I have a hole that this bolt goes into.
The first part of the threads of the hole are damaged.
I want to chase the threads using my new tap/die set.
The gauge thingy says 1.25.
I've chased the threads of the old bolt with an M8 x 1.25 die and it seems to screw into the bottom of the hole OK.
Why do I feel like I'm chewing the fuck out of the hole when using a M8 x 1.25 tap?

Probably because the damaged threads in the end have caused the tap to start cutting threads off set.
Can you not start tapping from the other side of the hole?
