Freud Router Bit 20-320 3/4 Inch 3/8 Inch Radius V Groove (1/4 Inch Shank TiCo Carbide Perma-SHIELD 24000 RPM CNC Sign Making Fluting Woodworking)

Freud 20-320 3/4 Inch Radius V-Groove Decorative Router Bit

The Freud 20-320 is a 3/4-inch overall diameter radius V-groove router bit engineered to rout smooth, rounded channels, fluted column details, and decorative rosette profiles in wood millwork. Built with a 1/4-inch shank and a 3/8-inch cutter radius, this 2-flute tool forms curved-bottom trough profiles without leaving sharp internal corners. Tipped with TiCo™ Hi-Density Micrograin Carbide and protected by a heat-resistant Perma-SHIELD® non-stick coating, it operates cleanly across solid hardwoods, softwoods, plywood, plastics, and composites in CNC machinery, router tables, or handheld routers.

Best Used For:

• Architectural Column Fluting: Milling smooth 3/8-inch radiused vertical fluting channels into solid wood pilasters, columns, and mantle casings.
• CNC Rosette & Sign Carving: Routing circular decorative rosettes, curved 3D background pockets, and soft-bottomed lettering on custom wooden signage.
• Decorative Cabinet Door Veining: Inscribing curved accent lines and radiused panel borders across solid wood cabinet faces and furniture panels.

Key Performance & Safety Features

• Precision 3/8-Inch Profile Radius: Ground profile cuts soft concave profiles to add depth and contouring to architectural millwork.
• TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt carbide tips maintain razor sharpness under continuous high-speed friction.
• Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against thermal heat collection, pitch accumulation, and rust corrosion.
• Deep 5/8-Inch Carbide Height: Extended cutter flutes allow deep single-pass fluting and decorative carving without body binding.
• Precision Dual-Flute Cutters: Two cutter flutes provide efficient chip removal and smooth surface finishes in plunge or lateral routing passes.
• Computer-Balanced Anti-Vibration Body: Precision body balancing eliminates chatter and ensures smooth rotational tracking during high-speed CNC routing.

Technical Specifications

Pro-Tip: When routing multiple parallel fluting grooves on column stock, use an edge guide or router table fence indexing pin to ensure precise, equal spacing between each radiused channel pass.
