At work a guy is reaming out a hole to a larger size in a frame rail
on a truck. His reamer starts squealing like a banshee. I say, "Hey,
how about a little cutting oil?"
He looked at me like I was an idiot and told me that it'll dull the
reamer and take chunks out of it in nothing flat. Everyone else in the
shop agreed. But nobody could explain to me how or why, only that it
would happen.
So am I missing something here? I thought reaming required cutting
fluid, but now I hear from a whole crowd that does a fair amount of
reaming that it's just the opposite.
The reamer in question is basically 2743A14 at mcmaster.com Perhaps
these things follow a different set of rules?
Also, is it possible to salvage one of these once it's dull without
resorting to anything beyond hand tools?
