Reply to comment by Acrobatic_Wonder8996 in How does putting glass underwater, prevent it from breaking when drilling/cutting? by emelrad12

This is how I carve stone. I either submerge it in water or have a constant stream of water running over it to prevent the bit from getting hot.

Not just the bit: the material itself. Glass in particular has cracking issues when there is a high heat gradient on the material being drilled/cut
