Internal Diameter Toolroom Grinding Wheels for Metals
Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces. They’re often used to make bearings.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
