Freud 34-120 1/4 Inch Radius Rounding Over Edge Router Bit

The Freud 34-120 is a 1-1/4-inch overall diameter rounding-over router bit engineered to shape smooth 1/4-inch radiused edges on furniture components, cabinet frames, and architectural moldings. Built with a heavy-duty 1/2-inch shank and Freud’s patented Quadra-Cut™ 4-cutter geometry, this tool employs two up-shearing and two down-shearing carbide blades to eliminate cross-grain tearout and surface fuzzing. Tipped with TiCo™ Hi-Density Micrograin Carbide and protected by a heat-resistant Perma-SHIELD® non-stick coating, it operates safely at speeds up to 18,000 RPM across solid hardwoods, softwoods, plywood, and composites in CNC machines, router tables, or handheld routers.

Best Used For:

  • Furniture & Tabletop Edge Profiling: Shaping smooth 1/4-inch radiused outer borders on solid wood table tops, desk edges, shelves, and chair rails.
  • Cabinet Door & Frame Edge Softening: Milling tearout-free rounded edge profiles on interior cabinet doors, drawer fronts, and frame moldings.
  • Cross-Grain Architectural Molding: Cutting smooth decorative border profiles across abrasive end-grain stock and composite sheets without post-routing sanding.

Key Performance & Safety Features

  • Quadra-Cut™ 4-Cutter Technology: Employs 2 up-shear and 2 down-shear carbide cutters to shear wood fibers simultaneously from top and bottom for a splinter-free finish.
  • TiCo™ Hi-Density Micrograin Carbide: Custom titanium-cobalt carbide formulation extends cutting life and maintains high edge sharpness under heavy production loads.
  • Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against heat buildup, pitch accumulation, and thermal corrosion.
  • Dual-Profile Convertible Versatility: Converts from a rounding-over profile to a decorative beading bit by swapping to a 3/8-inch outer diameter pilot bearing.
  • Precision Pilot Ball Bearing: Includes a 1/2-inch outer diameter steel guide bearing for consistent, uniform tracking along straight or curved edges.
  • Computer-Balanced Anti-Vibration Body: Precision body balancing eliminates chatter and ensures smooth rotational tracking at speeds up to 18,000 RPM.

What's Included

  • (1) Freud 34-120 1/4" Radius Rounding Over Router Bit with 1/2" Shank
