The wheel measures 4-1\/2 inches in diameter and 1\/8 inch thick, with a 7\/8-inch arbor hole for standard angle grinder compatibility. It is constructed from aluminum oxide abrasive bonded with a resinoid bond, rated at 80 grit for medium-grade stock removal. Maximum rated speed is 13,300 RPM. This wheel is used by fabricators, welders, pipefitters, and general trade contractors for grinding welds, deburring steel, and surface preparation work.\u003c\/p\u003e\n\u003cp\u003eThe FA4580 fits standard 4-1\/2-inch angle grinders commonly used in fabrication shops, job-site metalwork, and maintenance applications. The Type 27 depressed-center profile keeps the wheel hub recessed, allowing flat grinding passes close to workpiece surfaces without obstruction. The 80-grit aluminum oxide construction makes it well suited for carbon steel, stainless steel, and cast iron grinding where moderate material removal and surface blending are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 depressed center profile for flat-surface grinding passes\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch diameter with 1\/8 inch wheel thickness\u003c\/li\u003e\n  \u003cli\u003e80 grit aluminum oxide abrasive for medium-grade material removal\u003c\/li\u003e\n  \u003cli\u003eResinoid bond for durable abrasive retention under load\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum speed rating\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits standard angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-1\/2 inch angle grinders equipped with a 7\/8-inch arbor.
