It uses aluminum oxide abrasive nylon fill to deliver consistent cutting action without loading or glazing. The 1\/8-inch shank mounts directly into rotary tools, die grinders, and flexible-shaft machines, making it a practical choice for technicians working on fittings, ports, threads, and small weld zones. Rated to 6,000 RPM, this brush is suited for controlled-speed finish work rather than high-speed aggressive grinding. At 0.012-inch wire diameter and 600 grit, it produces a fine, consistent scratch pattern.\u003c\/p\u003e\n\u003cp\u003eThis cup brush is used in applications where a standard wheel brush or flap disc is too large to access the work area. Common scenarios include cleaning burrs from tubing ends, prepping copper or aluminum surfaces before brazing, and conditioning small metal components in HVAC, plumbing, and general fabrication work. The fine grit and aluminum oxide fill also make it appropriate for light finishing passes on non-ferrous metals where contamination from steel wire must be avoided.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive nylon fill for consistent surface conditioning without metal contamination\u003c\/li\u003e\n  \u003cli\u003e0.012-inch wire diameter and 600 grit for fine, controlled scratch patterns\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch straight shank fits standard rotary tools and die grinders\u003c\/li\u003e\n  \u003cli\u003e6,000 RPM maximum speed rating for controlled-speed applications\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch brush diameter accesses confined areas and small bore openings\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.06 pounds — minimal tool loading during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rotary tools, die grinders, and flexible-shaft machines accepting a 1\/8-inch straight shank.

Verify the tool is rated to run at or above 6,000 RPM and that the collet is fully tightened to prevent slippage. Always wear eye protection and appropriate PPE when operating abrasive brushes. Do not exceed the 6,000 RPM maximum speed rating marked for this brush.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Type\u003c\/strong\u003e: Straight Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Type\u003c\/strong\u003e: Straight Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: OSBORN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0007570700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSBORN","offers":[{"title":"Default Title","offer_id":51727070527794,"sku":"0007570700","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7420398a63b302ccb0ced546be5df616.jpg?v=1788672781","url":"https:\/\/voomisupply.com\/products\/osborn-0007570700-cup-brush-9-16-in-aluminum-oxide-6000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
