3M 7000119468 Flap Disc 577F 7 Inch 36 Grit

Product Description

The 3M 7000119468 is the 577F alumina zirconia flap disc, a coated abrasive tool engineered for high-pressure metalworking. Measuring 7 inches in diameter and carrying a 36-grit rating, this disc combines grinding and blending into a single operation. The abrasive mineral is alumina zirconia with an integrated grinding aid, which delivers faster stock removal than standard aluminum oxide across steel, stainless, and other common metal types. Heavyweight polyester-backed flaps provide the structural rigidity needed for demanding tasks without premature wear. Licensed metalworking professionals and fabrication shop technicians are the primary installers and end users.

The 577F flap disc is suited to heavy-duty metal fabrication tasks including weld removal, sharp-edge cleanup, and beveling on structural and sheet metal work. Its flap design allows the operator to grind and blend in one pass, reducing total labor time on each joint or surface. The 36-grit specification makes it appropriate for aggressive material removal where surface finish requirements allow coarser results. It is sold and rated as an individual unit.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all common metal types
• 36-grit rating provides aggressive stock removal for weld removal and beveling
• Heavyweight polyester-backed flaps deliver extended life under high-pressure grinding conditions
• Combined grinding and blending action reduces process steps and saves labor time
• 7-inch diameter fits standard angle grinder backing pads of matching size

Compatibility

Designed as a coated abrasive flap disc replacement for 7-inch angle grinders used in metal fabrication, weld preparation, and finishing applications.

Installation Notes

Flap discs of this type are mounted and removed by grinding equipment operators following the grinder manufacturer's guard and flange requirements. Verify that the grinder's maximum rated RPM meets or exceeds the disc's rated speed before mounting. Power down and disconnect the grinder from its power source before changing discs. Eye protection, gloves, and appropriate respiratory PPE should be worn during operation per applicable OSHA and shop safety standards.
