I have a customer wanting holes drilled thru the top wall of 1" square *aluminum* tubing, with 0.0625" wall thickness, for a 0.125" hole.
I have a PRS Standard machine, and I'm looking for any suggestions on the bit and speeds.
Also, if I need to run a lot of these, am I correct that a spindle would be much better than my current PC router?
thanks in advance,
John
