Precision Freud 1-3/8 Inch Quadra-Cut Roman Ogee Router Bit 38-172 with 1/2 Inch Shank

The Freud 38-172 1-3/8-Inch Diameter Quadra-Cut Roman Ogee Router Bit operates as a commercial-grade decorative profiling tool engineered to execute classic 5/32-inch radius Roman Ogee edges with an inset bead profile on solid hardwoods, softwoods, cabinet plywood, and wood composites. Manufactured with four micrograin TiCo High-Density Carbide cutters coated in friction-reducing Red Perma-SHIELD non-stick coating, this heavy-duty 1/2-inch shank bit features a 3/4-inch pilot ball bearing, a 1/2-inch carbide height, and a 16,000 RPM maximum speed rating. Compatible with handheld portable routers and router table setups, this patented four-cutter profile bit utilizes two up-shear wings to clear core material and two down-shear wings to slice top surface fibers, delivering a splinter-free, hand-planed surface finish across cabinet doors, drawer fronts, and architectural millwork.

Best Used For:

  • Architectural Cabinet Door Edging: Milling classic 5/32-inch radiused Roman Ogee decorative borders along solid wood cabinet door stiles, face frames, and drawer fronts.
  • Tabletop & Furniture Edge Profiling: Shaping clean Roman Ogee edge profiles with an inset bead on tabletop perimeters, display plaques, and furniture trim.
  • Guided Substrate Edge Duplication: Tracing straight or curved workpiece edges using the integrated 3/4-inch pilot ball bearing to produce uniform architectural moldings.

Key Performance & Safety Features

  • Patented Quadra-Cut 4-Cutter Technology: Combines two up-shear cutters and two down-shear cutters to eliminate top-surface cross-grain tearing and fuzzing.
  • TiCo High-Density Micrograin Carbide: Proprietary titanium-cobalt carbide formulation maintains razor-sharp edges up to four times longer than standard carbide.
  • Red Perma-SHIELD Thermal Barrier Coating: Non-stick red fluoropolymer coating insulates the bit body against heat buildup, pitch accumulation, and rust corrosion.
  • Heavy-Duty 1/2-Inch Steel Shank: Provides maximum anti-flex structural stability and vibration resistance during deep 1-3/8-inch diameter profile cuts.
  • Integrated 3/4-Inch Pilot Ball Bearing: Smooth-rolling guide bearing tracks substrate faces accurately to prevent workpiece scoring or friction burning.
  • Computer-Balanced Dynamically Balanced Body: Precision-balanced tool body eliminates vibration and chatter marks at regulated speeds up to 16,000 RPM.

Pro-Tip: When routing 1-3/8 inch wide Quadra-Cut Roman ogee profiles in dense hardwoods, adjust your router speed setting to a maximum of 16,000 RPM to prevent friction burning. Make two light passes rather than a single heavy pass, allowing the down-shear wings on the final pass to glide across the top shoulder for an ultra-clean finish that requires no hand sanding.
