Pearl® XTREME™ PX-4000™ is a revolutionary line of diamond wheels for metal applications. It is designed to cut metal, stainless steel and a variety of ferrous metal with less odor and debris compared to conventional abrasives. The Pearl® XTREME™ PX-4000™ is engineered with a high concentration of diamonds with an extremely strong bond. The Pearl® XTREME™ PX-4000™ features fast cutting speed compared to conventional bonded abrasives and much longer life. It is extremely efficient because it reduces the need to change wheels frequently, which increases productivity dramatically. In addition, the shape of the wheel does not change overtime; therefore, the depth of cut remains the same from the first cut to the final cut.
