3-Flute Carbide-Tipped Juice Groove Router Bits, Cleaner Cutting Board Grooves with Chamfered Lead-in, Faster Feed Rates, Smoother Finish – CNC & Template Routing – Made in USA US2337JG

Ultra-Shear Carbide-Tipped 3-Flute Juice Groove Bits take cutting board projects to a new level of professionalism while saving time and effort. The 3-flute design gives you the option of more cuts per inch at the same feed rate or faster feed rates with no loss of finish quality. Each groove profile features a chamfered lead-in that transitions smoothly into the cove. This design simplifies sanding and improves juice flow by eliminating the sharp edge left by common ball-nose bits. All three profiles allow flexibility in appearance—you can cut shallow grooves that just break the edge or increase depth to create a wider chamfered accent. The set includes two full cove designs in 3/8" and 1/2" diameters with 30° chamfers, plus a third design featuring a 90° vee-groove with a 1/4" radius tip. Each style complements different cutting board shapes and design preferences. For handheld routing, the simplest method is an internal template and a template guide bushing. Ultra-Shear offers a special 1" diameter, 7/32" long guide bushing that fits Porter-Cable-style bases. Shape a 1/4" template, secure it with double-faced tape, and guide the bushing against the template edge—it’s fast and adaptable. These bits also work flawlessly in CNC machines of any size and with the Shaper Origin. Made in the USA.
