Built with an aluminum oxide abrasive and a resinoid bond, this wheel measures 9 inches in diameter and 1\/4 inch thick. It is rated to a maximum of 6,600 RPM and mounts via a standard 5\/8-11 threaded hub. Licensed tradespeople and fabricators use this wheel for grinding welds, cleaning weld beads, removing burrs, and general surface stock removal on ferrous metals. The resinoid bond provides consistent material removal and durability under sustained load.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for light industrial, commercial, and job-site metal grinding tasks. The Type 27 depressed-center profile keeps the mounting hardware reclear of the work surface, allowing flatter grinding angles. Compatible with 9-inch angle grinders equipped with a 5\/8-11 threaded spindle. Typical users include ironworkers, pipefitters, welders, millwrights, and maintenance mechanics requiring a reliable, general-purpose grinding wheel for steel and other ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 depressed-center profile for flat grinding access on metal surfaces\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable stock removal on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eResinoid bond for consistent performance under continuous load\u003c\/li\u003e\n  \u003cli\u003e6,600 RPM maximum rating for safe use on compatible 9-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded hub fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch wheel thickness suited for general-purpose grinding and weld cleanup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 9-inch angle grinders equipped with a 5\/8-11 threaded spindle and capable of operating at or below 6,600 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and wheel changes should be performed by qualified personnel with the grinder powered off and unplugged.
