sandpaper discs or abrasive discs - sanding disc

sanding disc, also commonly referred to as sandpaper discs or abrasive discs. Function: Sanding discs are used with power tools like orbital sanders or angle grinders to smooth surfaces, remove material, or prepare surfaces for finishing (e.g., painting, varnishing). Material: They typically consist of abrasive grains (like aluminum oxide, silicon carbide, or zirconia alumina) bonded to a backing material (paper, cloth, or film). Holes: The holes in the disc are for dust extraction, allowing the sanding tool to collect debris and keep the work area cleaner. Grits: Sanding discs come in various grit sizes, indicating the coarseness of the abrasive material. Lower grit numbers signify coarser abrasives for heavy material removal, while higher grit numbers indicate finer abrasives for smoother finishes.
