Measuring 8 inches in diameter by 1 inch wide with a 1-1\/4 inch arbor hole, this brush uses aluminum oxide and Cubitron abrasive grain bonded into flexible bristle segments that deliver consistent cut at 50 grit. The radial design allows the abrasive tips to contact the workpiece with minimal applied pressure, reducing operator fatigue and the risk of workpiece damage. A universal bench motor adapter is included in the package, expanding compatibility with common bench-mounted drive units.\u003c\/p\u003e\u003cp\u003eThis brush is suited for metalworking shops, HVAC fabrication work, plumbing prep, and general maintenance tasks where wire brush contamination or surface gouging is a concern. It cleans oxides, scale, rust, and light coatings from metal substrates without embedding wire fragments that can compromise welds or coatings. Typical users include pipefitters, sheet metal workers, and maintenance technicians working on steel, stainless, aluminum, and similar metals. The flange configuration supports secure mounting on standard bench motors and right-angle grinders with the appropriate arbor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide and Cubitron abrasive grain bristles deliver consistent surface action at 50 grit\u003c\/li\u003e\n\u003cli\u003eRadial bristle construction contacts surfaces at the abrasive tip, requiring minimal pressure\u003c\/li\u003e\n\u003cli\u003eSafe alternative to wire brushes — eliminates wire fragment contamination risk\u003c\/li\u003e\n\u003cli\u003e8 inches x 1 inches x 1-1\/4 inches arbor configuration fits standard bench motors\u003c\/li\u003e\n\u003cli\u003eUniversal bench motor adapter included for expanded drive unit compatibility\u003c\/li\u003e\n\u003cli\u003eWorks on a variety of coatings and base materials including steel and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with bench motors and compatible rotary drive tools accepting a 1-1\/4 inch arbor.

Power down and lock out the drive unit before mounting or removing the brush. Verify that the drive unit RPM rating does not exceed the maximum rated speed of the brush before operation. Eye protection and appropriate PPE are required during use per standard abrasive tool safety guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide and Cubitron Abrasive Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100138332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346614878514,"sku":"7100138332","price":386.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523010.jpg?v=1782085473","url":"https:\/\/voomisupply.com\/products\/3m-7100138332-radial-bristle-brush-8x1x1-25-in-50-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
