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.

Key Features

  • Radius Profile: 3/8-inch radius creates smooth round-over grooves, spheres, and rosettes.
  • Perma-SHIELD® Coating: Non-stick red coating resists heat, rust, and pitch buildup.
  • TiCo Hi-Density Carbide: Specially formulated carbide maximizes cutting life and finish quality.
  • Versatile Material Compatibility: Cuts cleanly through plywood, hardwoods, softwoods, plastics, and composites.
  • Multi-Machine Use: Designed for use on CNC, hand-held, and table-mounted routers.
  • Decorative Applications: Ideal for sign making, fluting, and architectural millwork.
  • 1/4-Inch Shank: Compatible with most trim routers and standard 1/4-inch collets.

What's Included:

  • (1) 3/4" Dia. Radius V-Groove Router Bit with 1/4" Shank (20-320)

Pro-Tip: This bit is excellent for creating fluted pilasters or columns. To get the best finish without burning the wood, especially at the "bottom" of the radius where cutter speed is slowest, make the cut in multiple shallow passes rather than one deep plunge. This allows the chips to clear and keeps the carbide cool.

Well Made, Runs A Little Small
I bought this on short notice for a drag show. I wasn't expecting a whole lot, but it exceeded my expectations in a lot of ways. The interior feels like the inside of a standard suit coat, and is comfortable for long term wear. The sequins are sewn on in a pattern, and there's little, if any, fallout. I've only found a couple sequins on the floor. I've used it a lot since the drag show, for a lot of things (live streams, videos, etc). Absolutely worth the price, and I've already gotten my money's worth out of it. It does run a little small, but it still mostly fits according to the size chart. A few notes: - It doesn't have button holes, so if you're looking for something that buttons up, look elsewhere. - Washing instructions say to machine wash cool, warm iron (do not tumble dry, do not dry clean). I'd say run it on the gentlest cycle you can muster, or just spot clean stains and the pits (if you're sweaty). I don't know how well this thing would survive a wash, but I haven't needed to wash it yet.

Showstopper
We got so many compliments on our outfits. I wore this for our Daddy/Daughter dance and plan to take it on a cruise later this year. The jacket is great quality and a little on the heavy side with all the sequins. It fit perfect in the shoulders and chest. It was a little long on the sleeves for my taste but I just tucked them under and managed for the night. For reference I’m 5’10” tall and 175lbs with athletic build. I bought a large.

Missing Sequins and Threadbare!
Size: 3X-Large, Color: Purple, Size: 3X-Large, Color: Purple
Jacket is great for fit, and is overall okay, but there are large patches where no sequins are attached! For the $59.99 price I paid, I am definitely feeling very disappointed in the quality of the jacket. Of course, I didn’t realize this till after the return window closed! If you order, do yourself the favor and check to make sure the jacket is in good quality!
