3M 7010326511 Psa Abrasive Disc 16 Inch 40 Grit

Product Description

The 3M 7010326511 is a pressure-sensitive adhesive (PSA) abrasive disc built for aggressive material removal in coarse grinding and surface preparation applications. The disc measures 16 inches in diameter and carries a 40-grit aluminum oxide abrasive, placing it in the coarse grade range suited for rapid stock removal, weld blending, and heavy surface conditioning. An X-weight cloth backing provides the stiffness and tear resistance needed for demanding bench-top and orbital sanding work. The maroon disc mounts quickly via PSA backing, eliminating the need for mechanical fasteners during disc changes. Weighing 0.62 pounds, it is a single-disc unit intended for professional use.

This disc is designed for use on bench-top motors and random orbital sanders where a large-diameter, coarse-grit disc is required. Typical applications include metal fabrication shops, woodworking operations, and industrial surface prep tasks where fast cutting action and consistent abrasive performance are priorities. The flexible cloth construction allows the disc to conform slightly to workpiece contours, making it effective on both flat stock and mildly contoured surfaces. The 3M 348D series designation identifies it as part of a family of industrial-grade coated abrasive products.

Compatibility

Designed for use with bench-top motors and random orbital sanders that accept 16-inch PSA-mount abrasive discs.

Installation Notes

Installation is performed by trade professionals or experienced operators familiar with abrasive sanding equipment. Power down and de-energize the sander or bench motor completely before removing the spent disc and applying the new one. Ensure the platen surface is clean and free of adhesive residue before pressing the PSA disc firmly into full contact. Do not exceed the machine's rated disc diameter or RPM specification when selecting replacement discs.
