3M 7010308896 Flap Disc 577F 4.5 Inch 80 Grit Type 27

Product Description

The 3M 7010308896 is the 577F alumina zirconia flap disc, a coated abrasive tool engineered for high-pressure metalworking applications. It combines grinding and blending into a single pass, removing the need to switch between discs mid-job. The disc uses alumina zirconia mineral with a grinding aid for faster stock removal compared to standard aluminum oxide. Heavyweight polyester-backed flaps extend service life under demanding conditions. At 4.5 inches in diameter with an 80 grit rating, it runs at a maximum of 13300 RPM and is built for use in weld removal, sharp-edge work, and beveling operations.

This flap disc is suited for heavy-duty metalworking in fabrication shops, structural steel work, and maintenance environments. Its Type 27 flat profile makes it effective on flat surfaces and inside corners. Applications include weld seam blending, edge deburring, and surface conditioning on carbon steel, stainless steel, and other metals. The quick-change design reduces downtime between disc swaps, which is useful in high-volume production settings. Installers and fabricators working with angle grinders will find this disc a direct fit for standard 4.5-inch tool heads.

Installation Notes

This disc is installed and serviced by metalworkers and fabricators using angle grinders. Before mounting, verify the grinder is unplugged or the power source is locked out. Confirm the tool's RPM rating meets or exceeds the disc's 13300 RPM maximum before operation. Always use the appropriate guard and personal protective equipment as required by applicable safety standards.
