Small Pilot Roundover Bits
If you need to get into a tighter radius area, you can use the Small Pilot Roundover router bit which features a narrow diameter brass bushing in place of a bearing. Keep in mind that the bushing spins when contacting wood, so lighter passes are needed to avoid burning your wood.
