[QUOTE="Kam Yu, post: 298702, member: 11735"] My tech used white wheels. She would get those white half moon cracks where the sprue was. I changed her fine diamond burs and those pear shaped green state burs for final smoothing (from vacalon). No more cracks. I think you can use almost anything but you will have to be more careful about generating heat. [/QUOTE]
