Are diamond-coated router bits worth it?
| Material | Diamond coating | Better choice |
|---|---|---|
| Carbon fiber | Yes, big life gain | Also: compression geometry for fraying |
| Fiberglass | Yes | Diamond or solid carbide, dust extraction is mandatory |
| MDF and particleboard | Some gain | Standard carbide is enough |
| Hardwood | No benefit | Standard carbide |
| Aluminium | No | Single-flute carbide, wax |
The catch: a diamond film is microns thick, so sharpening removes it. You are buying a disposable edge with a long life, not a repairable one.
Safety note on composites: the dust is the real hazard. Cut wet or with extraction at the cutter, and wear a respirator rated for fine particulate.
