Resinoid cut-off wheels are made of a mixture of resin and abrasive powder and are suitable for cutting most materials. The nature of the abrasive and the hardness of the resin used are fundamental elements to ensure a perfect cut. The harder the material is, the softer the cut-off wheel must be. Cut-off wheels made of abrasive Al2O3 (alumina) are intended for cutting ferrous materials. Cut-off wheels made of abrasive Sic (silicon carbide) are intended for cutting non-ferrous materials.
Metallic cut off-wheels and CBN cutting discs only cut hard materials. There are two types of abrasives: diamond and boron nitride (CBN). Resin bonds give better surface conditions than metal bonds. Metal bonds have a longer life than resin bonds.
