3M 140N Garnet Abrasive Sheet

Our 3M™ paper sheet 140N is a general-purpose, open-coat garnet abrasive sanding paper for sanding wood by hand. The durable D-weight backing makes this sheet ideal for heavy-duty hand sanding in earlier stages of woodworking operations. Our 3M™ paper sheet 140N features a more rugged paper backing and sharp garnet mineral. The D-weight backing is one of the heavier backings among paper backed sheets. It's tough enough to remove surface defects left by machine sanding before finishing. Abrasives cut better and last longer when dust isn't clogging the cutting surface of the abrasives. Open-coat construction means the abrasive grains are less densely spaced on the backing, allowing sawdust to be evacuated keeping cutting mineral free. This allows the sheet to continue cutting even when sanding soft woods and materials that would, otherwise, clog the grain and hinder sanding ability.
