The Zirconium Raised Hub Grinding Wheel functions as an abrasive tool that removes surface material through rotational contact with a workpiece. The raised hub profile creates clearance between the grinding surface and the mounting interface, allowing better approach angles and reducing obstruction during grinding tasks. As the wheel rotates, abrasive grains interact with the surface, cutting and removing layers to achieve the required shape and finish. The grinding wheel supports controlled material removal by maintaining consistent contact across the working face while allowing operators to guide motion along edges, flat surfaces, and contours. Attributes:• Fits 114.3 mm, 177.8 mm, and 228.6 mm (4 1/2 in, 7 in, and 9 in) grinders.• Used on electrical or air-powered right-angle or vertical shaft grinders.• Used for rough grinding applications such as grinding/smoothing weld seams and cleaning metal surfaces.Applications: The Zirconium Raised Hub Grinding Wheel is used for removing material and shaping surfaces through abrasive contact while maintaining clearance for effective grinding access.
