3M 7100192471 Scotch-brite Non-woven Disc 27 in Medium

Product Description

The 3M 7100192471 is a Scotch-Brite High Strength non-woven abrasive disc designed for general-purpose surface preparation in metalworking and fabrication environments. Built on a durable open-web construction, it resists loading and runs cool, which keeps the aluminum oxide abrasive cutting at a consistent rate throughout the disc's service life. At 27 inches in diameter and rated for 550 RPM, this medium-grade disc handles deburring, denibing, defuzzing, cleaning, and satin finishing on a wide range of metal surfaces. It is installed by machinists, fabricators, and finishing technicians on large disc grinders and surface finishing machines.

This disc is suited for heavy-duty metal surface preparation in both production and job-shop settings. The conformable construction follows surface contours, and the wear-resistant edge supports consistent finishes across the full disc life. Discs can be stacked to increase working thickness or to cover larger surface areas, making this format practical for high-volume finishing runs on flat or moderately contoured metal workpieces.

Key Features

• Open-web, non-woven construction resists loading and dissipates heat during use
• Aluminum oxide abrasive grade delivers consistent cut rate from start to finish
• Medium grit designation suitable for deburring, denibing, defuzzing, and satin finishing
• Conformable disc body with wear-resistant edge for uniform surface contact
• Stackable design allows increased thickness or expanded surface coverage
• Rated to 550 RPM for use on large disc finishing equipment

Compatibility

Designed for use on large disc grinders and surface finishing machines that accept 27-inch non-woven abrasive discs rated at 550 RPM. Verify machine arbor size, RPM rating, and disc retention hardware before installation.

Installation Notes

Installation of large-diameter abrasive discs should be performed by qualified metalworking or fabrication personnel following the machine manufacturer's mounting instructions. Confirm the grinder is de-energized and locked out before mounting or removing the disc. Do not exceed the 550 RPM maximum speed rating. Inspect the disc for damage before each use and replace immediately if tears, gouges, or separation are observed.
