The MULTICUT QUATTRO diamond blade has a special coating with industrial diamond flakes directly applied to the crown with the “VACUUM” technology. It can be the true definitive universal diamond disc, as it allows you to cut many different materials and largely replaces the abrasive disc. Just mount a single disc on the grinder and cut everything. It does not release dust during cutting, as happens with abrasive discs, this makes it even more useful and versatile.
