- Carbide quality: Better carbide usually means cleaner cuts and longer life.
- Coating: Anti-stick coatings help when routing resinous woods.
- Compatibility: Make sure the bit set matches your board thickness and router collet.
- Project type: Cabinet doors, flooring, and paneling may each benefit from different sizing.
