General Purpose Grinding Wheels for Carbon & Stainless Steel
General purpose grinding wheels optimized for cutting and light grinding of carbon steel and stainless steel are made of bonded aluminum oxide. They can also be used on other ferrous metals and alloy steels. General purpose wheels are an economical choice for low grinding volumes and smaller jobs. Aluminum oxide is a strong, sharp, and durable abrasive that withstands heat and high speeds.
Type 27 Wheel
Type 27 (sometimes called type 42) has a raised hub to allow the wheel to contact the workpiece flat or up to a 45° angle. Sometimes called depressed center or raised hub wheels, they're reinforced with fiberglass to provide extra stability when working on an edge.
