I have a bench-mounted router which is used for template routing. I use two router bits, one with the bearing above the cutter and the other with the bearing below the cutter. I start the cut with one bit doing half the cut and then stop and change the bit (at the same time turning over the workpiece to change the direction of the grain) before completing the cut. This stops the problem of tear out as the bit exits the cut when using template bits but it takes time to change the bits and to adjust the height.
The solution I have come up with is to remove the bearing and retainer from one bit and fit it to the base of the other. The bit featured below now has two bearings, one above the cutting edge and one below. I now start the cut with the bit going half way, stop, adjust the height and turn over the stock and complete the exercise. No more exit tear out and no need to change bits!
