Buying Guide: Crown Molding Router Bits
What should you consider when choosing a crown molding router bit set?
- Shank size and router compatibility: Most sets use 1/2-inch shanks, but some include smaller shanks. Confirm your machine accepts the shank and clearance for large crowns.
- Profile variety: Sets with multiple bits provide more crown shapes and profile combinations. Decide if you need side, cap, or beading profiles for your project.
- Material and blade quality: Carbide blades offer longer life and sharper edges. Look for sets with C3 or similar micro-grain carbide for longevity.
- Stock compatibility: Some bits are optimized for solid wood, others for MDF or plywood. Check your primary material to avoid tear-out.
- Use case: Table-mounted routers vs. CNC routers have different tolerances. Ensure the bits are designed for your main tool type.
- Maintenance and sharpening: Carbide bits can be re-sharpened in some cases. Consider the availability of local sharpening services if you plan heavy use.
