Well I know someone can help me. I was given a military storage box full for machining tools mostly tool bits reamers and odds and ends. Several endmills were wrapped in news paper and after sometime searching I found a date of 1973 on one of the wrappers from a town somewhere in Alaska. But this was also in this box of tools and if someone can tell me what it is called and what is is used for I would appreciate it.
