My interest wasn't for roughing however, I like the near full circle of
the body. These are very well balanced. Ran the big one up to 3400 rpm
and no noticeable vibration at all. Sure wouldn't try that with the type
that use brazed lathe bits!

I regularly run my Bridgeport @ 4200 RPM with that setup. No problem.
Even with the tool extended somewhat.
