3M 7000119477 Flap Disc 577F 7 Inch 36 Grit

Product Description

The 3M 7000119477 is the 577F alumina zirconia flap disc, a coated abrasive tool designed for high-pressure metalworking in fabrication and maintenance environments. The disc combines grinding and blending into a single step, reducing tool changes and overall labor time. Fast-cutting alumina zirconia mineral, enhanced with a grinding aid, delivers more aggressive stock removal than standard aluminum oxide across all metal types. Heavyweight polyester-backed flaps hold up under sustained pressure, making this disc a reliable choice for weld removal, beveling, and sharp-edge work. The 7-inch diameter disc runs at 36 grit for heavy material removal. Installation and disc changes are simplified by the quick-change design.

This flap disc is suited for metalworking applications in industrial, fabrication shop, and field maintenance settings. Typical uses include weld removal, beveling, and sharp-edge finishing on steel and other metals. The 36-grit cut rate makes it appropriate for aggressive stock removal passes before a finer finishing step, or as a standalone step where a blended surface finish meets the job requirement. Metalworkers, welders, and fabricators working with structural steel, plate, or pipe are the primary users.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide across all metal types
• Flaps combine grinding and blending in one step, reducing tool changes and labor
• Heavyweight polyester-backed flaps extend disc life on high-pressure applications
• Quick-change disc design simplifies changeover
• 7-inch diameter, 36-grit configuration targets heavy weld removal, beveling, and sharp-edge work

Compatibility

Designed as a direct-fit replacement flap disc for 7-inch angle grinders and compatible backing pads used in general metalworking and fabrication applications.

Installation Notes

Flap discs of this type are mounted and operated by metalworkers and fabricators using angle grinders rated for the disc diameter and RPM. Always confirm the grinder's rated speed meets or exceeds the disc's maximum RPM before mounting. Power down and disconnect the grinder before changing discs. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
