3M 7000028428 Scotch-brite Sc-dh Disc 4 Inch Non-woven

Product Description

The 3M 7000028428 is a Scotch-Brite SC-DH Surface Conditioning Disc built for cleaning, blending, deburring, and finishing across a range of materials. Constructed from durable non-woven fiber, the disc conforms to irregular or contoured surfaces without undercutting or damaging the base material. At 4 inches in diameter, it mounts via a hook and loop attachment system for fast changeover during multi-step finishing operations. The open web construction runs cool and resists loading, extending working life during sustained use. Suitable for metal, composite, plastics, and similar substrates.

This disc is designed for use with right-angle grinders or disc tools that accept 4-inch hook and loop abrasive discs. It fits common surface preparation workflows in fabrication, welding cleanup, and finishing environments. The conformable non-woven construction makes it well suited for contoured workpieces where rigid abrasives would leave uneven results. Technicians and fabricators use it as a first-step surface conditioning tool before progressing to finer finishing stages.
