4 in. JX Dry Diamond Polishing Pads are designed to polish marble, granite, travertine, concrete and other types of stones. They are suitable for dry use on the job sites or out door where water is not desired. They are aggressive compared to resin bonded wet and dry pads. Compare to wet pads, they are typically thinner and not as long-lasting. Use of dust shroud and vacuum to minimize dust while polishing is strongly recommended. A 4 in. semi-rigid back holder is included in this set to use with these diamond polishing pads. The semi-rigid back holder is Velcro faced and made with rubber and brass thread body. Semi-rigid is suitable for polishing both edges and surface. Brass female thread has 5/8-11 thread to fit on most polishers and variable speed grinders.
