Hello to all:
You can try masonry bits till you are blue in the face,
they will not work. They are for drilling masonry not glaze (a glass like
substance). The only thing that will work are diamond bits... Whether it is a
diamond dremel bit, or a diamond impregnated drill bit, diamond bits are the
only thing that will drill glaze period... And you must drill slowly or you
will just burn the diamond coating up. If you use a dremel again go slow. You
can usually find diamond bits at any home depot or any of the better hardware
stores. Good Luck.

No matter what kind of drill bit you use, it helps to make a putty ring on the
surface and put a bit of light (like 3 in 1 ) machine oil in it to keep the bit
cool and keep it from splintering the glass. My dad used to do that to drill
holes in gallon bottles of Scotch or Magnums of champagne and make them into
lamps. this was back in the 40's and 50's when our part of NC was bone dry.
So when people went "Up Nawth" where you could get licker in glass bottles,
they would get these and when they were finished, bring them over and my dad
would drill the bottle out. its funny but now they do that to the old hand
thrown gallon jugs.

If you ask for a bit that will drill through ceramic, and there is someone
there who knows about bits, they will give you a diamond drill bit. I've
used it successfully in my dremel and in my variable speed drill. Home
Depot sometimes has people working for them that know about hardware, but
not always... I usually go to a hardware store that is a little more
expensive, but with a staff that knows how things work.

don't recall saying masonry bit
try tile/glass drills - come in all sizes from about 1/8" to at least 5/8".
needs low speed, may help to lubricate. solid tungsten carbide spade bit in
steel shaft. doesn't need a Dremel, or the speeds that a diamond bit needs.
could use in a hand drill with care starting off the hole.
diamond would work fine, if you have the gear - if not, these bits are cheap
and they do work. if you want to drill hundreds of holes, make the holes
and don't glaze them. if you want to try a cheap drill that will work on
glass and glaze tiles (OK - probably soft glazes on these, but it will work
on others) to just clean out a hole, and you don't have a diamond
drill/Dremel, try 'em.
I do use diamond drills for other things, by the way...

Get the tungsten carbide spade bit set for glass and tile from Harbor
Freight for about $7.00. We occasionally need to drill out holes that have
filled with cone 10 glazes in salt and pepper shakers as well as enlarging
the holes in lamp bases and other things. The "secret" is water. The bits
bite and chew through glaze easily when kept wet, but dull and burn up
quickly when dry. We use slow speeds to do this and it works fine.
