3M 7010308901 Flap Disc 577F 7 Inch 80 Grit

Product Description

The 3M 7010308901 is a Type 29 flap disc in the 577F series, designed for high-pressure metalworking tasks including weld removal, beveling, and sharp-edge finishing. It uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster stock removal than standard aluminum oxide abrasives. At 7 inches in diameter and 80 grit, this disc grinds and blends in a single pass, reducing the number of steps in a typical metal finishing workflow. Weighing 0.84 pounds, it is sized for standard angle grinders used in fabrication and maintenance environments.

This flap disc is suited for ferrous and non-ferrous metal applications in both shop and field settings. It performs on structural steel, weld seams, and beveled edges where consistent material removal and a blended surface finish are required in one operation. Licensed metalworkers, fabricators, and ironworkers handling heavy-duty grinding tasks will find this disc appropriate for production-level use. A quick-change design reduces downtime during disc swaps on the tool.

Installation Notes

This disc is installed and serviced by metalworkers, fabricators, or maintenance technicians using compatible angle grinders rated for 7-inch accessories. Verify the grinder RPM rating meets or exceeds the disc RPM rating before mounting. Ensure the grinder is powered off and unplugged before changing discs. Always use the appropriate guard and personal protective equipment per ANSI B11 and tool manufacturer guidelines when operating grinding discs.
