Abrasive grit encapsulated into the extruded nylon filament allows an abrasive nylon brush to perform deburring, edge blending, and surface finishing. Abrasive brushes in power brush or wide face cylinder brush format deliver the flexibility and conformability of a brush, while also imparting the benefits of an abrasive: selection of grit sizes to control finish, and functionality for deburring, cleaning, surface finishing, and edge blending. Abrasive Nylon is suitable for use on a broad range of materials.
