Rows of nonwoven abrasive material are arranged in a radial brush configuration, giving the tool conformability that adapts to contoured surfaces and irregular geometry. At 4.5 inches in diameter with a 4-inch face width and a 5\/8-11 arbor thread, it mounts directly to compatible angle grinders and inline sanders. The 5A Medium grade positions this brush for general-purpose blending, deburring, and pre-finish work where a controlled, uniform scratch pattern is required. Weighing 0.89 pounds, it is a practical shop tool for sheet metal fabrication, welding cleanup, and structural finishing applications.\u003c\/p\u003e\n\u003cp\u003eThis flap brush is suited for metal finishing tasks in fabrication shops, manufacturing environments, and field welding operations. It performs on ferrous and nonferrous metals including steel, aluminum, and stainless. The nonwoven construction delivers a consistent cut rate throughout the life of the brush, avoiding the aggressive stock removal associated with bonded abrasive wheels. It is intended for use with the 3M line of 1HP inline sanders and compatible 5\/8-11 threaded angle grinders. A four-way keyway attachment design allows fast tool changeover without special hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRadial nonwoven construction provides conformability on curved and irregular metal surfaces\u003c\/li\u003e\n  \u003cli\u003e5A Medium abrasive grade for blending, deburring, and pre-finish scratch pattern work\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 arbor thread fits standard angle grinders and 3M 1HP inline sanders\u003c\/li\u003e\n  \u003cli\u003eFour-way keyway attachment enables quick, tool-free changeover\u003c\/li\u003e\n  \u003cli\u003eConsistent cut rate maintained throughout brush life due to nonwoven material design\u003c\/li\u003e\n  \u003cli\u003eSuitable for use on ferrous and nonferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the 3M line of 1HP inline sanders and any tool accepting a 5\/8-11 threaded arbor mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator familiar with rotary abrasive tools. Before mounting, power down and disconnect the grinder or sander from its power source. Verify the tool spindle thread is 5\/8-11 and that the rated RPM of the tool does not exceed the maximum RPM rating of the brush. Always install and use per ANSI B7.1 safety standards for abrasive products, and wear appropriate eye and face protection during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 5A Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.89 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141557458\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7000121166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347586548018,"sku":"7000121166","price":147.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533744.jpg?v=1782108952","url":"https:\/\/voomisupply.com\/products\/3m-7000121166-flap-brush-4-5x4in-5a-medium-metal-finishing","provider":"Voomi Supply","version":"1.0","type":"link"}
