Actually, if anything, these days the speed/feed charts are considered "safe starting points", and the actual speeds and feeds used are significantly higher. I personally have run 4" face mills at over 2500 SFPM, slabbing off 3/8" of aluminum in full passes..

Must be nice :) If I tried to remove 3/8" of aluminum at one go - with anything - on my machine, it would go from 2500 SFPM to Zero in a startling-fast period of time.

But, point taken. I'll edit the post to say "maximum safe starting point." After all, no one publishes a table of minimum speeds ;)
