Freud/Diablo 30-111 is a carbide-tipped 5/16" radius Cove Bit designed to deliver clean, consistent edge profiles on a wide range of woodworking projects. This core box bit creates the classic concave edge that’s a staple in decorative and functional edging, making it a go-to choice for furniture, cabinetry, and trim work.

What makes this bit stand out:

• 5/16" radius cove profile produces a subtle, rounded edge perfect for cabinet doors, table edges, picture frames, stair rails, and decorative trims.
• Carbide-tipped construction offers long tool life and excellent wear resistance, staying sharp through hard and soft woods, plywood, and composite materials.
• Shear-angle geometry slices like a hand plane, dramatically reducing tear-out on figured or irregular grain and delivering smoother finishes in challenging wood.
• Versatility in your shop compatible with both hand-held and table-mounted routers, enabling freehand edging or precise, guided edge treatments along longer workpieces.
• Consistent, high-quality results from Freud’s precision engineering, helping you achieve uniform profiles and cleaner edges with fewer passes.

Practical use and application ideas:

• Create graceful edge details on cabinet doors, drawer fronts, and top rails for a timeless, professional look.
• Profile decorative edges on signs, frames, and hobby projects where a soft, curved edge enhances the design.
• Edge softening on tabletops or shelving where a subtle radius adds comfort and visual appeal while maintaining overall dimensions.
• Work with both softwoods and hardwoods; when routing figured grain, use light passes and let the shear-cut power do the work to minimize tear-out.
