Hoping for some ideas. I have a shotgun with a 3/32" diameter pin in a blind hole I need to remove.
The pin started out as a screw tha was threaded at one end and a pin at the other. Previous owner broke the screw head off. I was unable to drill it out as it is hardened. Harder than hss anyway.
I have plunge milled the head and threaded screw shaft with a 1/8" carbide end mill. Now I am down to just the pin part. It is about 1/4" long. My only 1/16" end mill won't reach any deeper and broke tonight anyway.
I am left with a .09375" pin .250" long in a blind hole. I have .125" diameter hole all the way down to the remaining pin. There is a start of a .0625" hole in the pin. It is not very deep and wandered off center slighty when the end mill broke.
Any ideas?
