How do you mortise a hinge with a dremel?
To mortise a hinge with a Dremel, first outline the hinge's shape on the door jamb or edge. Use a Dremel with a routing bit (like a 1/8-inch or 1/4-inch straight bit) to carefully rout out the outlined area to the hinge's depth. Work slowly, making multiple shallow passes for a clean, precise mortise.
