Freud Solid Surface Bowl Router Bit 85-001 1/2 Inch Shank (2 Dia 1 Carbide Height 1/2 Radius 15 Deg Undermount Sink Countertop Trimmer)

Professional-Spec 1/2 Inch Shank 2 Inch Diameter Solid Surface Round Over Bowl Router Bit

The Freud 85-001 Round Over Bowl Router Bit functions as an architectural solid surface edge trimmer engineered to flush-cut countertop overhangs while shaping a 1/2-inch radius round-over profile along undermount sink bowls. Manufactured with micro-grain TiCo titanium cobalt carbide flutes formulated for abrasive composite materials, this 1/2-inch shank cutter operates on handheld portable routers at rotational speeds up to 16,000 RPM. The 2-inch overall diameter bit features a 1-inch carbide height, 15-degree cutting angle, and a conical non-marring synthetic pilot bearing to deliver smooth, burn-free transitions across Corian, Wilsonart, and Avonite fixtures without scratching bowl surfaces.

Best Used For:

• Undermount Sink Overhang Trimming: Flush-trimming solid surface countertop overhangs while applying a smooth 1/2-inch radius edge along undermount sink bowls.
• Seamless Counter-to-Bowl Transitions: Creating watertight, hygienic radiused joints between acrylic countertop slabs and solid surface sink basins.
• Non-Marring Handheld Routing: Guiding along pre-installed acrylic or composite sink bowls using portable routers without scorching or scratching finished surfaces.

Key Performance & Safety Features

• Dual-Action Trimming & Profiling: Trims overhang stock flush and applies a 1/2-inch round-over radius in a single continuous routing pass.
• Conical Non-Marring Pilot Bearing: Specialized synthetic bearing glides along polished sink bowl interiors without leaving friction marks, scratches, or burns.
• TiCo Micro-Grain Carbide Flutes: Custom titanium cobalt carbide formulation maintains edge sharpness against highly abrasive mineral-filled polymers.
• 15-Degree Shear Cutting Angle: Beveled cutter geometry reduces feed resistance, minimizes chatter, and produces a glass-smooth surface.
• High-Speed Balance Shank: Precision-machined 1/2-inch steel shank prevents cutter vibration during handheld routing up to 16,000 RPM.

Technical Specifications

Pro-Tip: Before routing, wipe down the inside rim of the undermount sink bowl with denatured alcohol to remove any residual joint adhesive or dust. A clean sink surface allows the synthetic conical bearing to roll freely without picking up abrasive particles that could scratch polished solid surface basins.
