I keep hearing that if you have to use a file on the lathe, its best to use a 'mill file'. Maybe I buggered that up - are they called lathe files? Anyway, the difference to a conventional file is described as the cut lines are at a shallower angle relative to the file edge. Makes sense to me, I'd like to try some. But I have not seen them available in many typical machinery supply outlets. Any leads or recommendations? Disclosure: Not that I'm looking to spend extra money, but I am now a self-confessed file snob. After years of buying typical 'brand name' hand files I tried a few Swiss files. OMG they cut & finish so nice, its like night & day.
