Tip: If your setup allows you to plunge to cutting depth at the exit
point, doing so before making the cut that's producing tearout will
usually eliminate the tearout problem.

Corollary: If you have tearout at the beginning of a cut, try plunging
to your cutting depth with the center of the bit at the edge of the
stock.
