Freud 20-320 3/4 Inch Radius V Groove Router Bit 3/8 Inch Radius 1/4 Inch Shank CNC Decorative Carving Signmaking Fluting Perma-SHIELD

Add Elegant Detail and Fluting with Freud's Precision 3/8-Inch Radius V-Groove Bit

Transform ordinary woodworking projects into decorative masterpieces with the Freud 20-320 3/4-Inch Diameter Radius V-Groove Router Bit. This versatile tool is designed to cut smooth, rounded grooves that are perfect for creating intricate rosettes, fluted columns, and decorative veins in cabinet doors and millwork. Unlike standard V-groove bits that leave a sharp bottom, the 3/8-inch radius on this bit produces a soft, curved profile, adding a sophisticated touch to signs, spheres, and exposed joinery. It performs exceptionally well across a wide range of materials, including hardwood, softwood, plywood, composites, and plastics.

Engineered for professional durability, the 20-320 features Freud's exclusive TiCo Hi-Density Carbide, which ensures a razor-sharp edge that stays sharper longer than standard bits. The bit is fully encased in Freud's signature Red Perma-SHIELD® Non-Stick Coating, a high-performance thermal barrier that prevents heat buildup, rust, and pitch accumulation—critical factors when routing deep decorative grooves. With a standard 1/4-inch shank, this bit provides stable, chatter-free operation in CNC machines, as well as hand-held and table-mounted routers, delivering a flawless finish every time.
