3M 7100020232 Scotch-brite 8 Inch Non-woven Abrasive Disc

Product Description

The 3M 7100020232 is a Scotch-Brite High Strength HS-DC non-woven abrasive disc engineered for general-purpose surface conditioning on metal. Built on a durable open-web construction, it resists loading and runs cool, which keeps the aluminum oxide abrasive cutting at a consistent rate from the first use through the end of the disc's life. At 8 inches in diameter and rated for up to 3000 RPM, it handles medium-duty deburring, cleaning, denibing, defuzzing, and satin finishing. Fabricators, metalworkers, and maintenance technicians are the primary users of this disc.

This disc is suited for surface conditioning tasks on a wide variety of metals in both shop and industrial maintenance settings. Its conformable construction allows it to follow contours while maintaining even contact, making it effective on flat stock, weld seams, and shaped components. Multiple discs can be stacked to cover larger surface areas or to build up thickness for specific applications. It is sold individually and fits standard 8-inch disc grinders and finishing machines.

Key Features

• Open-web, non-woven construction resists loading and dissipates heat for a consistent cut rate throughout disc life
• Aluminum oxide (AO) abrasive grade delivers reliable performance on ferrous and non-ferrous metals
• Medium grade abrasive suitable for deburring, denibing, defuzzing, cleaning, and satin finish work
• Wear-resistant edge promotes even wear and extends usable disc life
• Stackable design allows expanded coverage or increased surface contact area
• Rated to 3000 RPM for use on standard disc finishing equipment

Compatibility

Designed for use on standard 8-inch disc grinders and surface conditioning machines rated at 3000 RPM or higher. Confirm machine arbor size and backing pad compatibility before mounting.

Installation Notes

Installation and disc changes should be performed by qualified technicians following the equipment manufacturer's guidelines. Power down and disconnect the grinder or finishing machine before mounting or removing the disc. Verify that the machine's rated speed meets or exceeds the disc's 3000 RPM requirement and that the backing pad is in good condition before operation. Always wear appropriate PPE including eye protection and gloves when operating abrasive disc equipment.
