Cove bits: These bits are used for creating concave profiles in wood.
Chamfer bits: These bits are used for beveling the edges of wood.
Flush trim bits: These bits are used for trimming the edge of one piece of wood to match the contour of another piece.
Dovetail bits: These bits are used for creating dovetail joints, which are commonly used in cabinet and furniture making.
Rabbeting bits: These bits are used for cutting rabbets or recesses in wood.
Beading bits: These bits are used for creating decorative edges on wood.
