Dian Fong high quality tungsten carbide milling dental bur, used for zirconia, porcelain, wax, pmma.
1. DLC coated, this is the most commonly used type, it can be used on zirconium and wax.
as our experience, one DLC bur assembled on Roland system to mill Upcerama block can finish 90 to 130 teeth.
but for wieland's zircona block, it's harder than upcerama, so the life become a little shorter, ranges from 75 to 110 teeth.
