Norton Belt Cleaning Stick 6" Length x 1-3/8" Width x 1-3/8" Height (Pack of 1) The Norton Belt Cleaning Stick cleans wood, plastic, and other nonmetallic materials from sanding belts for improved cut rate and extended belt life. Regular use of the belt cleaning stick can prolong the life of the sanding belt up to 10 times. Apply the cleaning stick to the face of the belt while the sander is running to remove unwanted material. Made from 100% natural rubber, the stick measures 1-3/8 x 1-3/8 x 6 inches (H x W x L). Coated 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 only recommended for use with non-clogging materials. For open coat abrasives, 50 to 75 percent of the surface is evenly covered, which provides a rougher finish because the abrasive grains are spaced farther apart than on a fully coated product. The gritless spaces promote flexibility and resist clogging when abrading difficult-to-sand materials. The flexibility or rigidity of the abrasive product is also affected by the choice of backing material (either paper, cloth, or fiber). Paper backing, the most flexible backing option, contours to the workpiece and delivers a more consistent finish than fiber or cloth backings. Paper backings are categorized by weight from lightest to heaviest (A- to F-weight respectively). Cloth backings are slightly more rigid, durable, and tear resistant than paper backing, but can still withstand repeated flexing. Cloth backing is categorized by weight from lightest to heaviest (J-, X-, Y-, and H-weight respectively). Fiber backing is the strongest and most rigid backing option, and is recommended for aggressive material removal. Norton Abrasives manufactures sanding, grinding, and polishing abrasives.
