Product Details
The 3M™ paper belt 346UZ measures 36" x 75" with P180 grit and is constructed with a premium aluminum oxide mineral in an open coat design to resist loading, particularly on soft wood. It is coated on an F-weight paper backing, one of the heaviest and most rigid paper backings, offering smoother operation, higher durability, and finer finishes than cloth backed belts of the same grade. The belt features 3M Dust Management Technology, which reduces static cling of dust particles to facilitate easier evacuation when used 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, ensures smooth travel over contact wheels and platens, minimizes chatter marks, and promotes smooth, consistent finishing in either direction. The premium aluminum oxide abrasive is known for its high cut-rate, toughness, self-fracturing to expose fresh cutting edges, hardness, strength, and low heat retention, making it suitable for sanding and finishing a wide variety of substrates including ferrous alloys in woodworking and metalworking. The abrasive belt is compatible with a variety of belt sanders and comes in many widths and lengths for diverse applications. Warranty information is provided under the standard 3M terms.
