Product Details
The 3M™ paper belt 346UZ measures 54" x 103" with a P180 grit aluminum oxide abrasive. It is constructed with a premium aluminum oxide mineral and features an open coat construction designed for loading resistance, coated on an F-weight paper backing that provides smooth operation and durability. The F-weight paper backing is one of the heaviest and most rigid available, achieving finer finishes than cloth-backed belts of the same grade. The open coat abrasive resists loading better than closed coat belts, especially on soft wood, and incorporates 3M dust management technology to reduce static cling, facilitating easier dust evacuation when used with an efficient dust collection system. 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 a tough, durable mineral that self-fractures to expose fresh cutting edges, offering a high cut-rate, hardness, strength, and low heat retention; it is suitable for sanding and finishing applications on a wide variety of substrates including woodworking materials and ferrous metal alloys. The belt is compatible with various belt sanders and used for finishing wood and metal surfaces. Warranty terms apply as specified by 3M for their abrasive products.
