I've got a 2006 model 18.5" Weber kettle and I've recently become interested in BBQ. I'd like to 'notch' my Kettle so that I can run the Maverick probe leads without them getting crimped. I don't have an angle grinder but I do have a Dremel with cutoff wheels that are supposedly for cutting metal. Specifically these are the 1.5" EZ-Lock style metal cutoff wheels. Any advice before I cut away?
