3M 7100141922 Scotch-brite Sc-dh Disc 4.5 Inch Non-woven

Product Description

The 3M 7100141922 is a Scotch-Brite SC-DH Surface Conditioning Disc designed for right-angle grinder use. Built from durable, open-web non-woven fiber, this 4.5-inch disc conforms to irregular and contoured surfaces during cleaning, blending, deburring, and finishing operations. The open-web construction runs cool under load and resists material buildup, allowing extended use without frequent disc changes. A hook-and-loop attachment system secures the disc to compatible backing pads for fast changeover during multi-step finishing processes. Suitable for use on metal, composite, plastics, and other common shop materials, this disc is a standard choice for trade and industrial finishing applications.

This disc is suited to surface preparation and finishing work across a range of industries including HVAC fabrication, plumbing rough-in, electrical panel work, and general metalworking. Its conformable non-woven construction makes it effective on curved weld seams, pipe fittings, sheet metal edges, and composite enclosures. The right-angle disc format is compatible with standard 4.5-inch right-angle grinders fitted with an appropriate hook-and-loop backing pad. It handles light deburring, oxide removal, and pre-finish blending without undercutting or damaging the substrate surface.
