Measuring 1.5 inches in diameter and 0.035 inches thick with a 1\/4 inch arbor hole, this wheel is built for tight-access cutting where a larger wheel cannot reach. The resinoid bond holds 60-grit aluminum oxide abrasive in a side-reinforced construction, rated to a maximum of 40,745 RPM. Hardness code O indicates a medium-hard grade suited for controlled cut-off work on steel. Fabricators, pipefitters, and maintenance technicians reach for this wheel when precision and control matter more than aggressive stock removal.\u003c\/p\u003e\n\u003cp\u003eThis cutoff wheel is designed for use on steel with die grinders that accept a 1\/4 inch arbor. The 1.5 inch diameter and ultra-thin 0.035 inch kerf make it well-suited for detailed work such as cutting fasteners, small pipe sections, welds, and metal stock in confined spaces. The side-reinforced design adds structural integrity during high-speed operation. It carries specification designation A60-OBNA2, which identifies the abrasive type, grit, hardness, and bond for shops that track wheel specifications on job cards or maintenance logs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 (flat) profile with side reinforcement for added wheel integrity at speed\u003c\/li\u003e\n  \u003cli\u003e60-grit aluminum oxide abrasive suited for cutting steel\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 40,745 RPM for compatibility with standard die grinders\u003c\/li\u003e\n  \u003cli\u003eUltra-thin 0.035 inch kerf minimizes material loss and heat buildup\u003c\/li\u003e\n  \u003cli\u003eResinoid bond with hardness code O for consistent, controlled cut-off performance\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch arbor hole fits standard die grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders accepting a 1\/4 inch arbor.

Inspect the wheel for cracks or chips before mounting and never use a damaged wheel. Wear appropriate face and eye protection and ensure all bystanders are clear of the cutting plane. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (01\/41)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 40,745\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: O\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReinforcement\u003c\/strong\u003e: Sides Reinforced\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: A60-OBNA2\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: 23131503\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66243427875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544453644594,"sku":"66243427875","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed6b8ed2ea43803be605e94369f5e0d6.jpg?v=1785926990","url":"https:\/\/voomisupply.com\/products\/norton-66243427875-cutoff-wheel-1-1-2-in-aluminum-oxide-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
