Man, I spent many hours making a part and then when I was tapping it manually, the tap broke with a lot stuck in and not a lot sticking out to unthread it.
How do you remove taps?
Heat it up then try unthread it?
People have fancy methods like using EDM but I dont have that. The tap I believe is hardened carbon steel with titanium nitride coating. Presumably I can run a carbide end mill right down the center as its harder to cut it out. The problem also is the tap is super small. I dont think I have any carbide end mills that size, let alone that size to throw out.
Any tricks?
