About Norton 3X High Performance Portable Sanding
The Norton 3X sanding belt for portable belt sanders is suitable for general-purpose grinding of wood, metal, plastic, and fiberglass. The bi-directional belt splice allows the belt to run in both directions to simplify mounting and maximize sanding life. The zirconia alumina grit is self-sharpening and more durable than aluminum oxide. It is recommended for heavy material removal or coarse finishes. The belt has an open coat, which resists clogging and promotes flexibility. Open coat abrasives produce a rougher finish when abrading difficult-to-sand materials because the abrasive grains are spaced farther apart than they are on a closed coat product. Cloth backing withstands repeated flexing for maximum contouring to odd shapes and corners, and is more durable and tear-resistant than paper backing. Recommended Grit Sizes 120 grit (fine) For surface preparation before applying a stain, primer, or sealer 80 grit (medium) For light sanding of surfaces or moderate removal of rust or coatings 50 grit (coarse) For heavy sanding and stripping 36 grit (extra coarse) For heavy material removal and abrasive planingCoated abrasives have individual abrasive grains spaced at a predetermined distance from one another. They are used for a variety of applications — from shaping a part to fine finishing, depending on grit size. Low grit numbers such as 40 are coarse and are used for removing excess material and shaping a part. High grit numbers such as 400 are rated as fine and help create a smooth surface finish. Closed coat abrasives are 100 percent covered with abrasive grains, which extends the abrasive's life, maximizes material removal, and achieves finer finishes on metals and hard materials than an open coat. Closed coats are o
