POLISTAR pads are flexible tools for grinding on internal surfaces of bores or pipes. These coated abrasive, star-shaped pads offer high flexibility, and are perfect for grinding internal surfaces of small-diameter bores or pipes. Their small diameters makes these tools particularly suitable for use on 1/4“to 2“ diameter ID’s.
POLISTAR pads can be stacked in several layers. To benefit from a maximum abrasive surface area, ensure that the lobes of the individual star pads are aligned offset.
