This Is Dremel"s 1/8" Stainless Steel Brush Accessory Bit. FEATURES: An end-shaped brush with stainless steel wire bristles. Stainless steel brushes do not cause "after-rust" when used on corrosive-resistant materials like pewter, aluminum, and stainless steel. Ideal for cleaning, deburring, and surface-finishing items made from stainless steel, aluminum, silver, pewter or other white metals. Very effective in hard-to-reach places, such as slots. INCLUDES: One Stainless Steel Brush Bit REQUIRES: Rotary Tool Eye Protection SPECS: Brush Diameter: 1/8" (3.2mm) Shank Diameter: 1/8" (3.2mm) Max. Operating Speed: 15,000 RPM COMMENTS: Do not use stainless steel brushes in areas where carbon steel particles may come in contact with the brush (such as steel work- benches). This prevents rust and contamination. Always store stainless steel brushes apart from carbon steel brushes. kr10/2/01 ir/kh
