Freud 38-612 1-1/8 Inch Classical Cove and Round Router Bit

The Freud 38-612 is a 1-1/8-inch overall diameter classical cove and round router bit engineered to shape compound architectural profiles on cabinet doors, furniture edges, and custom millwork. Built with a heavy-duty 1/2-inch shank and Freud’s patented Quadra-Cut™ 4-cutter design, this tool uses two main cutters alongside two up-shearing secondary cutters 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 handheld routers or router tables.

Best Used For:

  • Architectural Millwork & Trim Profiling: Shaping compound classical cove and round profiles on solid hardwood casings, baseboards, and decorative trim.
  • Cabinet Door & Drawer Edge Detailing: Milling precise decorative border edges onto solid wood cabinet panels, drawer fronts, and face frames.
  • Furniture & Plaque Edge Softening: Cutting smooth decorative classical borders along solid wood tabletop perimeters, desk edges, and display plaques.

Key Performance & Safety Features

  • Quadra-Cut™ 4-Cutter Technology: Employs 2 primary cutters and 2 up-shearing secondary cutters to shear wood fibers cleanly for a splinter-free surface.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt carbide tips deliver high wear resistance and maintain edge sharpness under production heat.
  • Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against heat collection, pitch accumulation, and thermal corrosion.
  • Precision Steel Pilot Bearing: Features a 1/2-inch outer diameter pilot guide bearing for accurate, fence-free template tracking along curved or straight edges.
  • 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 eliminates chatter and ensures smooth rotational tracking at operating speeds up to 18,000 RPM.

What's Included

  • (1) Freud 38-612 1-1/8" Classical Cove & Round Router Bit with 1/2" Shank

Pro-Tip: Take initial light passes when routing deep classical profiles in dense hardwoods like oak or maple; incremental cuts allow the Quadra-Cut secondary cutters to polish the profile smoothly without burning.
