Shop CNC Router Bits By Material
Pick the material you're cutting — geometry and chipload matter far more than brand. Every bit lists its own manufacturer feeds and speeds on its product page.
Hardwood & Softwood2,013 bitsSolid wood. Chipload runs high — Onsrud specifies 0.014–0.016″ per flute at 1/4″ in hardwood.
Plywood & MDF2,011 bitsCompression spirals protect both face veneers. Top-face fuzz means upcut; bottom blowout means downcut.
Melamine & Particleboard259 bitsBrittle surface over a soft core. Compression geometry, a sharp edge, and don't under-feed.
Aluminum & Non-Ferrous190 bitsSingle or two flute, polished flutes, and lubrication — aluminum welds to the tool if chips can't clear.
Acrylic & Plastics155 bitsSingle-flute O-flute. Melting is almost always chipload too low, not feed too fast.
Fiberglass & Composites84 bitsAbrasive. Diamond-pattern and chipbreaker geometry to survive glass and carbon fibre.
Solid Surface21 bitsCorian and similar. Clean shear and heat control keep seams invisible.
Cutting badly right now?
If the material is melting, chipping or tearing out, the fix is usually parameters rather than a different bit:
