If you are going to be doing any composite cutting, I'd make sure you
use a diamond bit or blade. Carbide works, but diamond will still last
longer. Also, if possible use water when cutting, this keeps the blade
cool and will make it last longer, and keep the dust down. Wet tile
saws work great.

Be sure to wear a mask, carbon fiber can get nasty.
