I also do/teach stained glass. The bits are in the $25 dollar range with
something close to .25" hole. Not always, no standard. The bit makers
also make the grinders. No reason for compatibility. Plan on making an
arbor.
If you do a lot of glass, a glass grinder can be had for under a hundred
bucks.
Keep it clean and don't abuse it, will last long time. Be careful grinding
mirror,
find a fine bit. Will chip the plating off the back. If you go the drill
press route,
ALWAYS have a water drip on the bit.
