Corob Molding Knife: #16 3/16″ Bead & Cove
This knife is best for small-scale bead and cove profiles. It mirrors the shape of the #15 option, offering a reliable 3/16″ bead and cove cut. The set includes three knives for quick profile changes, making it ideal for cabinetry detail work or hobbyist textures. Best for precise, consistent bead work in narrow trim
Who it’s for: hobbyists and small shop users who need a repeatable bead profile without changing knives frequently.

Who it’s for: professional woodworkers and cabinet shops needing a robust, long-lasting cutter for repeated use on complex moldings.
Caution: Ensure the bore sizes align with your spindle; data indicates multiple bore configurations, which may require adapters or exact matching equipment.
#25 Corob Curved Flute & Quarter Round Molding Knife
This knife excels for curved flute and quarter-round profiles. The three-knife set accommodates curved flute and quarter-round combinations and is designed for use with Corob Cutter Molding Knife head or Craftsman Molding Knife head.

Buying Guide: Key Purchase Considerations
- Profile type: Choose bead, bullnose, curved flute, or quarter-round profiles based on your molding needs. If you work with curved edges, favor curved flute or quarter-round knives.
- Material and durability: Carbide-tipped knives offer longer life on harder woods and plastics; high-strength carbide options are ideal for frequent, demanding use.
- Bore and spindle compatibility: Confirm bore sizes and compatibility with your router or shaper spindle. Some cutters require adapters for 1/2″ or 3/4″ spindles.
- Set availability: Some products come as a set of knives, which improves versatility and reduces downtime between changes.
- Application scale: For small projects, narrow beads (like 3/16″) are suitable; for furniture and cabinetry, larger radii and bullnose options improve efficiency.
- Maintenance: Look for mirror-finish edges and properly ground tips to reduce tear-out on delicate beading work.
