Also known as a \"Core Box\" bit, this precision tool features a 3\/16-inch radius, making it the perfect solution for cutting smooth, semi-circular grooves. It is exceptionally versatile, widely used for routing decorative flutes on millwork, adding classic accents to cabinet doors and drawer fronts, and engraving crisp, readable lettering for signs. Whether you are working with hardwood, softwood, plywood, or composites, this bit delivers a clean, polished finish that enhances the visual appeal of any piece.\u003c\/p\u003e\n\u003cp\u003eConstructed from Freud's Premier Solid Carbide, the 18-106 is engineered for maximum durability and edge retention. The solid carbide design provides superior rigidity, minimizing vibration and ensuring chatter-free cuts even at high RPMs. This makes it an ideal choice for the demanding feed rates of CNC machines, as well as the precision required in hand-held and table-mounted routers. With its ability to produce deep, clean grooves without burning, this bit is a staple for professional woodworkers and serious hobbyists alike.\u003c\/p\u003e\n\u003ch3 style=\"border-bottom: 1px solid #ddd; padding-bottom: 10px; margin-top: 30px;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"margin-bottom: 30px;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/16-Inch Radius Profile:\u003c\/strong\u003e Creates perfectly round 3\/8-inch wide grooves for fluting and veining.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremier Solid Carbide:\u003c\/strong\u003e Solid construction ensures superior hardness, sharp edge retention, and long life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Application:\u003c\/strong\u003e Ideal for sign lettering, decorative fluting, and finger pulls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Machine Compatibility:\u003c\/strong\u003e Engineered for use in CNC, automatic, hand-held, and table-mounted routers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Versatility:\u003c\/strong\u003e Cuts cleanly through hardwoods, softwoods, plywoods, and composite materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Balanced:\u003c\/strong\u003e Designed to run smoothly at high RPMs (up to 24,000) for a flawless finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Flute Design:\u003c\/strong\u003e Two cutting edges ensure efficient chip removal and smoother surfaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin-bottom: 30px;\"\u003e\n\u003cli\u003e(1) 3\/8\" Dia.
