Warning: Make sure the router bit is properly fastened and tightened in the router’s collet and the bit can rotate freely without any obstructions.
Instructions: Slowly dial up the RPMs on your router to the recommended maximum. Then, dial back if needed to find the “sweet spot”. The sweet spot is the speed at which the least resonant vibration is present. If the sweet spot cannot be achieved within 5,000 RPMs of the max, check the collet for residue or other debris and start over.

Top and bottom bearing flush trim router bits are used to trim the edges of wood stock that have sections of tricky end grain which are subject to tear out. The direction of cut will significantly effect the results. Having the option to use either the top or bottom bearing as a trim guide will give you the option to flip the workpiece and either ramp or climb the woodgrain. As with all trim bits, choosing the largest diameter that will accommodate your workpiece will yield the smoothest finish.
