Make quick work of changing router bits with the Bora Offset Wrench set.
If your router is mounted in a table, disconnect it from power, adjust the height of your router, and remove any support rings that might be in place at the opening of the router plate. Secure the wrenches around the collet nut at the 4 and 8 positions, as though on a clock face. Once in position, squeeze the handles together toward you. You will feel the collet nut release so you can remove it from the router spindle..
