At 9 inches in diameter and 0.25 inches thick, this coarse 20-grit wheel combines Zirconia Alumina and Silicon Carbide abrasive materials in a resinoid bond construction. The result is a wheel suited for heavy stock removal, weld grinding, and surface preparation on ferrous and non-ferrous metals. It is rated to a maximum of 6,600 RPM and mounts via a 7\/8-inch arbor hole. The resinoid bond and T-hardness code indicate durability under sustained grinding pressure. Licensed tradespeople and fabrication professionals are the primary installers and users of this product.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in metal fabrication shops, structural steel work, pipe fitting, and general maintenance applications where coarse grinding is required. The Type 27 depressed-center profile allows the wheel to be used at low angles for flat or surface grinding without the wheel flange interfering with the workpiece. It is compatible with standard 9-inch angle grinders equipped with a 7\/8-inch arbor. The 20-grit coarse grade makes it well suited for rapid stock removal rather than finishing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 depressed center profile for low-angle surface grinding\u003c\/li\u003e\n  \u003cli\u003eDual abrasive blend: Zirconia Alumina and Silicon Carbide for aggressive cut rate\u003c\/li\u003e\n  \u003cli\u003e20-grit coarse grade optimized for heavy stock removal and weld grinding\u003c\/li\u003e\n  \u003cli\u003eResinoid bond construction with T-hardness code for durability under load\u003c\/li\u003e\n  \u003cli\u003e6,600 RPM maximum speed rating\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders accepting a 9-inch, 7\/8-inch arbor Type 27 grinding wheel.
