Sandpaper, also known as glasspaper or as coated abrasive, is a type of material that consists of sheets of paper or cloth with an abrasive substance glued to one face. [1] In the modern manufacture of these products, sand and glass have been replaced by other abrasives such as aluminium oxide or silicon carbide.
ISO 6344 is an international standard covering the materials sizes and tests regarding sandpaper and other similar coated abrasives. It has three parts: ISO 6344-1:1998: Grain size distribution test; ISO 6344-2:1998: Determination of grain size distribution of macrogrits P12 to P220
the statement "Grit refers to the average particle diameter and is marked on the reverse of the sheet" is false because the quoted number is typically inversely related to the particle size, and refers not to the particle size per se but to the mesh number of the sieve(s) used to separate the particle grades. Typically 100 grit means it was a ...

Sandpaper is a very common coated abrasive. Coated abrasives are most commonly the same minerals as are used for bonded abrasives. A bonding agent (often some sort of adhesive or resin) is applied to the backing to provide a flat surface to which the grit is then subsequently adhered.
The term is based on the word "whet", which means to sharpen a blade, [3] [4] not on the word "wet". The verb nowadays to describe the process of using a sharpening stone for a knife is simply to sharpen, but the older term to whet is still sometimes used, though so rare in this sense that it is no longer mentioned in, for example, the Oxford Living Dictionaries.
CFG has grinding depth up to 6 mm (0.236 inches) and workpiece speed is low. Surfaces with a softer-grade resin bond are used to keep workpiece temperature low and an improved surface finish up to 1.6 μm Rmax. CFG can take 117 s to remove 1 in 3 (16 cm 3) of material. Precision grinding would take more than 200 s to do the same.
