I'm no expert but although it's at the low end I think it will do

I seem to recall speeds upwards of 100,000RPM in volume production using multiple drill presses but this is for efficiency no doubt. There are many small, specialised PCB drilling machines using 10,000 - 30,0000RPM but I'm sure 8,000RPM or so is fine.

My understanding is that the high speed provides a much cleaner hole through the different layers, especially the copper. And it's fast, like a hot knife through butter!
