The 747D designation identifies a heavy-duty X-weight cloth backing paired with an 80-grit aluminum oxide abrasive, a combination suited for aggressive stock removal on metal, wood, and composite surfaces. Each band measures 1 inch wide by 1 inch long, sized for use on spindle sanders, drum sanders, and similar bench or portable abrasive tools. The case contains 100 bands, making it a working supply quantity appropriate for shop or field use by machinists, pipefitters, HVAC technicians, and general trade contractors who need consistent cut rate across high-volume finishing operations.\u003c\/p\u003e\u003cp\u003eThese bands are well suited for deburring pipe ends, cleaning weld seams, shaping contoured workpieces, and surface preparation before coating or assembly. The X-weight backing resists tearing under load, which is critical when running at elevated RPM on motorized spindle tools. HVAC and plumbing tradespeople commonly use bands in this size and grit range for cleaning copper fittings, deburring steel pipe ends, and preparing metal surfaces ahead of brazing or mechanical joining. The 80-grit cut is aggressive enough to remove oxidation and light scale without excessive material loss on softer metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-grit abrasive rating for aggressive stock removal and surface preparation\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides high tensile strength and tear resistance under load\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch band size fits standard spindle and drum sanding mandrels\u003c\/li\u003e\n\u003cli\u003e747D cloth construction designed for consistent cut rate throughout band life\u003c\/li\u003e\n\u003cli\u003e100-band case quantity supports high-volume shop or jobsite use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with spindle sanders, drum sanders, and rotary abrasive tools that accept 1 inch x 1 inch abrasive bands.

Ensure the mandrel diameter matches the band inside diameter for a secure, wobble-free fit before operating. Inspect each band for tears or delamination before use, and replace bands that show signs of glazing or reduced cut rate. Follow the tool manufacturer's maximum RPM specifications to avoid band failure during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X-weight cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Case\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144807741\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: 7100138166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343089664306,"sku":"7100138166","price":146.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534722.jpg?v=1782016275","url":"https:\/\/voomisupply.com\/products\/3m-7100138166-cloth-band-747d-80-grit-1x1-inch-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
