Being a hobby user I use just about any materials at hand, some good some really horrible and have found that the biggest difference is flood coolant and climb milling.
I do try to use highish feed rates.
Mostly carbide tools, some of which are totally inappropriate, 4 or even 6 flute, and the only problems I've had have been when the coolant ran low and stopped, instant clogging and a snapped 10mm carbide bit.
Now that was a loud bang!
