3M 7000045105 Roloc 361F Abrasive Disc 2 Inch P240 Grit

Product Description

The 3M 7000045105 is a 2-inch Roloc quick-change coated abrasive disc built for grinding, blending, deburring, and finishing on all metals. The disc uses fast-cutting aluminum oxide abrasive grains bonded to a heavyweight YF-weight polyester cloth backing with a heat-resistant resin. That resin bond holds up under pressure, elevated heat, and exposure to water, making this disc suitable for both wet and dry service. Rated at 20000 RPM, the disc installs and removes quickly via the Roloc attachment system, reducing downtime during high-volume finishing work. At P240 grit, it is appropriate for fine blending and finishing passes rather than aggressive stock removal.

This disc is designed for metal fabrication and finishing applications in light industrial and shop environments. Typical use cases include deburring cut edges, blending weld seams, and surface finishing on steel, aluminum, and other metals. The 2-inch diameter makes it well suited for tight-access areas and detail work on fabricated parts. It is commonly used with right-angle die grinders equipped with a compatible Roloc mandrel.

Installation Notes

Installation and removal are performed by a trained operator or technician using a compatible Roloc mandrel. Ensure the grinder is powered off and disconnected from the air or electrical supply before mounting or removing the disc. Confirm the tool RPM rating meets or exceeds the 20000 RPM maximum speed of this disc before operation. Inspect the disc for damage before each use and do not use a disc that shows cuts, tears, or delamination.
