• Best For: Floor prep crews whose grinder takes a 7/8-5/8 arbor and who need a 5-inch double-row turbo cup wheel.
• Highlight: Double-row turbo design on a 5-inch (127mm) wheel with a 7/8-5/8 arbor, in the Supreme Grade MK-504SG-2 series.
• Expert Note: Fitment decides this one: this code is the 7/8-5/8 arbor version of the 5-inch MK-504SG-2; the 5/8-11 nut mount version is a separate part (158731).
