I am using this little internal turning tool I have gotten from some company long ago as it was too worn out for them to use. By the time i gotten it for me as hobbyist, it was stil good for me to do some simple turning. Now after some time I think it starts to wear out. I would like to buy a new one, but I cannot figure out what kind of internal turning tool this is. Perhaps some internal turning tool to make internal screw thread?
Can someone help me to identify what kind of tool this is and where it is used for so perhaps I can find a new one to buy. The thing itself is like 3cm so it is pretty small.
