Straight profile router bits can create straight grooves, dados, and slots in a surface. They are used to hollow out areas in a workpiece. These router bits have an open-flute design that provides efficient chip clearance in applications with high feed rates.

Roundover profile router bits cut a rounded quarter-circle edge on a workpiece. They are used to round the edges of tables, chairs, cabinets, and other furniture or home fixtures.

Chamfer profile router bits create a 45° angled edge on a workpiece. They are also known as bevel-tip profile router bits.

Panel-pilot profile router bits are used to make openings in paneling, siding, drywall, windows, doors, and similar surfaces. They are also used to trim mica, veneer, and other laminates.

Hinge-mortise profile router bits cut a mortise (or recess) into a workpiece. They can also create dados or rabbets. These bits are used to inset hinge leaves and stair treads and to carve large, shallow recesses into a workpiece.

Rabbet profile router bits make a rabbet (a recessed 90° shoulder) in a workpiece. They are used in cabinetry and woodworking to create secure joints between two workpieces.

Tongue-and-groove profile router bits create tongues and grooves on the edges of wood paneling, flooring, parquet, and similar materials so the materials can be securely joined together.

Round-groove profile router bits make round-bottomed grooves in a workpiece. Also called core box profile router bits, they are used to flute moldings, columns, millwork, and signs.

V-groove profile router bits create V-shaped grooves in a workpiece. They can also be used for chamfering edges, miter work, or for sign and letter work.

Roman ogee profile router bits create an S-shaped edge on a workpiece. They are used to shape molding and tabletop edges.

Beading profile router bits create a quarter-round edge with fillets on the top and bottom. They leave a square shoulder at the top of the cut.

Drawer-lock profile router bits cut narrow, wedge-shaped tenons and mortises for joining two perpendicular workpieces without using nails or screws. Sometimes called drawer-and-lock router bits, they are used to join the front and sides of drawers.

Cove profile router bits leave a concave rounded edge on a workpiece. They are used to shape trim that will be used to bridge a gap between a wall and a floor.

Dovetail profile router bits create tapered, fan-shaped tenons and mortises on the edges of two parts so that the parts can be joined together without nails or screws.

Half-round profile router bits create a rounded half-circle edge on a workpiece. They are used to shape the edges on furniture and molding and to make a rounded edge on dimensional lumber.

Door knob profile router bits are used to create different sizes of door knobs. These bits are used in drill presses and boring and milling machines.
