Small Grooving Bits such as the Plunge Ogee are commonly used for decorative designs in cabinet doors or for detail veining in furniture. Round Nose Bits and V-Groove Bits are often used in the same manner. The larger Grooving Bits are great for a raised panel effect in doors and for adding a bold accent to furniture or large work pieces. These bits also make nice edge profiles with the aid of a router table and fence.
