It kinda got me thinking about the largest actual cutting toolbits that
have ever been used. There was a discussion a while back about the
largest single block of steel people had ever seen...what about the
largest tooling (not machine) used to cut these kind of things?

I'm sure I'm not in the running for the largest, but here's my 2 cents.


In the days when HSS, and cobolt reined, we used 2" diameter hog mills
pretty often.
