Folding Miter V Groove Bit Set for Miter Fold Boxes, Signmaking, CNC, 2-pcs 1/4" + 1/2" SH, USA-Made USVGFM-2PC

Perfect mitered boxes in minutes—no jig required. The Ultra-Shear Folding Miter Bit gives you a lightning-fast way to craft elegant boxes from a single piece of wood—just four cuts and you’re ready for glue. Set your fence to the box’s finished height, run all four edges through, trim the corners with a chisel or hobby knife, and fold it up. For flawless results, make two passes: one near full depth and a second that leaves just the thinnest sliver at the apex for a clean, flexible hinge. You may have seen this done with standard V-groove bits, but those often leave a fuzzy, uneven hinge line. Ultra-Shear’s Folding Miter Bit fixes that with a precisely engineered flat-bottom profile—just a few thousandths of an inch wide—that eliminates fuzz and creates a crisp hinge line. The bit’s angle is slightly over 90°, so all six joints close perfectly every time. 1/2"" shank: Cuts miter fold joints in material up to 3/4"" thick.1/4"" shank: Ideal for smaller routers and material up to 1/2"" thick. Once you’ve folded your first perfect box, the creative options are endless: Add a hinged slab lid for a refined finish.Bookmatch two blanks to create a hinged dual box.Cut rabbets for a piston-fit lid and elevate your design. Fast, accurate, and beautifully clean, the Folding Miter Bit opens up new possibilities in boxmaking, giftware, and fine woodworking. American-made precision: Manufactured in Strongsville, Ohio using state-of-the-art CNC grinding equipment, premium carbide, and ultra-fine grinding wheels, every Ultra-Shear bit is crafted by skilled Northeast Ohio machinists to deliver professional performance at a competitive price.
