At 1-1\/2 inches in diameter and 0.035 inches thick, this thin-kerf wheel is reinforced on both sides with a resinoid bond for controlled, clean cutting in tight spaces. The 1\/16-inch arbor hole fits standard die grinder mandrels. With a maximum operating speed of 40,745 RPM and a 60-grit hardness code O formulation, it delivers aggressive material removal on ferrous stock without excessive wheel deflection. Licensed trades and fabricators rely on this wheel for precise notching, slotting, and cut-off work on steel pipe, rod, and bar stock.\u003c\/p\u003e\n\u003cp\u003eThis cutoff wheel is suited for handheld die grinder applications in industrial, mechanical, and trade environments. Its compact 1-1\/2-inch diameter makes it practical for confined-space cutting on steel components where larger wheels cannot reach. Typical applications include HVAC fabrication, plumbing rough-in metalwork, electrical conduit notching, and general maintenance cutting on steel substrates. The reinforced construction handles the lateral stresses common in die grinder use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 (flat) profile for straight cut-off work on steel\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with 60 grit for aggressive ferrous cutting\u003c\/li\u003e\n  \u003cli\u003eBoth sides reinforced with resinoid bond for added structural integrity\u003c\/li\u003e\n  \u003cli\u003e40,745 maximum RPM rating matches high-speed die grinder spindles\u003c\/li\u003e\n  \u003cli\u003e0.035-inch thin kerf minimizes material loss and heat buildup\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch arbor hole fits standard die grinder mandrel shanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders.

Always power down and disconnect the die grinder before changing wheels. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. Wear appropriate eye and face protection, and ensure bystanders are clear of the cutting plane during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 1-1\/2 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\u003eArbor Hole Size\u003c\/strong\u003e: 1\/16 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\u003eReinforced\u003c\/strong\u003e: Both 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 Code\u003c\/strong\u003e: A60-OBNA2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66243427764\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541402353970,"sku":"66243427764","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f02e6ee63c2ffca6709ddc1d3e639f70.jpg?v=1785874954","url":"https:\/\/voomisupply.com\/products\/norton-66243427764-cutoff-wheel-1-1-2-in-aluminum-oxide-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
