3M 00751 SC-DH Hook-and-Loop Disc 7 in Coarse Brown

7-inch Coarse Surface Conditioning Disc

The 3M 00751 SC-DH disc uses a hook-and-loop backing for quick changes on compatible sanders. Its non-woven aluminum oxide construction delivers coarse-grade material removal on metal, wood or composite surfaces. The brown abrasive indicates a heavy-duty cutting action suited for surface preparation, rust removal or blending welds. This disc fits 7-inch tools with a matching hook-and-loop pad.

Coarse Grade Handles Heavy Stock Removal

The coarse aluminum oxide grain aggressively strips coatings, corrosion and mill scale without loading as quickly as coated abrasives. Non-woven fibers conform to contours and irregular shapes while maintaining consistent scratch patterns. The disc runs out when the nylon web wears through or the grain dulls beyond effective cutting. It is not designed for fine finishing, polishing or precision dimensional sanding.

Hook-and-Loop Attachment for Standard 7-Inch Sanders

The disc mounts directly to any 7-inch hook-and-loop backup pad, requiring no adhesive or tools for installation. Its non-vacuum design means dust extraction relies on the sander's own shroud or ambient collection. The open web structure resists clogging, freeing the operator from frequent disc changes during high-load work. Compatibility depends on the sander accepting a 7-inch diameter interface.
