I'm rebuilding my grates out of fire brick. Any idea how easy/hard it is to drill fire brick. I've cut fire brick pretty easily over the years to brick a few different arches, but have never drilled the stuff.
I'm looking to drill 3/4" or 1" inch holes with a mason bit to allow some of the ash to fall through, and more importantly, to allow some forced air to come up through.
Any of you guys that have done this, were you able to find pre driiled brick, or did you have to drill it yourself?
