A brass wire cup is a type of wire brush that is used for cleaning, polishing, and deburring metal surfaces. The wire cup is made up of multiple strands of brass wire that are twisted together and attached to a central arbor or shaft.
Brass wire cups are available in various sizes and shapes, with different diameters and bristle lengths to suit different applications. They are commonly used on electric or pneumatic angle grinders, which allow for quick and easy removal of rust, paint, and other surface contaminants from metal workpieces.
Brass wire cups are typically less aggressive than steel wire cups, making them suitable for use on softer metals such as aluminum and copper, as well as for more delicate finishing work. They are also less likely to create sparks or generate heat, making them a safer choice for use in certain applications.
However, it's important to note that brass wire cups should not be used on stainless steel or other corrosion-resistant alloys, as the brass can cause contamination and damage to the surface of the metal. In these cases, stainless steel or nylon wire cups should be used instead.
