After I posted my question I realized that I worded it very poorly, I apologize. First of all I use a router table with a fence, so the fence will control my cutter. Second it is not depth that I want to gain but the length of the reveal. The panel raising bit is 1 5/8 inches in diameter, the bearing is 1/2 inch so that the reveal is at most 9/16 wide. If I take the bearing off I can gain approximately 1/16 on the reveal (I didn't measure this, just eye-balled it). No, I don't want to buy a larger bit because I'm using my trusty old PC 690 in my table.
