Built with zirconia alumina abrasive at 40 grit, this coarse-grade disc delivers fast stock removal and extended disc life compared to standard aluminum oxide options. The fiberglass backing provides rigidity and support during heavy grinding applications. Rated at 30,000 RPM maximum, it accepts a Quick-Change Type R attachment for rapid disc swaps without additional hardware. Fabricators, welders, and metal finishers rely on this disc for weld blending, edge grinding, and surface conditioning.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for use on mild steel, stainless steel, and other ferrous metals in fabrication shops, maintenance facilities, and field welding environments. The Type 27 flat profile makes it well-suited for flat surface work and shallow angle grinding where consistent contact across the disc face is required. The Quick-Change Type R mount is compatible with right-angle grinders equipped with a matching mandrel, allowing fast changeovers on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40 grit zirconia alumina abrasive for coarse, high-rate material removal\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile for flat surface and low-angle grinding\u003c\/li\u003e\n  \u003cli\u003eQuick-Change Type R attachment for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing for rigidity and structural support under load\u003c\/li\u003e\n  \u003cli\u003e30,000 RPM maximum speed rating\u003c\/li\u003e\n  \u003cli\u003e3 inch diameter suits compact right-angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with right-angle grinders equipped with a Quick-Change Type R mandrel.
