This 115 mm (4.5 inch) double row cup wheel is designed for fast and efficient grinding over large areas. The double row of segments provides aggressive material removal and a long service life on concrete, masonry, and refractory surfaces. It is ideal for levelling high spots, removing tough coatings, and smoothing rough textures. With a standard 22.23 mm (7/8 inch) arbor, it fits most 115 mm and 125 mm angle grinders.
