Granite Cutting Grit is manufactured from cast steel shots which have been crushed to granular grit form and subsequently tempered for granite cutting application. It has uniform hardness, density and microstructure; and is durable. The Granite Cutting Grit is available in all size ranges conforming to SAE & JIS specifications. Standard grade materials are formulated to meet the general requirements. We are able to customise special cutting grades accouding to your requirements of hardness and/or size specifications and/or mixed with shots, upon request.
