    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.
    Drill/Mill Cut Style—Bits with a drill/mill cut style have a pointed end for easier plunge cuts than square-cut bits.
    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.
    Diamond-Pattern Flutes—Diamond-pattern flutes' small, staggered teeth aggressively cut, yet leave a smooth finish.
    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.
