It features an 80-grit zirconia alumina abrasive coating rated for medium-grade material removal. The fiberglass backing provides rigidity and heat resistance during aggressive stock removal. A Quick-Change Type R attachment makes disc swaps fast without additional hardware. Rated to 30,000 RPM, this disc suits high-speed angle grinders and die grinders used in fabrication, welding cleanup, and surface prep. It is installed and used by metal fabricators, pipefitters, ironworkers, and maintenance technicians who need consistent cut rate and disc longevity.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for grinding, deburring, and blending welds on carbon steel, stainless steel, and similar ferrous metals. The Type 27 flat profile is the standard choice for flat surface work and inside radius grinding. The 3-inch diameter targets tight access areas and smaller angle grinders or die grinders common in mechanical and fabrication shops. The Quick-Change Type R mount allows tool-free disc changes on compatible mandrels, reducing downtime during repetitive surface prep tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-grit zirconia alumina abrasive for medium-grade stock removal and blending\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile optimized for flat surface grinding and weld blending\u003c\/li\u003e\n\u003cli\u003eQuick-Change Type R attachment for tool-free disc changes on compatible mandrels\u003c\/li\u003e\n\u003cli\u003eFiberglass backing delivers rigidity and thermal stability under load\u003c\/li\u003e\n\u003cli\u003e30,000 RPM maximum speed rating compatible with high-speed die grinders\u003c\/li\u003e\n\u003cli\u003eCompact 3-inch diameter suits confined work areas and smaller grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Quick-Change Type R mandrels on angle grinders and die grinders that accept 3-inch flap discs.
