Match the bit to the hinge and template
The title lists a 29 mm cutter and 1/2-inch shank. The gallery drawing labels a 30 mm head height, 100 mm overall length and medium 12.7 mm shank. Compare the cutter diameter with the hinge cup or mortise drawing and confirm the shank against the holder. Test the depth on scrap with the actual hardware.
Before routing a hinge recess
- Compare the 29 mm cutter diameter with the hinge specification.
- Check the template opening and desired mortise depth.
- Confirm that the holder accepts the listed 1/2-inch shank.
- Clamp an offcut and route a shallow test recess.
- Check hinge seating before routing a finished door or frame.
Listing limits
The page does not list a compatible hinge model, template size or material-specific cutting settings. The drawing provides cutter dimensions but does not replace a fit check with the actual hardware. Confirm the holder and required mortise depth before use.
