Straight and Spiral Router Bits for Plastic
The smooth flutes and sharp cutting edges on these router bits cleanly cut square slots, pockets, and edges in most plastics, including polyethylene, polycarbonate, and vinyl. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.
Use carbide bits for longer tool life and faster cutting speeds than high-speed steel.
Bits with spiral flutes leave a smoother finish than straight-flute bits. 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.
Bits with a plunge cut type let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work such as trimming, contouring, and finishing.
Choose a bit with one flute for a faster cut; bits with more flutes produce a smoother finish.

Drill/Rout Router Bits
Drill, rout, and trim with the same bit. The unique shape on these bits was originally used for aircraft panels. They have a pointed end and spiral flutes, like a drill bit, making downward plunge cuts easier than with square-cut and straight-flute bits. The spiral flutes also leave a smoother finish. The flutes lift chips up from the workpiece for applications that require a clean finish on the bottom edge of the cut. Securely clamp your material before routing to prevent lifting.
These bits are made of high-speed steel for general purpose use. They can be used with hand tools, router tables, and CNC machines. These bits do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

Router Bits for Composites
The sharp cutting edges and flute shapes of these tools are specifically designed to cut through tough composite materials, such as carbon fiber and fiberglass, with minimal resistance. This means less strain on your router and more control when cutting, leading to smooth cuts. They're made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.
Diamond-Pattern Flutes—Small, staggered teeth aggressively cut, yet leave a smooth finish.
Use bits with a square cut style to cut slots, pockets, and edges. Bits with a drill/mill cut style have a pointed end for easier plunge cuts than bits with a square cut style.
Plunge-cutting bits let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work, such as trimming, contouring, and finishing.
