Hook and Loop is for the sanders which require the velco back sandpaper. Adhesive back sandpaper discs are for the orbital sanders which require adhesive sandpaper. Discs usually come with adhesive, plain, or hook and loop backs. Common sizes for sanding discs (disks) are 3” 5” 6” or even 8”. Sandpaper disks are usually made to fit different types of orbital sanders.

Belts can come in many different sizes, as they can be used for portable belt sanders, or they can be used for industrial sanding machines. Sheets, usually come in 9 x 11 size however, many other sizes may be available. Sandpaper is available in sheets, belts, discs, disks, hook and loop, rolls, or adhesive. The higher the grit, the more smooth the sandpaper is. For example: the lower the grit, the more course the sandpaper is. Sandpaper grit is the courser or smoother a particular sandpaper product might be. Backing of sandpaper may be either glued to the paper or form a separate support for the moving sandpaper as in a belt sander. Flexible backing is used if it is necessary to follow irregular rounded contours of the workpiece, otherwise relatively inflexible backing should be used for regular rounded or plane surfaces. Letter nomenclature is different for cloth, with the weight of the backing being, from lightest to heaviest: J, X, Y, T and M. For paper, the letters range from A to F, with A being the lightest and F the heaviest. The weight of the backing is usually designated by a letter. Fibre or vulcanized fibre is a strong backing material consisting of many layers of impregnated paper made from rags. Cloth backing is used for sanding discs and belts, while mylar is used with extremely fine grits. In addition to paper, backing for sandpaper includes cloth (cotton, polyester, rayon), PET film, and "Fibre". old paint), or sometimes to make the surface rougher (e.g. It is used to remove small amounts of material from surfaces, either to make them smoother (painting and wood finishing), to remove a layer of material (e.g. Sandpaper is a form of paper where an abrasive material has been fixed to its surface it is part of the "coated abrasives" family of abrasive products. Sandpaper by definition is a “paper, which has abrasives material ingrained into it – part of the “coated abrasive family of abrasive products”. Abrasives are now used for wood sanding, metal sanding, glass sanding, automotive sanding and much more. As a result to the success sandpaper had on refinishing automotive materials, many different abrasive products have been introduced for all types of sanding. In 1916-sandpaper manufacturer 3M invented an abrasive, which was applied for automotive sanding and refinishing. Since then sandpaper has been made in many different ways. Glass paper (Sandpaper) was being manufactured by John Oakey's company in London by 1833, who had developed new adhesive techniques and processes that could be mass-produced. Originally Sandpaper was known as glass paper, because particles of glass was used. Sandpaper paper was made out of crushed shells, seeds, sand, and gum. patented the first process for mass manufacturing of sandpaper in the United States in 1834, sandpaper was used as far back as the 13th century in China.
