Harder and more brittle materials like tool steel, cemented carbide, and glass are best suited for a fine-grit abrasive. Grades. A bench grinder wheel's grade tells the holding power that its bond has, which contains abrasive grains inside the wheel. ... Many people even have these in their house for their grinding wheel needs. #2: Grinding ...
Similarly, the harder the abrasive, the better the material removal ability of the grinding wheel. Based on the abrasive material, there are four types of grinding wheels: Aluminium Oxide Abrasives. Aluminium oxide is the most commonly used abrasive on grinding wheels and is best suited for grinding ferrous metals and steel workpieces.
Grinding Wheels. Grinding wheels have two major components: the abrasive grains and the bond. The relative percentages of grain and bond, and their spacing on the wheel, determine the wheel's structure. Different types of grains work better on different projects, as do different types and "grades" (i.e. strengths) of bond.
tool steel is hard to grind, the right wheel for this would be a silicon carbide grinding wheel. plenty of coolant as it will crack, aluminum oxide wheel will require dressing every part and will glaze which causes cracks, due to heat build up. check with …
