Use the Gemini® A AO Type 27 grinding and cutting wheel for all your general-purpose cutting and grinding projects. The wheel features an aluminum oxide construction that works with metals such as 400 series stainless steel, hard carbon steels and soft carbon steels. The wheel attaches to right-angle grinders for side cleaning and notching pipes and weld beads. The wheel has a long life due to its durable bond, which promotes a consistent cut rate.
