Norton Abrasives air cooled medium density backup pads are designed for medium duty grinding applications. They feature rubber construction with slotted hub design to draw cool air behind the discs, ensuring durability & prevention from vibrations. These pads have curved ribs on the rubber face to force heat away from the grinding zone for minimising disc loading and increasing grinding life. The threaded, female arbor hole mounting attachments fit small size holes and provide a maximum speed of 12000 rpm. Choose from a wide range of these backup pads, available in diameters of 4 and 4.5 inches.
