I am repairing the hangers of several pieces of artwork which are mounted on 1/2 inch MDF. They are hung to the wall using a dry wall screw which fits into a dovetail slot in the MDF. The dovetail is about 25 degrees (for each side). The diameter at the bottom of the dovetail slot is 2/8 inch. It is about 1/4 inch deep.
I have not be able to find such a router bit on the internet.
Any suggestions would be greatly appreciated.
Thanks,
Dale
