3M 7010363161 Flap Disc 577F 4.5 Inch 36 Grit Quick Change

Product Description

The 3M 7010363161 is an alumina zirconia flap disc in the 577F series, designed for high-pressure metalworking applications where grinding and blending must happen in a single pass. At 4.5 inches in diameter with a 36-grit cut, it removes material aggressively while leaving a blended finish behind. The abrasive mineral includes a grinding aid that delivers more cutting power than standard aluminum oxide across all metal types. Heavyweight polyester-backed flaps support demanding tasks such as weld removal, sharp-edge work, and beveling. The quick-change mounting system reduces disc swap time on the tool.

This flap disc is suited for metal fabrication, structural steel work, and maintenance environments where operators need to remove welds, deburr edges, or prep surfaces without switching between separate grinding and blending discs. It is appropriate for use on steel, stainless steel, and other common metal substrates encountered in heavy-duty shop and field applications. Licensed metalworkers and fabricators are the primary installers and users of this product.

Installation Notes

Installation and operation of abrasive flap discs should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Verify that the tool's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Inspect the disc for damage before each use and never operate a damaged disc. Always use appropriate personal protective equipment including eye protection and gloves when grinding or blending.
