It measures 12 inches in diameter with a 0.075-inch thickness and accepts a 1-1\/4-inch arbor hole, making it compatible with standard stationary grinders. The wheel is resinoid-bonded with a 60-grit aluminum oxide abrasive and carries an O hardness rating, delivering a balance of cut rate and wheel life suited to production and heavy-duty shop environments. Both sides are reinforced for added durability under lateral stress. Maximum rated speed is 5,095 RPM. This wheel is installed and operated by metalworkers, fabricators, and maintenance trades using stationary cutoff machines.\u003c\/p\u003e\u003cp\u003eThis cutoff wheel is intended for use on stationary grinders in shop and fabrication settings. It is well suited for cutting steel stock, bar stock, pipe, and structural shapes in both light industrial and heavy fabrication applications. The 12-inch diameter and 60-grit specification make it appropriate for production cutting where consistent results on ferrous metal are required. This is not a portable angle grinder wheel — it is rated for stationary equipment only.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-inch diameter Type 1 flat profile for straight cutoff work on stationary grinders\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive at 60 grit for efficient material removal on steel\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability and resistance to shock loads during cutting\u003c\/li\u003e\n\u003cli\u003eBoth sides reinforced for additional structural integrity\u003c\/li\u003e\n\u003cli\u003eO hardness grade balances wheel longevity with consistent cut performance\u003c\/li\u003e\n\u003cli\u003e5,095 RPM maximum speed rating for stationary grinder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with stationary grinders.

Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel. Ensure the machine's spindle speed does not exceed the wheel's 5,095 RPM maximum rating, and use the correct flanges and arbor hardware as specified by the grinder manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.075 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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: 5,095\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: Yes, both sides\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66253261858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540670939442,"sku":"66253261858","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/361accb0c4464de63c42d3f8a6e9fd74.jpg?v=1785861470","url":"https:\/\/voomisupply.com\/products\/norton-66253261858-aluminum-oxide-cutoff-wheel-12-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
