Description

Create Massive Soft Curves with the Freud 34-140 1-1/2" Radius Rounding Over Bit

Transform substantial furniture pieces and architectural millwork with the Freud 34-140 Rounding Over Bit. This massive router bit features a sweeping 1-1/2 inch radius, making it indispensable for softening sharp edges on large projects like stair treads, heavy countertops, and conference tables. By eliminating harsh corners, you not only improve the comfort and safety of your furniture but also add a sophisticated, finished look that defines professional craftsmanship. Designed for serious stock removal, this bit allows you to create consistent, smooth bullnose profiles on hardwood, softwood, plywood, and composites.

Performance is paramount with a bit of this size, which is why the 34-140 utilizes Freud’s patented Quadra-Cut™ 4-cutter design. While standard bits use two cutting wings, Quadra-Cut employs four—two large wings that shear upward and two smaller wings that shear downward. This opposing shear action slices through wood fibers cleanly, virtually eliminating cross-grain tear-out and requiring minimal sanding. Protected by Freud’s Perma-SHIELD® coating to resist heat and pitch build-up, this heavy-duty tool is engineered to run cooler and last longer, even during rigorous use.

Key Features

  • Massive Edge Forming: Creates a large 1-1/2" radius curve, perfect for stair treads, counters, and thick furniture tops.
  • Quadra-Cut Technology: Advanced 4-cutter design (2+2) ensures a glass-smooth finish with no splintering or fuzz.
  • Versatile Application: Ideal for milling moldings, doors, drawers, and softening sharp edges on all wood types.
  • Industrial Durability: Features TiCo™ Hi-Density Carbide for maximum cutting life and edge retention.
  • Perma-SHIELD® Coating: Non-stick coating reduces friction, heat, and resin accumulation.
  • Convertible Profile: Swap the bearing for a smaller diameter (sold separately) to create a decorative beading profile.

Pro-Tip: This is a very large diameter bit (3-1/2"). For safety and the best quality finish, you must reduce your router's speed to 12,000 RPM or less. Do not attempt to cut the full 1-1/2" radius in a single pass; use the router table fence to step the cut out, taking 3 or more lighter passes to reach the final depth.
