3M 7000045103 Roloc 361F Disc P120 Grit 1.5 Inch Ao

Product Description

The 3M 7000045103 is a Roloc 361F coated abrasive disc designed for grinding, blending, deburring, and finishing on all metals. Measuring 1.5 inches in diameter and rated at P120 grit, it uses fast-cutting aluminum oxide abrasive grains bonded to a heavyweight YF-weight polyester cloth backing with a heat-resistant resin system. The quick-change Roloc attachment mounts and releases in seconds, reducing downtime during high-volume metal fabrication work. Machinists, welders, and metal finishing technicians install this disc on compatible right-angle grinders and die grinders for consistent stock removal and surface prep.

This disc is suited for medium-pressure applications on ferrous and non-ferrous metals in both production shop and field service environments. Its heat-resistant resin bond and durable polyester backing allow use in wet or dry conditions, making it practical for operations where coolant or water is present. The P120 grit level targets fine blending, light deburring, and pre-finishing work where surface finish quality matters.
