Built on an open-web RC substrate with aluminum oxide mineral, the disc delivers consistent cut rate from first contact through extended use. The RC material breaks down gradually under medium pressure to expose fresh abrasive fibers, and the open web resists loading from paint, corrosion, and soft-metal debris. Rated for use at up to 18000 RPM, the 3-inch disc accepts standard quick-change fastening systems for fast swaps without stopping the grinder.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for flatwork, composite panels, and softer metals such as aluminum. Typical applications include blending welds, removing coatings, light deburring, and surface prep on flat stock. The open-web construction responds to minor surface irregularities and reduces the risk of gouging. Available in multiple grades: dark brown extra coarse, brown coarse, maroon medium, and blue very fine, allowing the same tool setup to handle a range of prep stages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide on RC material provides consistent initial and extended cut rate\u003c\/li\u003e\n  \u003cli\u003eOpen-web substrate flexes to surface irregularities and resists gouging\u003c\/li\u003e\n  \u003cli\u003eLoad-resistant construction reduces clogging on composites and soft metals\u003c\/li\u003e\n  \u003cli\u003eQuick-change attachment system speeds disc swaps and reduces downtime\u003c\/li\u003e\n  \u003cli\u003eRated at 18000 RPM for use with standard air and electric angle grinders\u003c\/li\u003e\n  \u003cli\u003eAvailable in extra coarse, coarse, medium, and very fine grades\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard quick-change disc grinder systems accepting 3-inch surface conditioning discs.
