With an 80-grit medium-grade abrasive and a maximum operating speed of 4500 RPM, it delivers consistent material removal and surface conditioning. The rectangular filament shape promotes uniform contact across the work surface. Arbor connector mounting makes it compatible with standard angle grinders and bench-mounted rotary tools. At 0.05 pounds, it is a lightweight consumable suited for repetitive production work or field service tasks.\u003c\/p\u003e\u003cp\u003eThis disc brush is used in metal fabrication shops, maintenance facilities, and field service environments where controlled surface finishing is required. It is appropriate for deburring, light rust removal, weld blending, and pre-treatment surface prep on ferrous and non-ferrous materials. The gray silicon carbide filament construction handles harder substrates that would wear down aluminum oxide media faster. A 1.25-inch trim length provides sufficient filament flex for contour work while maintaining abrasive control on flat stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch outside diameter for use with standard rotary tool arbors\u003c\/li\u003e\n\u003cli\u003e80-grit silicon carbide abrasive for medium-grade material removal\u003c\/li\u003e\n\u003cli\u003eMaximum rated speed of 4500 RPM for safe high-speed operation\u003c\/li\u003e\n\u003cli\u003e1.25-inch trim length with rectangular filament shape for consistent surface contact\u003c\/li\u003e\n\u003cli\u003eArbor connector mount compatible with common angle grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.05 pounds — suited for high-frequency use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with rotary tools and angle grinders equipped with a standard arbor connector accepting a 3-inch disc brush.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement should be performed by a qualified operator following the tool manufacturer's instructions. Always power down and disconnect the rotary tool before mounting or removing the disc brush. Confirm the tool's rated RPM meets or exceeds the brush's 4500 RPM maximum before operation. Inspect the filaments for wear or damage before each use and replace the brush when abrasive effectiveness is reduced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilament Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEILER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51543525916978,"sku":"85981","price":329.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3e4ac078d3b4d0b233b9e84f3063f96.jpg?v=1785919908","url":"https:\/\/voomisupply.com\/products\/weiler-85981-disc-brush-3-in-80-grit-silicon-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
