Dremel 2-Pack 3/4" Stainless Steel Brush is ideal for cleaning, deburring, and surface-finishing items made from stainless steel, aluminum, silver, pewter, or other white metals. It is very effective on flat surfaces and in hard-to-reach places, such as slots. The brush has stainless steel wire bristles and a 1/8" shank. Stainless steel brushes do not cause after-rust when used on corrosive-resistant materials like pewter, aluminum, and stainless steel.
