Built by Freud/Diablo, this 1/2" radius under rounding bit is designed to pair seamlessly with a matching Freud Rounding Over bit to deliver a flawless bullnose edge on your projects.

Engineered for handheld routers, this bit excels on solid surface materials, woods, laminates, and other substrates you encounter in cabinetry, furniture, and decorative trim. The carbide-tipped cutting edges provide lasting sharpness for repeatable, clean cuts from project to project, reducing tear-out and delivering a consistent radius every time.

Key advantages

• Precise 1/2" radius creates a bold yet refined bullnose edge that enhances drawers, tabletops, and cabinet doors.
• Pairing capability works with a Freud Rounding Over bit to achieve a complete bullnose profile in a single workflow.
• Durable carbide edges hold their sharpness longer, delivering smooth cuts through solid surface materials and engineered woods.
