Create Intricate Flutes and Professional Signage with Freud's Solid Carbide Core Box Bit

Add sophisticated detail to your woodworking projects with the Freud 18-106 3/8-Inch Diameter Round Nose Router Bit. 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.

Constructed 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.

Key Features

  • 3/16-Inch Radius Profile: Creates perfectly round 3/8-inch wide grooves for fluting and veining.
  • Premier Solid Carbide: Solid construction ensures superior hardness, sharp edge retention, and long life.
  • Versatile Application: Ideal for sign lettering, decorative fluting, and finger pulls.
  • Multi-Machine Compatibility: Engineered for use in CNC, automatic, hand-held, and table-mounted routers.
  • Material Versatility: Cuts cleanly through hardwoods, softwoods, plywoods, and composite materials.
  • Precision Balanced: Designed to run smoothly at high RPMs (up to 24,000) for a flawless finish.

Pro-Tip: When using a core box bit to create drain grooves (for example, on a cutting board), use a plunge router and ramp into the cut gradually. To prevent burning at the bottom of the groove where the bit velocity is effectively zero, keep the router moving at a consistent pace and avoid pausing in one spot.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
