3M 7010326825 Alumina Zirconia Flap Disc 4 Inch 60 Grit

Product Description

The 3M 7010326825 is a coated abrasive flap disc designed for high-pressure metalworking applications. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, this 4-inch disc runs at 60 grit and delivers aggressive stock removal alongside a blended surface finish in a single pass. The alumina zirconia grain outcuts standard aluminum oxide on all common metal types, making it well suited for demanding fabrication and maintenance work. Licensed trades and fabricators working on steel, stainless, and alloys reach for this disc when weld removal, edge chamfering, or beveling is on the job list.

This flap disc is used in industrial and commercial metalworking environments, including structural fabrication shops, pipe welding, and field maintenance settings. Typical applications include weld removal, sharp-edge blending, and beveling where both material removal and surface finishing must be completed in one operation rather than two separate steps. The 4-inch diameter fits standard right-angle grinders common in those trades.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide across all metal types
• Flap construction combines grinding and blending into a single step, reducing total time on task
• Heavyweight polyester-backed flaps extend disc life under sustained high-pressure use
• Quick-change design speeds disc swaps on the grinder
• 60 grit provides aggressive material removal with a blended surface finish

Compatibility

Designed as an OEM-style replacement flap disc for use on standard 4-inch right-angle grinders in metalworking and fabrication applications.

Installation Notes

Installation is performed by metalworkers and fabricators using standard right-angle grinders. Confirm the grinder spindle size and disc mount type match before installation. Always power down and disconnect or de-energize the grinder before changing discs. Wear appropriate PPE including eye protection and gloves, and verify the grinder RPM rating meets or exceeds the disc RPM rating before operation.
