The 3M Trizact Diamond HX Gold Disc (part number 27621) is a professional-grade diamond abrasive disc system designed for aggressive stone floor restoration. Each box contains 4 discs measuring 5 inches in diameter with NH (no hole) center configuration.

This disc system is engineered for more aggressive refurbishing of stone floors exhibiting apparent wear or damage from scratching, pitting, and surface degradation caused by ice melting chemicals, heavy traffic, pallet wear, or other mechanical damage. The Trizact construction features structured abrasive technology with diamond mineral for consistent, repeatable performance throughout the life of the disc. The gold color designation indicates a coarse grit level suited for the initial stages of stone floor restoration and reconditioning.

Designed for use with standard 5-inch floor machine drivers, these discs are commonly used by professional janitorial and stone care services to restore marble, granite, terrazzo, and other hard stone surfaces. The Trizact abrasive structure continuously exposes fresh mineral as the disc wears, delivering consistent cut rate and finish.
