Bore polishers are used for deburring, cleaning and polishing of the interior diameters of cylinders, tubes and hydraulic fittings. Flaps of abrasive cloth are stacked, inserted into a holder, and then attached to a mandrel. The flaps are designed to break down during use and reveal the next layer of abrasive. The flaps automatically adjust to the inside diameter, cleaning the entire surface with one pass. A self-centering, spring action design gives a fast and easy way to handle all inside diameter jobs. Use with BPM-4 mandrel part no. 08834154183. Extension mandrels are available for deep holes: 4” part no. 08834154185, 6” part no. 08834154186, 8” part no. 08834154187. Package of 10.
