Our custom inverted or inside disc brushes are manufactured by taking a straight metal channel brush and forming it into a circle shape using our custom design process. The fiber fillings are then turned towards the center of the brush making this type of brush especially well suited for cleaning the outside surfaces of rods and shafts. Inverted discs also make excellent sealing devices. Carolina Brush is capable of designing and manufacturing any custom inverted disc brush to meet our customers’ application.
