I bought a #55400 tongue and groove cutter. I don't know how to remove the nut on the end of the router bit to change the configuration from the tongue to the groove. How do I hold it without damaging its surface? Thank you.

Many of today's router bits, such as the tongue & groove router bits and reversible stile & rail router bits, use a hex nut to hold cutters on the shank.
By removing the hex nut you can rearrange the cutters in various ways. To avoid damaging the shank first secure the bit in a router. The router collet will grip the shank without damaging it.
When rearranging the cutters it's important that they face toward the direction of rotation (counter clockwise) as you view the router bit from the end with the nut.
