These premium discs are made of micron-grade aluminum oxide which is electrostatically applied to the resin bonding on a flexible plastic backing. These are our longest lasting discs, with grit evenly dispersed for smooth cutting. The micron grading dramatically narrows the grit size variance for faster cutting. Measure 7/8" diameter.
