GRINDING WHEEL: 305 X 50 X 38.1MM A46NV1A ALUMINUM OXIDE

* Aluminum Oxide ((A) The most common and affordable grain, best for general-purpose metalworking, mild steel, and high-tensile steels. * General purpose grinding wheel with multi bore to fit most grinders

* All white grinding wheel is made of white aluminium oxide * It is highly friable (meaning it fractures easily to expose new, sharp edges), making it ideal for the cool grinding and sharpening of heat-sensitive materials like high-speed steel (HSS), drill bits, and chisels without burning the metal(often referred to by the abrasive code WA)
