Freud Router Bit 85-115 3-1/8 Inch (Solid Surface Edge Profile Drainboard Grooving Micrograin Carbide 1/2 Inch Shank 24000 RPM Handheld Routing)

Freud 85-115 3-1/8-Inch Solid Surface Edge Profile Drainboard Grooving Router Bit

The Freud 85-115 3-1/8-Inch Solid Surface Edge Profile Drainboard Grooving Router Bit is an industrial composite fabrication cutter engineered to rout sloped, water-channeling drainboard flutes and decorative edge profiles in solid surface countertops. Operating at rotational speeds up to 24,000 RPM with a 1/2-inch shank and 3-1/8-inch overall diameter, this dual-flute bit utilizes specially formulated micrograin industrial carbide cutters and a Perma-SHIELD non-stick thermal coating. Designed for handheld portable plunge routers, this large-diameter profiling bit solves water pooling, material chipping, and surface scorching challenges across commercial Corian, Avonite, and composite acrylic installations.

Best Used For:

• Solid Surface Drainboard Water Run-Off Flutes: Milling sloped, 3-1/8-inch wide flat-bottom drainage channels adjacent to undermount kitchen sinks in acrylic composite countertops.
• Architectural Edge & Trim Profiling: Shaping uniform, decorative edge profiles along solid surface vanity tops, commercial reception desks, and wet bar installations.
• Template-Guided Plunge Routing: Executing controlled, chatter-free channel passes using sloped straightedge jigs and handheld 1/2-inch collet routers.

Key Performance & Safety Features

• Specialized Drainboard Profiling Geometry: Precision-ground cutters mill a smooth, flat-bottom channel bounded by 1/8-inch radius shoulders for optimal liquid runoff.
• Micrograin Industrial Carbide Formulation: High-density carbide cutters resist severe abrasive wear from synthetic minerals and non-porous acrylic resins.
• Heavy-Duty 1/2-Inch Steel Shank Core: Rigid 1/2-inch shank absorbs chatter and neutralizes bit flexing under heavy material passes in portable routers.
• 24,000 RPM High-Speed Velocity Rating: Precision-balanced dual-wing cutter body delivers clean, burn-free finishes requiring minimal post-rout polishing.
• Perma-SHIELD Non-Stick Thermal Coating: Protective red coating reduces cutter drag, prevents pitch adhesion, and dissipates heat buildup.

Technical Specifications

Pro-Tip: Secure a sloped wooden routing ramp to the countertop slab so the handheld plunge router descends incrementally toward the sink cutout for precise, gravity-fed drainboard grooves.
