The 4.5-inch diameter wheel is constructed from a zirconia alumina and silicon carbide blend bonded with a resinoid bond, delivering aggressive stock removal on hard materials including stainless steel, non-ferrous metals, and masonry. At 24 grit coarse grade, this wheel cuts fast and is suited for weld cleanup, surface conditioning, and edge grinding. The maximum rated speed is 13,580 RPM, and the wheel measures 0.25 inches thick with a 7\/8-inch arbor hole. Licensed trades and fabrication shops use this type of wheel routinely for both shop and field work.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for angle grinder use and fits standard 4.5-inch angle grinders equipped with a 7\/8-inch arbor. The coarse 24-grit specification makes it best suited for aggressive grinding tasks such as removing welds, deburring castings, and shaping or beveling metal edges. The resinoid bond provides durability under sustained load and lateral pressure. The Type 27 depressed center profile allows the grinding face to contact the workpiece at a low angle, giving the operator improved control and visibility during grinding passes. This wheel is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 depressed center profile for low-angle contact and improved operator visibility\u003c\/li\u003e\n\u003cli\u003eZirconia alumina and silicon carbide blend abrasive for aggressive, fast cutting action\u003c\/li\u003e\n\u003cli\u003e24 grit coarse grade suited for weld removal, deburring, and surface stock removal\u003c\/li\u003e\n\u003cli\u003eResinoid bond with hardness code T for durability under sustained load\u003c\/li\u003e\n\u003cli\u003e13,580 RPM maximum rated speed compatible with standard angle grinders\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits common 4.5-inch angle grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders equipped with a 7\/8-inch arbor connection.
