3M 7010325647 Aluminum Oxide Sheet 346U 80 Grit

Product Description

The 3M 7010325647 is an aluminum oxide abrasive sheet designed for hand sanding and finishing applications in trade and light industrial environments. Built on a D-weight paper backing, this open-coat sheet uses aluminum oxide mineral to cut efficiently across a range of materials including wood, paint, and metal surfaces. At 80 grit, it falls in the coarse-to-medium range, making it well suited for material removal, surface prep, and smoothing prior to finer finishing passes. The open-coat construction reduces loading and helps the sheet perform longer between changes, particularly on softer or resinous materials.

This sheet measures 3.67 inches x 9 inches, a standard hand-sheet size compatible with hand-sanding blocks and similar manual sanding tools. It is used across finishing trades, carpentry, auto body prep, and general surface preparation tasks. The sheet is sold individually and is intended for applications where a consistent, controllable cut is needed without the complexity of a power sander. Minimum order quantities apply per supplier specification.
