3M 7100045904 Abrasive Disc Roll 5 Inch 120 Grit

Product Description

The 3M 7100045904 is a coated abrasive disc roll featuring 3M Precision Shaped Ceramic Grain technology. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasives. This design delivers a disc that cuts up to 2x faster and lasts up to 4x longer than standard abrasive discs. At 5 inches in diameter and 120 grit, this disc roll is suited for aggressive stock removal on a range of substrates. The Stikiti attachment system allows for fast disc changes without removing individual liners.

This disc roll is designed for stock removal applications across a variety of substrates including metal, wood, and composites. The roll format eliminates the need to peel individual disc liners, making it practical for high-volume production or shop environments where turnaround speed matters. It is commonly used by fabricators, welders, and finishing technicians working with angle grinders and random orbital sanders equipped with a compatible Stikiti backup pad.
