3M 7010329404 Hook Loop Abrasive Disc 3 in Aluminum Oxide

Product Description

The 3M 7010329404 is a 3-inch hook and loop abrasive disc designed for surface preparation, finishing, and blending on metal, wood, and composite materials. Built with aluminum oxide abrasive on a flexible, non-woven backing, this disc delivers consistent medium-grade cutting action while conforming to contoured and irregular surfaces. The hook and loop attachment system allows fast disc changes without tools, making it a practical choice for production environments and service work alike. At a maximum operating speed of 18,000 RPM, it is suited for use with standard random orbital and right-angle die grinders equipped with a compatible hook and loop pad.

This disc is commonly used in metal fabrication, automotive bodywork, HVAC sheet metal finishing, plumbing rough-in cleanup, and general maintenance applications. The flexible non-woven construction allows it to conform to curved surfaces and weld areas without gouging. The maroon disc is part of the 3M SE-DH series and meets AMED specification standards. It is sold individually and is appropriate for professional tradespeople who require a reliable, repeatable abrasive solution for light material removal and surface blending tasks.

Installation Notes

Ensure the tool is powered off and disconnected from its air or electrical supply before attaching or removing the disc. Press the disc firmly onto the hook and loop backing pad to ensure full contact before operating. Do not exceed the rated maximum speed of 18,000 RPM. Inspect the disc and backing pad for wear or damage before each use and replace if the abrasive surface is loaded or the backing shows separation.
