3M 7100074821 2 Inch Non-woven Surface Conditioning Disc

Product Description

The 3M 7100074821 is a 2-inch diameter non-woven surface conditioning disc engineered for heavy-duty deburring and finishing applications. Built with an open-web, non-woven abrasive fiber construction, this disc conforms to irregular, contoured, and edged workpiece surfaces without altering the base material. The hook and loop attachment system enables fast disc changes between finishing steps, reducing downtime in multi-step workflows. Rated at 22000 RPM maximum operating speed, this disc delivers aggressive cutting action while running cool to maintain consistent surface finishes. Licensed tradespeople and fabricators working with metal, composites, or other hard materials will find this disc suited for production and maintenance environments alike.

This disc is designed for use in surface conditioning, edge deburring, and finishing operations on metal and similar substrates. It performs well in both shop and field environments where irregular surfaces, tight edges, or contoured geometry require a conformable abrasive. The open-web construction resists loading, making it effective when working on surfaces prone to clogging conventional abrasives. It is intended for use with compatible 2-inch hook and loop backup pads and right-angle or straight die grinders.

Key Features

• Non-woven abrasive construction conforms to contoured and edged surfaces without damaging base material
• Rated at 22000 RPM maximum operating speed for use with high-speed grinders and die tools
• Hook and loop attachment system allows quick disc swaps during multi-step finishing processes
• Open-web design resists loading and dissipates heat for consistent, cool-running performance
• Delivers extra cut and longer service life compared to standard SC and PD surface conditioning discs
• Aluminum oxide abrasive mineral provides aggressive cutting on metal deburring and finishing tasks

Compatibility

Designed for use with 2-inch hook and loop backup pads on compatible right-angle grinders and die grinders rated for non-woven abrasive disc use at or above 22000 RPM.

Installation Notes

Installation is performed by tradespeople and fabricators using compatible grinder equipment. Verify that the tool spindle speed does not exceed the 22000 RPM disc rating before mounting. Seat the disc firmly onto a matching hook and loop backup pad before powering on the tool. Wear appropriate PPE including eye and face protection when operating abrasive discs at speed.
