I've got a weber OTS franken-kettle mod in mind which would require some drilling, but I'm a bit fearful of cracking the ceramic.

Anyone care to share a successful approach to making clean drilled holes without cracking the ceramic, on both the kettle and lid, namely in the 1/4" and 3/4" sizes? Also appreciate any info on bit type and drill speed.

Thanks in advance,

I have drilled kettles without issues. Granted I have not done anything as large as 3/4".

Center or spot drill the hole first.

Use a smaller drill size first.

Drill to size.

Drill bits come in 2 different angles, 118 degree(included) angle is the most common, 135 degrees(included) angle, often called a split point drill is the other option. A 135 degree drill bit has much less tendency to "walk" or skitter across your work surfece, which is important when you are drilling something such as pipe or other rounded surfaces. I'd get a 135 degree drill bit for your 1/4" holes.

Both for cost and effeciency, I'd use a metal cutting hole saw for you 3/4" holes.

+1 on the metal cutting hole saw! You will get fantastic results with one.
