neilestrick Posted August 28, 2012 Report Share Posted August 28, 2012 Diamond bits are good. You may be able to get through with a masonry bit, too. Super easy to drill low fire pots, really hard with high fire. But keep some water on it to keep it cool. If it gets too hot the pot will crack.

I fired at 06....what do you think? Thanks for the speedy reply Getting ready to go buy a bit! ;-D Link to comment Share on other sites More sharing options...
neilestrick Posted August 28, 2012 Report Share Posted August 28, 2012 A masonry bit can get through cone 06 pots fine. Link to comment Share on other sites More sharing options...
scoobydoozie Posted August 30, 2012 Report Share Posted August 30, 2012 I've used Truebite carbide cutting bits since the late 1980's and they are the best! They cut thru ceramic, glazed or unglazed. Be careful about side wobble and go slowly with light pressure as these puppies cut fantastic! I've used them to drill out salt and pepper shaker holes and christmas tree light holes that have been accidentally glazed over. That tips are not flat, but "spiked" which gives them extra umph. When using the smallest sizes, a little water to keep the tip cool is recommended. Just drill a bit, and then stop and dip in a cup of clean water to cool every so often. Helps keep you from breaking off the tip when drilling tiny holes like salt and pepper shakers. Can't recommend highly enough. http://www.truebite.com/drill_degrout/ Link to comment Share on other sites More sharing options...

christerrell Posted September 23, 2012 Report Share Posted September 23, 2012 Thanks for the tips, I was about to start a topic on this as I've had this happen on a porcelain teapot. I'm going to try a Dremel with a glass cutting bit. The pot's nice but until I get those holes clear, it won't pour! Link to comment Share on other sites More sharing options...
