GRINDING WHEEL: 150 X 25 X 31.75MM 80 GRIT A46 ALUMINUM OXIDE

* 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)

* A green grinding wheel is made of green silicon carbide (a synthetic compound of silicon and carbon) * It has ultra-high hardness and high friability, making it ideal for grinding or sharpening super-hard and non-ferrous materials like tungsten carbide, ceramics, glass, and titanium alloys * Special grinding wheel with multi bore to fit most grinders * Grit size is optional and depends on usage * Comes with plactic bush stack MP8001

* 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
