Internal brushes, also known as "side action" brushes, are designed for use on portable tools and drill presses. They provide hard-working brush action for fast, thorough cleaning and finishing in such hard-to-reach places as small diameter holes, internally threaded surfaces, and many otherwise inaccessible areas. Fill materials include steel, stainless steel, brass, nylon, and abrasive nylon filament.
