Nah, that's only 60ipm. Rapid traverse on my machine happens to also be the maximum feed rate of 99 ipm.
My point with this isn't to show how fast my machine goes, but to show how to arrive at the recommended speeds and feeds. You can always back it down from there, but when you do I think the most important thing is to keep the carbide doing some work in feed per tooth. As soon as you back off on feed rate, you'll rub the insert to death.
If concerned about chips flying and wearing out inserts, lower the cutting speed and just keep the feed rate commensurate. Don't go too low on cutting speed, you'll break the carbide. However, once you get down to 100 surface feet per minute, why bother with carbide insert tools? You might as well wear out some HSS.
P.S. - This cutter works just SO much better than the Kennametal one it replaced it's ridiculous!
