I have drilled many mouthpieces but none with a drill bit. Our on-campus repairman here at Ithaca College has a tool that looks like a mouthpiece truing tool. The only difference is...that it has blades on it. Place the conical tool down(gently) the throat and twist 1 turn. That 1 turn usually shaves off enough metal to comfortably enlarge the throat.
