It measures 8 inches in diameter by 1 inch in width with a 1.25-inch arbor hole and is rated at 120 grit. The brush uses aluminum oxide and Cubitron abrasive grain bonded into flexible bristle segments that flex under contact, delivering consistent abrasion with minimal applied pressure. The package includes a universal bench motor adapter, making setup straightforward on standard bench grinders and polishing motors. Trade professionals use this brush as a direct replacement for wire brushes where reduced surface aggression is required.\u003c\/p\u003e\n\u003cp\u003eThis radial bristle brush suits light to medium surface preparation tasks including weld seam blending, rust and scale removal, paint stripping, and general deburring on ferrous and non-ferrous metals. The flexible bristle design conforms to contoured and irregular surfaces, making it practical for pipe ends, valve bodies, fittings, and fabricated assemblies. It is appropriate for use in HVAC sheet metal fabrication, plumbing, and general mechanical service environments where a safe alternative to rigid wire brushes is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120 grit aluminum oxide and Cubitron abrasive grain for consistent material removal\u003c\/li\u003e\n  \u003cli\u003eFlexible bristle construction conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eCleans and preps with minimal applied pressure, reducing surface damage risk\u003c\/li\u003e\n  \u003cli\u003eSuitable replacement for wire brushes in surface cleaning and coating removal applications\u003c\/li\u003e\n  \u003cli\u003eIncludes universal bench motor adapter for bench grinder compatibility\u003c\/li\u003e\n  \u003cli\u003e1.25-inch arbor hole fits standard bench motor spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard bench grinders and polishing motors accepting a 1.25-inch arbor.
