About Angle Grinding Wheels (Type 27, 28, & 29)

These depressed-center grinding wheels, also known as raised hub wheels, attach to your angle grinder for heavy stock removal, blending, and notching using the face of the wheel. They are ideal for on-site grinding and when the workpiece is too big for grinding on a bench or pedestal grinder.
