3M 7010327321 Flap Disc 577F 60 Grit 7 Inch Type 27

Product Description

The 3M 7010327321 is a Type 27 quick-change flap disc designed for high-pressure metalworking applications. Built on the 577F platform, it uses alumina zirconia mineral combined with a grinding aid to deliver faster cutting than standard aluminum oxide abrasives across steel, stainless steel, and other metal types. The disc features heavyweight polyester-backed flaps rated for demanding work including weld removal, beveling, and sharp-edge cleanup. At 7 inches in diameter and 60 grit, it handles aggressive stock removal while leaving a blended surface finish in a single pass. Each unit weighs 0.84 pounds.

This flap disc is suited for fabrication shops, structural steel work, and field welding environments where operators need to grind and blend in one step without switching discs. The quick-change attachment system reduces downtime between disc changes on compatible right-angle grinders. Typical users include ironworkers, welders, pipefitters, and metal fabricators working on heavy-duty production or maintenance tasks.

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide on all metal types
• Heavyweight polyester-backed flaps resist breakdown under high-pressure grinding conditions
• Combines grinding and surface blending into a single operation
