3M 7010363152 Flap Disc 577F 36 Grit 7 Inch Type 27

Product Description

The 3M 7010363152 is a Type 27 quick-change flap disc in the 577F series, designed for high-pressure metalworking applications. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, it delivers aggressive stock removal at 36 grit while leaving a blended finish in a single pass. At 7 inches in diameter, the disc fits standard angle grinders equipped with a quick-change hub, cutting down on disc swap time during production work. It is installed and used by fabricators, welders, and metalworkers handling demanding tasks such as weld removal, beveling, and sharp-edge work.

This flap disc is suited for heavy-duty ferrous and non-ferrous metal grinding in both fabrication shop and field environments. The alumina zirconia mineral with grinding aid outperforms standard aluminum oxide on hard metals, making it appropriate for structural steel, stainless, and similar materials. The combined grinding and blending action reduces the number of steps required to finish a weld or prepared edge, improving workflow efficiency on high-volume jobs.

Key Features

• Alumina zirconia mineral with grinding aid delivers more cutting power than aluminum oxide across all metal types
