Precision Freud 1-1/8 Inch Quadra-Cut Beading Router Bit 36-122 with 1/2 Inch Shank

The Freud 36-122 1-1/8-Inch Diameter Quadra-Cut Beading Router Bit operates as an industrial-grade architectural edge-profiling tool engineered to execute a smooth 5/16-inch radius quarter-round edge with a distinct 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 finish, this heavy-duty 1/2-inch shank bit features a 3/8-inch ball bearing pilot, a 1/2-inch carbide cutting height, and an 18,000 RPM maximum speed rating. Compatible with handheld portable routers and router table setups, this patented four-cutter bit utilizes two up-shear cutters to clear primary stock and two down-shear cutters to slice surface fibers, delivering a splinter-free, hand-sanded profile finish across cabinet door borders, tabletop perimeters, and custom millwork.

Best Used For:

  • Architectural Cabinet & Furniture Edging: Milling a soft 5/16-inch radius rounded edge with a crisp inset bead profile along dining tables, cabinet stiles, and desk perimeters.
  • Guided Trim & Millwork Profiling: Tracing straight or curved workpiece perimeters using the integrated 3/8-inch pilot ball bearing to produce uniform decorative moldings.
  • Convertible Round-Over Profiling: Swapping the standard pilot bearing to convert the bit into a standard 5/16-inch radius round-over tool for square corner softening.

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 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 1-1/8-inch diameter profile cuts.
  • Integrated 3/8-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 18,000 RPM.

Pro-Tip: When routing 1-1/8 inch wide Quadra-Cut beading profiles in dense hardwoods, adjust your router speed to a maximum of 18,000 RPM to avoid friction burning. Take two shallow passes rather than a single heavy cut, allowing the down-shear wings on the final pass to glide over the top corner for an ultra-clean inset bead finish that requires zero hand sanding.
