Achieve Seamless Sink Transitions with Professional Solid Surface Precision

Create a flawless, watertight transition between your solid surface countertop and undermount sink with the Freud 85-003 Round Over Bowl Router Bit. Designed for the exacting standards of professional fabricators, this tool specializes in trimming the countertop overhang flush with the sink bowl while simultaneously routing a smooth 1/2-inch radius round over profile. The result is a clean, continuous curve that eliminates dirt traps and provides a sleek, modern finish to kitchen and bathroom installations.

Engineered for performance on demanding materials like Corian®, Avonite®, and other composites, the 85-003 utilizes Freud’s exclusive TiCo™ Hi-Density Carbide. This specialized formulation resists the abrasive wear typical of solid surface fabrication, ensuring extended edge life and a superior finish quality. Critical to its design is the non-marring synthetic bearing, which rides gently along the sink bowl wall without scratching, burning, or leaving marks on the finished surface. Protected by Freud's red Perma-SHIELD® coating, this bit resists heat buildup and corrosion, making it the reliable choice for hand-held routing applications.

Key Features

  • Seamless Joint Trimming: Simultaneously trims the countertop flush to the sink bowl and creates a smooth 1/2" rounded edge.
  • Non-Marring Protection: Equipped with a specialized synthetic bearing that glides along the bowl without scratching or damaging the finish.
  • Solid Surface Specialized: Carbide geometry is optimized for cutting dense composites like Corian, Wilsonart, and Avonite.
  • Perma-SHIELD Coating: Non-stick red coating minimizes friction, prevents pitch buildup, and protects against rust.
  • Extended Tool Life: Features TiCo Hi-Density Carbide designed to withstand the abrasiveness of synthetic materials.
  • Hand-Held Optimized: Balanced and designed specifically for use in portable hand-held routers for on-site fabrication.

Pro-Tip: Solid surface materials can heat up quickly during routing. To prevent melting the synthetic bearing or burning the countertop edge, keep the router moving at a consistent pace. Do not pause in one spot, and ensure your router speed is set appropriately for the large 2-inch diameter of this bit.
