Freud Router Bit 20-574 1-1/8 Inch 60 Degree Lettering Flat Bottom (1/2 Inch Shank TiCo Carbide Perma-SHIELD CNC Sign Making Relief Carving)

Freud 20-574 1-1/8 Inch 60-Degree Lettering Flat Bottom Router Bit

The Freud 20-574 is a 1-1/8-inch overall diameter 60-degree flat-bottom lettering router bit engineered to rout raised-letter sign backgrounds, flat-bottom relief carvings, and beveled profile details. Built with a 1/2-inch shank and a 3/4-inch carbide cutting height, this 2-cutter tool removes background stock while creating 60-degree beveled edges on raised letters in a single pass. 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, and composites in CNC machinery, router tables, or handheld routers.

Best Used For:

• CNC Raised Letter Signmaking: Milling flat background field pockets while cutting crisp 60-degree bevels around elevated lettering on wooden plaques.
• 3D Relief & Architectural Carving: Clearing flat interior recess pockets and shaping angled borders for custom architectural panels and wood carvings.
• Single-Pass Field Clearing: Routing wide flat-bottom grooves and background fields efficiently without requiring secondary straight bit tool changes.

Key Performance & Safety Features

• Flattened End Profile Geometry: Clears background material flat while simultaneously forming a 60-degree bevel around raised sign features.
• TiCo™ Hi-Density Micrograin Carbide: Custom titanium-cobalt carbide formulation maintains high edge retention under heavy production friction.
• Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against thermal friction, pitch accumulation, and rust corrosion.
• Extended 3/4-Inch Carbide Height: Provides deep cutter reach for tall raised letters and multi-layer relief carving passes.
• Rigid 1/2-Inch Steel Shank: Heavy-gauge shank diameter minimizes vibration, chatter, and cutter deflection under heavy rotational loads.
• Computer-Balanced Anti-Vibration Body: Precision body balancing ensures vibration-free operation during high-speed CNC routing passes.

Technical Specifications

Pro-Tip: Use raster toolpath strategies in your CNC software when clearing large background fields; step-over settings between 40% and 50% of the flat-bottom tip width produce smooth, ridge-free sign surfaces requiring minimal sanding.
