End mill life depends on several things..generally speaking the more aggressive cuts you take will stress the blade and we at it down faster.. I usually tell my students not to take more than 25% of the diameter of the bit at a time no matter the material.

I have yet to make any cuts with my mpcnc, but I do have a denford mill in my classroom. 1/8″ end Mills usually get about 30-50 hours of use… but we mill everything from aluminum to acrylic.
