole I can adjust for tight fit in my Lathe...I have several hole saws of various sizes but I fear that the quality of the hole would be sub standard as far as the wall finish...My chuck on the drill will only go to 1/2" I believe however it may stretch to 5/8" I just have not pushed this limit...
I have tossed around a carbide china hole saw set up specifically for the dia. hole but am concerned it may not be deep enough to cut thru the 1/2" plate aluminum
My hole saws are the older style where you have a arbor and attach the hole saw of desired size and lock down the locking nut...They spin and not very accurately at all...
Fly cutter???
Thoughts???
