thinkandtink.com has bits, but be warned, they are kinda pricey at
almost $9.00 each.
they last longer if you can set the depth to just below the copper
and as the copper starts to burr (indicating a dull edge) you can set
the depth deeper and get a little more life from the tool.
My machine has 25,000 RPM as the top speed and uses that for all
drills up to 1/16th.
I don't have the pointed tool speed on this computer, but can let you
know that setting tomarrow.
