Tru-maxx AC411JFE400G 400 Grit Aluminum Oxide Sanding Sheet

Product Description

The TRU-MAXX AC411JFE400G is a coated abrasive sanding sheet designed for dry material removal and surface finishing applications. It uses aluminum oxide as the abrasive material, bonded in a closed-coat pattern onto a J-weight cloth backing. The J-weight cloth provides flexibility without sacrificing durability, making this sheet suited for contour sanding as well as flat surface work. At 400 grit, the sheet delivers fine finishing cuts that smooth surfaces before final coating or inspection. This product is intended for professional use in metal fabrication, woodworking, and general maintenance environments where consistent, repeatable abrasive performance is required.

This sanding sheet is used in dry grinding and finishing operations across light industrial and trade settings. The 9 inch by 11 inch format fits standard sheet sanders and can be cut to size for hand-sanding blocks. The closed-coat aluminum oxide construction removes material efficiently on hardwoods, metals, composites, and painted surfaces. It is not rated for wet or wet-dry use and should be kept dry during storage and application. Machinists, fabricators, painters, and finishing technicians are the primary users of this abrasive format.

Installation Notes

Secure the sheet firmly in the sander clamps or hook-and-loop pad before powering on the tool. Ensure the workpiece is stable and free of loose debris before beginning. Do not use this sheet with water, cutting fluids, or lubricants, as it is rated for dry use only. Inspect the sheet for tears or loading before each use and replace when abrasive performance degrades.
