3M 7000119470 Flap Disc 577F 4.5 Inch 80 Grit Quick Change

Product Description

The 3M 7000119470 is a coated abrasive flap disc in the 577F series, designed for high-pressure metalworking applications where both grinding and blending are required in a single pass. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, this disc delivers faster cutting action and longer service life compared to standard aluminum oxide discs. At 4.5 inches in diameter and 80 grit, it is well suited for aggressive stock removal with a controlled surface finish. The quick-change attachment system reduces downtime during disc swaps. Licensed metalworkers and fabricators are the primary installers and users.

The 577F flap disc is used across a wide range of metal fabrication tasks including weld removal, sharp-edge work, and beveling on structural steel, stainless steel, and other ferrous and non-ferrous metals. The 80 grit rating positions it for moderate to heavy material removal while still leaving a blended finish without a secondary operation. It is suitable for use in both production shop environments and field fabrication settings where a single abrasive tool needs to handle multiple surface prep steps efficiently.

• 4.5 inch diameter and 80 grit rating suited for weld removal, beveling, and sharp-edge work

Compatibility

Designed for use with quick-change angle grinder systems accepting 4.5 inch flap discs. Suitable for metalworking applications on ferrous and non-ferrous metals.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the angle grinder manufacturer's guidelines and applicable ANSI B7 safety standards for abrasive wheels. Always power down and disconnect the grinder before mounting or removing the disc. Inspect the disc for damage before each use and confirm the tool's maximum RPM rating meets or exceeds the disc rating. Appropriate PPE including eye protection and gloves is required during operation.
