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.
  • Double Flute Design: Two cutting edges ensure efficient chip removal and smoother surfaces.

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.

Older flash drives might not work.
Port labels are too faint to read easily and the PD out port isn't labelled (I suppose they thought it was obvious since it has a fixed cable). The USB ports are speedy except it won't recognize any of my several SanDisk Cruzer Glides. Others flash drives work okay. Works great as an iPhone USB C to TV HDMI converter.

Works as intended
I've been into emulators lately and this is a great HDMI out with charging capabilities to go with your high speed charging brick. Doesn't work for everything, but I can attest it works with the AYN Thor and a Google Pixel 8 Pro, and presumably higher end Pixels. Both have emulators and both come thru my TV just fine. Also works with Kodi. I tried to use wired controllers, but quickly figured I'm better off going Bluetooth on that route. I haven't tried file transfer or anything because all that mattered to me was getting it to the big screen. I'd rather have a docking stand for my needs, but freedom and flexibility isn't a bad thing for this device at a decent price and cheaper than a dock.

Versatile hub adds the ports my Mac lacks
This 7-in-1 USB C hub from Anker has made it easy to connect my laptop to all the devices I need. The HDMI port consistently outputs 4K video at 60Hz, while the USB 3.0 ports and SD/microSD slots transfer files quickly without errors. I appreciate that the pass-through charging allows me to power my MacBook while using the hub, and the unit itself feels solid and well made. It's truly plug-and-play, with no drivers to install, and it greatly expands the limited port selection on modern laptops. The only minor drawback is that the hub can get a little warm under heavy use, but overall it's a reliable, convenient accessory that I feel confident recommending.

Awesome USB-C Hub
My new MacBook Air has USB-C ports only, so I recently upgraded to this USB-C hub, a 7in1 Multi-Port USB-C Adapter, and it has completely solved all of my port needs. With the two USB-A ports, I can still use my old memory sticks, without replacing them, as well as two USB-C ports, all making moving files, movies and pictures, with ease. I needed something fast and reliability, and this little device delivers on both fronts. One of the USB-C ports it a power passthrough, which works great for charging device, like my MacBook Air. It is very easy to use, just plug and play, making it compatible with the MacBook Air. Also has a built in card reader, and a HDMI port, pretty much covering all your port needs. If you are looking for a well built, reliable, fast, and compact USB-C hub that can everything, this is the one to get. Highly recommended!

Good value and best of all - it works
This did the job I wanted it to. Expanded the ports when my laptop just ran out. No delay or ANY issue no matter what I plugged where and after a little figuring out where things went (not difficult) its performing very well. As far as value, its great. I always evaluate something by if I would purchase it again. Yes I would. if you need it, get it and set it up and move on with less worry about port capacity.
