The moment I realized I was crashing my end mills all wrong

I've been running this Haas VF-2 at work for two years and always babied my feeds on aluminum because I thought aggressive cuts would snap my tools. Last week I watched a guy on the next machine bury a 3/4" end mill at 200 IPM into a 6061 block and his tool came out like new. How do you figure out the real limits of your machine without blowing up a spindle or wrecking a $100 tool?

My first aggressive cut on aluminum turned a $50 end mill into confetti in 0.3 seconds.

Man, it's like how you never learn the real limits of anything until you break something first.
