Granite Cutting The process used for cutting hard stone, and especially granite, has been revolutionized by the introduction of steel abrasives. This has helped the stone industry worldwide to soar from a craft to a full industry. Today, granite blocks from around the world (India, Brazil, Italy, etc.) are cut into thin slabs on huge multi-blade gangsaws.  The steel grit is actually the cutting material as it is ground between the blades and the stone. The PanAbrasive cast steel grit has been accepted in North America and around the world as the best product for granite cutting. Copyright © 2000 PanAbrasive inc. All rights reserved. Questions?
