Product Details
3M™ paper belt 346UZ measures 37" x 75" and is constructed with a premium aluminum oxide mineral combined with an open coat construction for loading resistance, coated on an F-weight paper backing. The F-weight paper backing is one of the heaviest and most rigid available, providing smooth operation, durability, and finer finishes compared to cloth-backed belts of the same grit. The open coat structure resists loading better than closed coat belts, particularly on soft wood, and features 3M Dust Management Technology that reduces static cling in dust particles for easier evacuation with an efficient dust collection system. The belt ends are joined using a sine wave splice that enhances belt strength, resists hinging and splice fatigue, travels smoothly over contact wheels and platens, minimizes chatter marks, and promotes smooth operation in either direction for consistent finishing results. The aluminum oxide abrasive is known for its high cut-rate, toughness, long life, self-fracturing properties that expose fresh cutting edges, and low heat retention, making it suitable for sanding and finishing applications on a wide variety of substrates including wood, metal, and ferrous alloys. The kit includes the abrasive belts ready for use with various belt sanders across multiple applications. The product meets standard industrial quality requirements, though specific certifications are not listed in the provided information. Warranty terms apply as per 3M's policies.
