Freud Bowl Router Bit 85-157 1/2 Inch Radius (Solid Surface Round Over Edge Trimming Non Marring Bearing 1/2 Inch Shank Sink Fabrication)

Freud 85-157 1/2-Inch Radius Round Over Bowl Solid Surface Router Bit

The Freud 85-157 1/2-Inch Radius Round Over Bowl Solid Surface Router Bit is a specialty countertop fabrication tool engineered to rout smooth, rounded bowl transitions and decorative edge profiles in Corian, granite composites, and acrylic solid surface materials. Operating at rotational speeds up to 24,000 RPM with a 1/2-inch shank and a non-marring synthetic pilot bearing, this dual-flute carbide-tipped bit prevents surface scratches on finished composite sink basins. Designed for handheld portable routers, this round-over bowl bit solves sharp rim edges, surface buffing burns, and difficult sink-to-countertop transition challenges across custom kitchen and bath fabrication shops.

Best Used For:

• Solid Surface Sink Bowl Round-Over Edging: Milling a smooth, 1/2-inch radius transition along undermount kitchen sink rims and bowl interiors to eliminate sharp edges.
• Custom Composite Countertop Trim Finishing: Shaping decorative rounded edges on solid surface vanity tops, bar counters, and architectural millwork.
• Scratch-Free Handheld Template Routing: Guiding the router along finished composite surfaces using a non-marring synthetic bearing without leaving pilot burn marks.

Key Performance & Safety Features

• Non-Marring Synthetic Pilot Bearing: Polymer guide bearing glides smoothly against finished acrylic sink basin walls to prevent abrasive scratching and marring.
• Precision 1/2-Inch Radius Profile: Routs a smooth 1/2-inch rounded edge radius to enhance tactile comfort and impact resistance on solid composite tops.
• Solid-Surface Formulated Carbide Cutters: High-density micrograin carbide edges resist thermal degradation from abrasive synthetic minerals and resins.
• Heavy-Duty 1/2-Inch Steel Shank Core: Rigid shank diameter increases stability and neutralizes bit flexing during deep manual feed routing passes.
• 24,000 RPM Maximum Speed Rating: Dynamically balanced dual-cutter body delivers clean, burn-free finishes at high spindle speeds.

Technical Specifications

Pro-Tip: Keep the non-marring synthetic bearing clean and free of acrylic dust build-up during sink bowl profiling to ensure the bearing rolls smoothly without leaving friction marks on the basin wall.
