A Wire Cup Brush Crimped Plain 100mm x M14 Bulk is a type of abrasive tool used for cleaning, surface preparation, or rust removal, typically in metalworking or industrial applications. The 100mm refers to the diameter of the brush, providing a wide surface area for cleaning. The M14 is the thread size, which allows the brush to be attached to a grinder or other power tools with an M14 spindle. The crimped wire design means the wires are bent, offering flexibility for more aggressive cleaning without damaging the surface. The plain version indicates that the brush does not have additional coatings or treatments, and bulk refers to it being sold in larger quantities, ideal for high-volume use.
