14 Fuss-free router-bit setup
Add a temporary depth stop
If a router bit hits the bottom of the collet, you can't tighten it fully, creating the potential for the bit to work loose in use. And with some routers it's difficult to hold the bit at the correct depth while simultaneously tightening the collet nut. To prevent this, slip a snug-fitting O-ring onto the bit shank to hold it in place while you tighten the nut. You could also drop a small rubber grommet into the spindle to prevent bits from bottoming out. When you tighten the nut the rubber will flex as the bit shank draws against it. (You'll find O-rings and grommets at most hardware stores.)
