Inverted disks and coils are especially well suited for cleaning the outside surfaces of rods and shafts. 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 fibre fillings are then turned towards the centre 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.
