While sorting old metalworking books, I came across a photo in an old
school textbook that showed a large press frame being milled with an
endmill (yes, it was a true endmill) in a horizontal mill of some sort.
The endmill was about 10" diameter (as big across as the operator's
head) and at least 2 feet long, spiral flute.

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?

Koz,
The auto plants are full of 4-5-7' diameter cutters, inserted of course.
Gotta be 300 inserts or lots more per cutter.

When I was in shop class in college the instructor had a chip off a shaper
that he got at Westinghouse in Sunnyvale CA. What was remarkable about this
spiral of metal was that at first glance it looked like a coiled spring off
the front end a Chevy. That shaper must of had a whole lot of horsepower to
curl up such a chip.

If knowledge is power, and power corrupts, what does this say about the
Congress?

At boeing surplus in seattle, you can buy endmills by the pound. I
bought one as a souvenir that is about 10" long and about 1 1/4" shank.

I got one like that and use it as a mill to trim edges with. - Nice long surface
and just kiss the surface on the way by.

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.
