The saws in these kits have carbide-grit-coated teeth that cut ceramic tile, fiberglass, masonry, plastic, and composites. Attach hole saws to a drill or drill press with the included arbors.

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.

Trapezoid-Pattern Flutes—Like diamond-pattern flutes, but with overlapping cutting edges for an even smoother cut.

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.
