    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.

    Square Cut Style—Use bits with a square cut style to cut slots, pockets, and edges.
    Drill/Mill Cut Style—Bits with a drill/mill cut style have a pointed end for easier plunge cuts than bits with a square cut style.
    Plunge Cut—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.
    Diamond-Pattern Flutes—Diamond-pattern flutes' small, staggered teeth aggressively cut, yet leave a smooth finish.
    Trapezoid Pattern Flutes—Trapezoid-pattern flutes are like diamond-pattern flutes, but with overlapping cutting edges for an even smoother cut.

    Diamond-Coated Router Bits for Composites

    With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.

    Square Cut Style—Use bits with a square cut style to cut slots, pockets, and edges.
    Plunge Cut—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.
    Spiral Flute—Bits with spiral flutes leave a smoother finish than straight-flute bits and make plunge cuts more easily (for plunge-cutting bits).
    Roughed Spiral Flute—Nicks on the edges of the spirals reduce the amount of force required to cut through composites, giving you more control as you cut.
    Herringbone Compression Flute—Herringbone-compression flutes have both upward and downward spiral flutes in an alternating pattern. This quickly and effectively clears chips, which prevents overheating and produces clean cuts.
    Upward Chip Removal—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.
    Upward and Downward Chip Removal—Bits with upward and downward chip removal are also known as compression bits. Acting similar to scissors, they move chips away from the top and bottom edges of the cut for a smooth finish on both. Bits with higher compression angles cut more efficiently than bits with lower compression angles, reducing the amount of force required to cut through your material. They are also more resistant to wear.

    Image of Product. Front orientation. Router Bits. Trimming Router Bits , Uncoated Diamond-Tipped Carbide .
    Use carbide bits for longer tool life and faster cutting speeds than high-speed steel.
    Diamond-tipped carbide bits are for use on aluminum and composites.
    Bottom Pilot—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.
    Straight Flutes—Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.
    Ball Bearing—Ball-bearing pilots guide the bit for accurate cuts and produce less friction than solid pilots for smoother operation.
    Pilot Location—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.
