Measuring 4 inches in diameter and 0.04 inches thick with a 3\/8-inch arbor hole, this wheel is built for use with die grinders in production and maintenance cutting applications. Both sides are fiberglass-reinforced for added integrity during high-speed operation. The wheel is rated to a maximum of 19,100 RPM and carries a hardness code of O, indicating a medium-hard bond suitable for cutting mild and carbon steel stock.\u003c\/p\u003e\u003cp\u003eThis cutoff wheel is suited for professional tradespeople and fabricators who work with die grinders in tight-clearance or detail cutting situations. The 4-inch diameter and thin 0.04-inch kerf make it effective for cutting bolts, rod stock, pipe, and sheet metal sections where minimal material removal is needed. The aluminum oxide abrasive at 60 grit delivers consistent cut initiation on ferrous materials in both shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 (flat) profile for straight-line cutoff applications\u003c\/li\u003e\n\u003cli\u003e60-grit aluminum oxide abrasive optimized for steel cutting\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability at high operating speeds\u003c\/li\u003e\n\u003cli\u003eBoth sides fiberglass-reinforced for structural integrity\u003c\/li\u003e\n\u003cli\u003eThin 0.04-inch wheel thickness minimizes kerf and heat buildup\u003c\/li\u003e\n\u003cli\u003eRated to 19,100 RPM for compatibility with standard die grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with die grinders accepting a 3\/8-inch arbor hole.

Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately. Wear appropriate eye, face, and hand protection during operation. Ensure the guard is in place on the grinder before starting the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3\/8 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: 19,100\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: Both sides reinforced\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: A60-OBNA2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Brown\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\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: 66243529516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540393394482,"sku":"66243529516","price":19.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae019d79eab56aa0f814bc7c1af55923.jpg?v=1785854087","url":"https:\/\/voomisupply.com\/products\/norton-66243529516-cutoff-wheel-4-in-60-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
