Very abrasive stuff, the fiberglass. Perhaps a slower speed with as high of feed you can get without an ugly cut or end mill breakage. I suspect you will be going through quite a few end mills. Even with the best feed/speed combination, cutting glass is going to be hard on the tooling. What material is the end mill you used?

It goes a step further: particle size reduction. A pre-dispersed mixture that requires further particle size reduction is then transferred to a mill for processing. The mill components "attack" the particles using various mechanical forces: media, pegs, and screens, to achieve the particle breakdown.
