Masonry bits will work too. Go slow and keep it wet with water for lubrication. A drill press is ideal.
Read the full replyI just purchased a large ceramic pot which has a 1/4 inch hole at the bottom.
I need to fit the pot over a 1 & 3/4 inch pipe to use in an outdoor fountain.
is there a tool that I can use to enlarge the existing hole to 1 1/4 inches? I have a 3/4 inch battery driven drill. can also use a direct power drill. I don't know whether I should use something like a bit that saws, a bit that files, a bit that drills, etc.
all replies, opinions, suggestions, etc. welcomed! Aaron in N. Hollywood
Large bullet grinding stone in a drill press. If it isn't big enough move the pot around the stone until you are done. A hand drill can work...but....
Having a partner spraying the stone/pot with water with a spray bottle will help keep down the dust and keep things running cooler...
You should also be able to get a large enough hole saw for ceramics (RemGrit is a brand, I think) which could be used with a drill press, or even a hand drill if you can find one with a 1/4" pilot bit.

You can make a bullet stone out of a 1 1/2 round stone in a pinch. It's cheap!
Reduce the pipe feed?
Rattail file.

Use a masonry bit and drill extra holes.
VERY dangerous. Some ceramics completely shatter. Especially Italian stuff.
A diamond burr in a Dremel can work well.
I used a Dremel tool to drill a hole in the bottom of a teacup so I could use it for a small plant. Worked fine. Grinder-type bit with rounded tip. Check the user manual. Just took it slow and easy, not a valuable item.
To 1/4" OD ??
I have a hole-saw kit that would work. It comes with different sizes up to 2 1/2 in.
PROBLEM SOLVED. We used a large masonry bit which was not as large as the 1 and 3/4 in. size we desired and simply slowly went up & down the sides of the existing hole which enlarged the hole to the desired size. The entire process was well under 5 minutes.
We do appreciate the informative replies we received on the original post and thank all for them. Best, Aaron
