RE: [CAD_CAM_EDM_DRO] drilling techniques for plastic to get specific sized hole?

I actually was experimenting on the plastic... and found that if I
flipped it over, and chased it down with the same bit and some water...
it would slip on nicely.

The water helped out a lot I think, but chasing it down again flipped
over, seems to work too.

What I was doing wrong before was incremental bits, and no lube... (heh,
I'm new to this stuff)

Thanks everyone, for their advice...
