The Yonico 14983 Top and Bottom Bearing Router Bit is great for all your trim applications. This bit can be used with either a top or bottom template. Especially useful for template work when routing rounded or curvy wood with sensitive end-grains. Top and bottom bearing flush trim 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.
