Built with a zirconia alumina abrasive grain at 24 grit coarse grade, this wheel delivers fast stock removal on ferrous metals, welds, and hard alloys. It measures 4-1\/2 inches in diameter with a 1\/4-inch thickness and a 7\/8-inch arbor hole, rated to a maximum of 13,580 RPM. The hardness code S backing provides consistent wheel life under sustained grinding pressure in fabrication and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on standard 4-1\/2-inch angle grinders common in metal fabrication shops, welding operations, pipefitting, and structural steel work. The Type 27 depressed center profile keeps the grinding surface flat against the workpiece, making it effective for surface grinding, weld blending, and deburring on flat or slightly curved stock. It is installed and used by ironworkers, pipefitters, welders, and maintenance mechanics working with carbon steel, stainless steel, and other hard metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive for fast, aggressive stock removal on hard metals\u003c\/li\u003e\n  \u003cli\u003e24 grit coarse grade rated for weld grinding and heavy material removal\u003c\/li\u003e\n  \u003cli\u003eType 27 depressed center profile for flat surface and weld blending applications\u003c\/li\u003e\n  \u003cli\u003e13,580 maximum RPM rating compatible with standard 4-1\/2-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles via arbor connector\u003c\/li\u003e\n  \u003cli\u003eHardness code S construction for consistent performance and extended wheel life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders accepting a 4-1\/2-inch Type 27 wheel with a 7\/8-inch arbor hole, operating at or below 13,580 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and changing grinding wheels must be performed by qualified personnel with the grinder fully powered off and unplugged or locked out per applicable OSHA lockout\/tagout procedures.
