Is that laminate flooring hard on bits?

Cheap laminate flooring. It doesn't seem to hurt the bit too much. I have cut dozens of signs for the college similar in size and the bit (Harbor freight carbide classic Roman w/ 1/8" tip radius) is still working strong. My experience in the past with tooling is most problems with tooling is not matching proper feed with tool RPM. Almost impossible to do when cutting manually but a piece of cake if you do your math on a cnc.
