Product Details
The 3M™ paper belt 346UZ measures 52 inches by 103 inches and features a P120 grit premium aluminum oxide mineral, known for its high cut-rate, durability, hardness, strength, and low heat retention, making it suitable for sanding and finishing on a wide range of substrates including wood, metal, and ferrous alloys. The belt is constructed with an open coat design on an F-weight paper backing, which is one of the heaviest and most rigid paper backings, providing loading resistance and achieving finer finishes than cloth-backed belts of the same grit. The abrasive side's open coat structure resists loading particularly on soft wood, while the 3M Dust Management Technology reduces static cling in dust particles, facilitating easier evacuation with an efficient dust collection system. The belt ends are joined with a sine wave splice that enhances belt strength, resists hinging and splice fatigue, travels smoothly over contact wheels and platens, minimizes chatter marks, and ensures smooth operation in both directions for consistent finishing results. This kit is compliant with industrial use standards and backed by 3M’s warranty terms.
