I start with a reinforced cutting wheel on my dremel to cut a rough hole in the cowel, then use a 1/4" drum sanding bit to smooth it out.

Carbide or Diamond cutting wheel for the dremel (cuts like BUTTER!)...then touch up with with a flapper sanding wheel on the dremel.

use a torch to heat an #11 Xacto blade and it'll cut it like butter and there won't be any dusty mess.

To make perfectly round holes, use a cone shaped grinding stone mounted on either a die grinder or drill motor

Hi guys, I used the gas stove to heat up the xacto blade and it cut it like cut FROZEN butter, have to heat up the blade over and over and over but it beat the dusty mess when used the diamond cut blade with the dremmel.
I used the dremmel with the grinding fine stone to clean up the openings. It turned out very nice
THANKS EVERYONE.

As for all that dust, I took a center island table I had in my shop, cut out the center, reinforced it, and mounted peg board to the surface. I then boxed in the underside of the top and sealed it. With a hole in the side of the table, I can connect my shop vacuum and with it on it draws a good bit of air down through the peg board and into the vacuum. If I'm remotely careful about the direction the cutting tool throws the dust, the table/vacuum collects it all.
