CARBIDE TIPPED HINGE MORTISING BIT
Ultra-Shear Carbide-Tipped Hinge Mortising Bits cut mortises for hinges (and other inlaid hardware) with minimal fuss and professional results. Three sizes – 1/2", 3/4" and 1-1/4" – deliver one-pass cuts on everything from entry doors to jewelry boxes.
Each size is available with or without a bearing. If you're using a door jig system that relies on template guide bushings, choose the bits without bearings and continue using the guide bushings you already have.
If you don’t have a commercial template system, the bearing-guided bits simplify the process by eliminating the offset calculations required with guide bushings. Just make a simple shop-built template that exactly matches the hardware you’re installing. The bearing follows the template. The cutter mirrors the bearing. The mortise fits.

American Made Quality at Factory Direct Pricing
The 1/2" bearing-guided bit includes two bearings. One matches the cutting diameter, as expected. The second – a 5/8" bearing paired with the 1/2" cutter – matches the specifications of several popular commercial hinge template systems. You can upgrade to Ultra-Shear’s superior cutting geometry while continuing to use the jigs and templates you already own. In some cases, you can ditch the template guide bushing you're using now and use the bearing, instead.
All six bits feature down-shear cutting geometry, producing clean, crisp mortise edges — even in pre-finished doors and paper-thin veneers. No lifted fibers. No chipped edges.
Don’t settle for inferior quality imported bits. Ultra-Shear uses state-of-the-art CNC grinding equipment, the highest quality carbide, ultra-fine grinding wheels and skilled Northeast Ohio machinists to produce American-made router bits at extremely competitive prices.
The days of paying extra for middleman markups are over. Buy direct from the manufacturer and pocket the savings. We’re confident you won’t find American-made Hinge Mortising Bits of the same design for less — but this week you can save even more.
