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.

60° Compression Spiral Flutes—The unique cutting angle and sharp edges slice through difficult material such as aramid. Often used in the aerospace industry to cut wings, rudders, and other structural components. They have upward and downward chip removal—acting similar to scissors, they move chips away from the top and bottom edges of the cut for a smooth finish on both.

Use bits with a square cut style to cut slots, pockets, and edges.

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.
