3M 7100045908 Scotch-brite Abrasive Disc 8 in Medium Ao

Product Description

The 3M 7100045908 is a Scotch-Brite High Strength non-woven abrasive disc designed for general-purpose surface finishing tasks in metal fabrication and manufacturing environments. Built on a durable open-web construction, the disc resists loading and runs cool, which keeps the aluminum oxide abrasive cutting consistently throughout the disc's usable life. At 8 inches in diameter with a 1/2-inch arbor, this medium-grade disc handles deburring, cleaning, denibing, defuzzing, and satin finish work on a wide variety of metal surfaces. Fabricators, machinists, and metalworking technicians are the primary users.

This disc is suited for use in production and maintenance environments where consistent surface finish results are required on metal workpieces. The conformable, non-woven material follows contours without gouging, making it practical for both flat and slightly irregular surfaces. Multiple discs can be stacked on the arbor to expand coverage or increase aggressiveness, which extends its utility across a broader range of applications. The wear-resistant edge contributes to a longer service life compared to standard woven abrasive discs.

Key Features

• Open-web non-woven construction resists loading and runs cool for a consistent cut rate

Compatibility

Designed for use with right-angle grinders and disc sanders fitted with a 1/2-inch arbor accepting 8-inch diameter non-woven abrasive discs.

Installation Notes

Installation is performed by qualified metalworking or maintenance personnel. Ensure the grinder or sander is fully powered down and disconnected from the power source before mounting or removing the disc. Confirm that the arbor size and RPM rating of the tool are compatible with this disc before operation. Follow all applicable ANSI B7 safety standards for abrasive wheel mounting and use.
