10Pcs Nylon Bore Brush 20Mm Dia 4.5" Cleaning Twisted Wire Brush

Wire cleaning brush brushes have a wide range of applications. They are twisted by twisted pairs, with many fine brush wires that are neatly arranged and stretched outward. Made of nylon, it is durable, not easy to break, easy to remove rust and dirt, and the bristles are dense and neat, and wear-resistant. Bore brush quickly enters tight holes and confined areas and is suitable for cleaning, polishing, or descaling in ports, pipes, bearings, automotive, manufacturing or machining, and other typical wire brushing applications. The 1/4" hex shank brush can be mounted on a power drill or die grinder, or on the corresponding impact driver handle for more efficient cleaning. Notice: Wire bore brush is for push-pull operations only. Mounted on a drill or corresponding driver handle, do not spin more than 600 rpm, and do not turn counter-clockwise.
