3M 7010363162 Flap Disc 577F 4.5 in 80 Grit Quick Change

Product Description

The 3M 7010363162 is a Type 27 coated abrasive flap disc designed for high-pressure metalworking in fabrication and industrial environments. Built under the 577F series, it features alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster material removal than standard aluminum oxide discs. At 4.5 inches in diameter and 80 grit, it handles aggressive stock removal while simultaneously leaving a blended finish. The quick-change attachment system allows tool-free disc swaps, reducing downtime on the job. This disc is installed and used by metal fabricators, welders, and industrial maintenance technicians.

The 7010363162 is suited for heavy-duty metalworking applications including weld removal, beveling, and sharp-edge finishing on structural steel, stainless steel, and other metal substrates. Because it combines grinding and blending into a single pass, it reduces the need to switch between multiple abrasive products during fabrication work. It is sold in a minimum quantity of 10 units per order and is intended for professional shop and field use where consistent cut rate and finish quality are required.

Key Features

• Alumina zirconia mineral with grinding aid for higher cut rate than aluminum oxide across all metal types
• Heavyweight polyester-backed flaps extend disc life under sustained high-pressure use
• Combines grinding and surface blending in a single step, reducing total abrasive count per job
• Quick-change attachment system simplifies and speeds disc replacement
• Effective on weld removal, beveling, and sharp-edge work

Compatibility

Designed for use with quick-change right-angle grinders and compatible angle grinder backing pads that accept 4.5-inch Type 27 flap discs.

Installation Notes

Installation is performed by welders and metal fabricators using compatible right-angle grinders. Ensure the grinder is fully powered off and unplugged before mounting or removing any abrasive disc. Verify that the grinder RPM rating meets or exceeds the maximum rated speed of the disc before operation. Always install and operate the disc with the appropriate guard in place per ANSI B7.1 and applicable OSHA standards.
