Straight and Spiral Router Bits for Plastic

Square Cut Style

Straight Flute

Spiral Flute

Cut square slots, pockets, and edges in plastic.

Bits with straight flutes are for general purpose use.

Bits with spiral flutes make plunge cuts more easily than straight-flute bits and leave a smoother finish. Spiral-flute bits with upward chip removal lift chips up for applications that require a smooth finish on the bottom edge of the cut. Securely clamp the workpiece before routing to prevent lifting. Spiral-flute bits with downward chip removal push chips down for applications that require a smooth finish on the cut's top edge.

High-speed steel bits can be used with hand tools, router tables, and CNC machines. They do not have a pilot, so guide your router along a straight edge when hand routing to ensure accurate cuts.

Carbide bits provide a longer tool life and faster cutting speeds than high-speed steel bits. Their extreme hardness means they are brittle, so they’re not recommended for use with hand tools. A highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking.

Bits for hard and soft plastic are for use on most plastic, including polyethylene, polycarbonate, and vinyl. Choose a bit with one flute for a faster cut; bits with two flutes produce a smoother finish.

Bits for hard plastic and composites have two shallow flutes for durability when making cuts on hard material.

Flush-Trimming Router Bits

Flush-Trimming Cut Style (Bottom Pilot)

Carbide (Spiral Flutes)

Cut layers of material flush to one another or make cuts along a template. All bits have a pilot to guide cuts.

Pilot location describes the position of the pilot when the bit is used for hand routing. The pilot location is reversed when using the bit with a router table.

Bottom-pilot bits trim material from an upper layer of the workpiece so that it is flush with the layer below. In addition to flush trimming, they can be used to cut along a template placed below the workpiece. Micrograin carbide and diamond-tipped carbide bits are for use on aluminum.

Corner-Rounding Router Bits

Rounded Corner Style (Carbide)

Choose from bits that cut rounded, cove, wavy, or Roman ogee corners along the edges of your workpiece.

Use solid carbide bits to round off sharp edges on plastic sheets. Their extreme hardness makes them brittle, so they're not recommended for use with hand tools. A highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking.

Ball-End Router Bits

Ball Cut Style

For smooth contour carving in wood, plastic, and aluminum, these bits have a ball-nose design. All are made of solid carbide for a long tool life and fast cutting speeds. The extreme hardness of carbide bits means they are brittle, so they're not recommended for use with hand tools. A highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking. The spiral flutes pull chips up from the workpiece while making cuts; securely clamp your material before routing to prevent lifting.
