• Best For: Floor prep crews whose grinder takes a 7/8-5/8 arbor and who want a 7-inch single-row turbo cup wheel.
• Highlight: Single-row turbo segments on a 7-inch (178mm) wheel with a 7/8-5/8 arbor, in the Supreme Grade MK-504CG-1 series.
• Expert Note: Check the mount before ordering: this is the 7/8-5/8 arbor version of the 7-inch MK-504CG-1; the 5/8-11 nut version is a separate part (158733).
