Abrasive grit refers to small, hard particles or granules that are used in various industrial processes to remove material from a surface through abrasion. These particles are typically made from minerals such as silicon carbide, aluminum oxide, or diamond, and they come in different sizes and shapes.

Abrasive grit is commonly used in applications like grinding, sanding, polishing, and surface preparation. It is often embedded in abrasive tools such as grinding wheels, sandpaper, abrasive belts, or abrasive discs. When these tools are applied to a workpiece, the abrasive grit particles create friction and wear away the material, resulting in the desired surface finish or shape.

The selection of abrasive grit depends on the specific application and the material being worked on. Different grit sizes and types of abrasive particles are chosen to achieve varying levels of abrasion, ranging from coarse removal of material to fine finishing. Coarser grits are used for rough grinding or heavy material removal, while finer grits are employed for smoothing, polishing, or achieving a more precise surface.
