My bathtub's shower diverter spout leaks when it's in shower mode, so I'd like to replace it. It's the screw-on type. Trouble is, it's stuck tight. I've applied a lot of torque (counter-clockwise) with a pair of channel-locks and it simply won't budge. I'm worried about snapping the copper pipe if I go any harder. The actual joint is deep inside the spout so there's no access to spray penetrating oil or something in there. Am I gonna have to grind it off with an angle grinder or something to access the threads?

Quite possibly. I have cranked on spouts like that and had them release, and had them fold up and crumble, since it was old pot metal. A grinder would be a good way to go about it. The connection, if it is as you say, will be in about 3" in. The rough in for a connection like that is usually 4" to 4 1/8" to the end of the male adapter, so a cut about 3" should get you to the adapter.
