It measures 7-5\/8 inches in diameter by 1 inch wide with a 1-1\/4 inch arbor hole and carries an 80-grit rating using aluminum oxide and Cubitron abrasive grain. The bristle construction allows effective material removal and surface conditioning with minimal applied pressure, making it a reliable alternative to conventional wire brushes. Each unit includes a universal bench-motor adapter flange for straightforward mounting. Licensed HVAC technicians, plumbers, pipefitters, electricians, and metal fabricators regularly use radial bristle brushes for deburring, weld cleanup, and pipe-end preparation.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for use on metal, painted surfaces, welds, and oxidized or coated substrates encountered in residential and commercial trade work. The radial bristle design conforms to irregular surface profiles and contours, allowing consistent abrasive contact without gouging or undercutting base material. Typical applications include removing mill scale, corrosion, light coatings, and surface contaminants from pipe, conduit, sheet metal, and structural components. The included bench-motor adapter makes it compatible with standard bench grinders and similar rotary equipment found in most trade shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide and Cubitron abrasive grain for consistent cut and long service life\u003c\/li\u003e\n  \u003cli\u003e80-grit rating suited for moderate material removal and surface conditioning\u003c\/li\u003e\n  \u003cli\u003eRadial bristle design cleans and abrades with minimal applied pressure\u003c\/li\u003e\n  \u003cli\u003eSafe alternative to wire brushes, reducing risk of wire fragment embedment\u003c\/li\u003e\n  \u003cli\u003eIncludes universal bench-motor adapter flange for easy mounting\u003c\/li\u003e\n  \u003cli\u003eWorks on a variety of coatings, metals, and surface conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard bench grinders and rotary equipment accepting a 1-1\/4 inch arbor.
