What specs actually matter when buying a router bit set?
| Spec | Why it matters | What to look for |
|---|---|---|
| Shank diameter | Fits your router collet | 1/4 in (6.35 mm) or 1/2 in (12.7 mm), stated exactly |
| Carbide grade | Edge life in hardwood and MDF | Micro-grain carbide, not "tungsten steel" marketing language |
| Bearing | Template and flush work accuracy | Sealed bearing, replaceable; a loose bearing ruins edges silently |
| Distinct profiles | Real utility | 12 different shapes beats 24 with repeats |
The mistake people make: buying on "HRC" numbers alone. HRC is a hardness scale for the steel substrate, not for the cutting edge; it tells you little about edge life in wood.
How to check before buying: ask for the shank diameter in mm and inches, the carbide type, and whether bearings are replaceable. A seller who cannot answer all three is reselling.
