Freud 18-522 3/4 Inch Top Bearing Round Nose Core Box Router Bit

The Freud 18-522 is a 3/4-inch overall diameter top-bearing round nose core box router bit engineered to rout deep 3/8-inch radius U-grooves, fluted millwork channels, and template-guided sign lettering. Built with a 1/2-inch shank and an integrated shank-mounted top bearing, this 2-cutter tool follows overhead templates and pattern guides to execute precise veining and fluting without chatter. Forged from Freud Premier Solid Carbide, it operates at speeds up to 24,000 RPM across solid hardwoods, softwoods, plywood, and composites in CNC machinery, handheld routers, or router tables.

Best Used For:

• Template-Guided Sign Lettering & Veining: Routing precise 3/8-inch radius round-bottom letters and decorative face channels using overhead templates.
• Fluted Architectural Millwork: Milling parallel U-shaped decorative flutes on fireplace mantels, pilasters, and cabinet door stiles.
• Juice Groove & Tray Milling: Carving smooth perimeter juice channels and recessed grooves into hardwood cutting boards and serving platters.

Technical Specifications

Pro-Tip: Ensure your top template pattern thickness is at least 1/4 inch high so the top bearing makes full, flush contact with the template edge before lowering the spinning carbide cutter into the workpiece.
