Description

Achieve a Flawless, Sand-Free Finish with Freud’s Patented Quadra-Cut Technology

The Freud 34-138 1-3/8" Radius Rounding Over Router Bit is a shop essential designed for woodworkers who demand perfection in decorative edging. Featuring Freud’s patented Quadra-Cut™ 4-cutter design, this bit uses two large cutters that shear upward and two smaller cutters that shear downward to remove material with unparalleled precision. This unique 2+2 cutting geometry eliminates tear-out and "fuzzing," delivering a glass-smooth finish even in difficult cross-grain applications. Whether you are crafting intricate moldings, rounding over heavy table edges, or softening furniture corners, this bit ensures a professional result that requires virtually no rework or sanding.

Engineered for maximum durability, the 34-138 is constructed with TiCo™ Hi-Density Carbide and protected by a non-stick Perma-SHIELD® Coating. This red industrial coating reduces blade drag and prevents the heat and resin buildup that can lead to wood burning and premature tool wear. For added versatility, you can transform this rounding-over profile into a decorative beading profile by simply installing a 1/8" smaller diameter bearing. Designed for use in CNC machines, table-mounted routers, and hand-held units, this bit effortlessly handles solid hardwoods, softwoods, plywood, and abrasive composites.

Key Features

  • Quadra-Cut™ Design: Four cutting edges (2 up-shear and 2 down-shear) provide a splinter-free finish with no rework required.
  • TiCo™ Hi-Density Carbide: Specially formulated titanium-cobalt carbide maximizes tool life and sharpness.
  • Perma-SHIELD® Coating: Non-stick red coating protects against heat, corrosion, and pitch buildup.
  • Beading Versatility: Can be converted to a beading bit with a smaller bearing (sold separately) for dual-profile utility.
  • Vibration-Free Operation: Individually computer-balanced to ensure smooth, precise routing at high speeds.
  • Universal Machine Use: Optimized for high performance in CNC, hand-held, and table-mounted routers.

Pro-Tip: Because of the large diameter and weight of this 1-3/8" radius bit, always use it at a lower speed (maximum 12,000 RPM) to maintain safety and prevent vibration. For the smoothest possible finish on large radii, take two or three progressively deeper passes rather than removing all the material at once.
