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.
