Norton 66261139389 Sanding Sheet 220 Grit Aluminum Oxide

Product Description

The NORTON 66261139389 is an aluminum oxide coated sanding sheet rated at 220 grit for very fine material removal. It features a B-weight paper backing that provides a balance of flexibility and durability, making it well suited for finish sanding on flat and near-flat surfaces. The open coat density reduces loading on soft materials and resinous woods, extending usable sheet life. At 9.1 inches wide by 11.3 inches long, it fits standard 1/4-sheet and 1/3-sheet pad sanders as well as hand sanding blocks. Suitable for both dry and wet sanding applications, this sheet is part of the Series T214 line and is used across woodworking, metalworking, and surface prep trades.

This sanding sheet is designed for fine finish work including paint scuffing between coats, bare wood preparation before staining, and light metal deburring. The 220 grit designation places it in the very fine range, making it appropriate for the final stages of surface preparation rather than aggressive stock removal. Wet sanding capability adds versatility for auto body, fiberglass, and wet-finish woodworking applications where water lubrication helps control surface temperature and debris buildup.

Installation Notes

This abrasive sheet is installed by hand or loaded onto a compatible sanding pad or block. Secure the sheet firmly to the pad before operating any power sander to prevent slipping. When wet sanding, ensure any adjacent electrical components or surfaces are adequately protected from moisture. Inspect the sheet before use and replace when grit becomes visibly worn or the backing shows tears.
