Cylindrical wire brushes, such as crimped cup brushes and twisted cup brushes, are frequently employed in surface preparation, cleaning, and deburring applications. The manner the wires are fastened to the brush cup varies, though.
Individual wire tufts are twisted into a densely packed bundle and then attached to the brush cup to create twisted cup brushes. Twisted wires are more abrasive and aggressive, which makes them perfect for heavy-duty applications including the removal of corrosion, rust, and surface coatings.
In contrast, individual wire bristles are crimped into tiny bundles and then fastened to the brush cup to create crimped cup brushes. When a less forceful brush is needed for cleaning and finishing applications, the crimping process helps to generate a softer, more flexible brushing action.
To sum up, the primary distinction between crimped cup brushes and twisted cup brushes is that the former are more flexible and less aggressive, while the latter are typically more abrasive. Depending on the application and necessary level of brushing aggression, twisted or crimped cup brushes should be used.
