"These cause it to become even harder the faster you grind or drill "due to interatomic forces between the ceramic grains," and "the force and energy of the disc or the drill is turned back on itself, and it is weakened and destroyed by its own attack."

So what happens if you cut or drill at low speed?

Same damage done on the upper layer to the cutting device. Just takes much longer to wear down - the only way you make any slight cut into it is with high speeds
