Running on a Type R Quick-Change connector, this brush mounts and dismounts without tools, reducing downtime between abrasive changes. The ceramic abrasive grain is rated Very Coarse at 36 grit, making it well-suited for stripping rust, scale, paint, and oxidation from steel and other hard metals. Round filaments in a straight disc configuration deliver consistent, repeatable scratch patterns. Each package contains 3 brushes. Installation is handled by licensed machinists, fabricators, and trade professionals using compatible Type R right-angle die grinders or drills.\u003c\/p\u003e\n\u003cp\u003eThis disc brush is designed for handheld power tool applications including angle grinders and die grinders equipped with a Type R Quick-Change arbor system. Typical use cases include weld seam blending, deburring, rust and paint removal on structural steel, pipe, and sheet metal. The 36 grit ceramic abrasive is aggressive enough for initial surface conditioning passes before finishing steps. The 0.37-inch arbor hole and 3\/4-inch trim length are sized for standard Type R mandrel compatibility. Sold in a package of 3 brushes per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive stock removal and long service life on hard metals\u003c\/li\u003e\n  \u003cli\u003e36 grit Very Coarse grade suited for rust, scale, and paint stripping\u003c\/li\u003e\n  \u003cli\u003eType R Quick-Change connector for fast, tool-free disc swaps\u003c\/li\u003e\n  \u003cli\u003e3-inch outside diameter fits standard Type R right-angle grinder mandrels\u003c\/li\u003e\n  \u003cli\u003eRated to 18,000 RPM for use with high-speed power tools\u003c\/li\u003e\n  \u003cli\u003eRound filament, straight disc configuration delivers uniform scratch pattern\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with power tools equipped with a Type R Quick-Change mandrel system.
