Composite Plastic

Fiberglass-reinforced plastic (FRP), carbon fiber composites, and G10/FR4 laminate are abrasive enough to wear a standard bit fast — the glass or carbon fiber itself acts almost like sandpaper against the cutting edge, which is...

Fiberglass-reinforced plastic (FRP), carbon fiber composites, and G10/FR4 laminate are abrasive enough to wear a standard bit fast — the glass or carbon fiber itself acts almost like sandpaper against the cutting edge, which is the main reason these materials need dedicated tooling rather than a general-purpose plastic bit.

Solid carbide construction holds up to that abrasion better than coated alternatives, with geometry aimed at clean cuts without delamination — composite panels separate into layers under the wrong cutting approach, which a standard wood or plastic bit doesn't account for.

Common in aerospace, marine, and industrial fabrication where composite panels are structural, not just decorative.
