3M™ Trizact™ Diamond HX Discs are used to restore and bring back the natural beauty of stone floors, simply by using standard floor cleaning equipment. These discs are faster than a traditional diamond grind and allow you to refurbish your own floors without the need for specialists. The discs consist of precisely-patterned, composite abrasive structures distributed uniformly on a flexible backing. As these structures wear, fresh, sharp diamond abrasive is continually exposed, resulting in uniform, consistent and fast cutting action through the life of the product. Dust-free cleaning process, which minimises sub-surface damage and can cut up to 85% off your costs.
