• Best For: Floor prep crews whose grinder takes a 5/8-11 nut mount and who need a 5-inch single-row cup wheel.
• Highlight: Single-row turbo design on a 5-inch (127mm) wheel with a 5/8-11 nut mount, in the Supreme Grade MK-504CG-1 series.
• Expert Note: Fitment decides this one: this code is the 5/8-11 nut mount version of the 5-inch MK-504CG-1; the 7/8-5/8 arbor version is a separate part (158730).
