Round shank brushes are used to apply lubricant to chains and other moving surfaces.  The wisking action of the bristles evenly distributes the fluid as it reaches the contact surface.  Brushes can also help prevent dirt build up.  Bristles are available in nylon or stainless steel.  Round brushes have an aluminum holder with a mounting thread to attach to a mounting shank or directly to a supply line.
