I used this well made 5/8 inch radius door hinge groove cutter when I had the job of replacing it over 20 doors (different in appearance than existing ones) in existing door jambs in residential buildings. The customer was happy with the doors and I was happy with the performance of the 1 1/4" router bit. I made a door edge jig which made it easy to perfectly duplicate the desired size and depth of the mortise locks.
