Freud Rounding Over Router Bit 85-342 1/4 Inch Radius (Solid Surface Edge Finishing Non Marring Bearing 1/2 Inch Shank 24000 RPM Handheld Router)

Freud 85-342 1/4-Inch Radius Solid Surface Rounding Over Router Bit

The Freud 85-342 1/4-Inch Radius Solid Surface Rounding Over Router Bit is an edge-shaping woodworking tool engineered to rout a 1/4-inch radius top edge on solid surface countertops, custom cabinets, and millwork. Operating at rotational speeds up to 24,000 RPM with a 1/2-inch shank, 3/8-inch carbide height, and 2-3/8-inch overall length, this 1-inch diameter dual-flute bit utilizes TiCo hi-density carbide cutters and a non-marring synthetic pilot guide bearing. Designed for handheld portable routers, this edge-finishing bit solves edge chipping, surface scratching, and sharp corner hazards across commercial Corian, Avonite, and composite acrylic fabrication installations.

Best Used For:

• Solid Surface Countertop Edge Rounding: Milling a smooth, 1/4-inch radius top profile along Corian and Avonite kitchen tops, vanity edges, and island borders.
• Full Bullnose Profile Assembly: Operating in tandem with a matching under-rounding bit to create a complete, smooth bullnose edge on composite slabs.
• Scratch-Free Handheld Edge Finishing: Gliding along finished composite faces on job sites using a non-marring synthetic bearing to prevent surface buffing rework.

Key Performance & Safety Features

• Precision 1/4-Inch Profile Radius: Shapes a uniform 1/4-inch radius to ease sharp corners and increase edge impact durability on solid tops.
• Non-Marring Synthetic Pilot Guide Bearing: Smooth polymer sleeve rides directly against finished composite edges to eliminate friction marks, scratches, and gouges.
• TiCo Hi-Density Micro-Grain Carbide: Formulated titanium-cobalt carbide composition resists thermal wear and maintains sharp cutting edges in abrasive acrylic resins.
• 24,000 RPM Maximum Rotational Speed: Dynamically balanced dual-cutter body delivers smooth, chatter-free edge cuts at high router spindle speeds.
• 1/2-Inch Heavy-Duty Steel Shank: Precision-ground round shank provides maximum clamping surface area in router collets to prevent bit slippage under load.
• Perma-SHIELD Thermal Non-Stick Coating: Protective red fluoropolymer coating prevents resin buildup, glue adhesion, and motor drag.

What's Included

• (1) Freud 85-342 1/4 in. Radius Solid Surface Rounding Over Router Bit (1/2 in. Shank)
• (1) Non-Marring Synthetic Pilot Guide Bearing (Pre-Installed)

Technical Specifications

Pro-Tip: Wipe down the solid surface edge before routing so dust particles do not get trapped under the synthetic bearing, ensuring a perfectly smooth 1/4-inch radius cut without micro-scratches.
