Before putting the finished edge on sink cut outs, it is important to use these Overhang Trim bits to remove most of the material and leave only 1/8″ of top for your Round Over, Ogee, Bevel or Bull Nose bits to cut. This technique results in a much better finish and longer bit life. Specially formulated carbide is ideal for fabricating solid surface materials. Use these bits in your hand-held router.
