Built with a resinoid bond and a black ceramic grain, it measures 4.5 inches in diameter and 0.045 inches thick, with a 7\/8-inch arbor hole for standard angle grinder spindle fitment. The thin kerf profile reduces material loss and heat buildup during cuts. At 0.08 pounds, this wheel is lightweight and well-suited for repetitive cutting tasks in fabrication, maintenance, and field service work. It is typically installed and used by machinists, pipefitters, ironworkers, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use with 4.5-inch angle grinders in both shop and field environments. Typical applications include cutting ferrous metals, structural steel, pipe, rod, and similar stock materials. The ceramic abrasive grain maintains a sharper cutting edge longer than conventional aluminum oxide, making it a practical choice for high-volume cutting in industrial and trade settings. This is a single-wheel package sold in a minimum order quantity of 50 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for extended cut life and cooler cutting action\u003c\/li\u003e\n\u003cli\u003e0.045-inch thin kerf reduces material waste and heat generation\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability under load and impact\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.08 pounds for reduced operator fatigue during extended use\u003c\/li\u003e\n\u003cli\u003eBlack wheel color for easy identification on the job site\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders equipped with a 7\/8-inch arbor spindle.

Always power down and disconnect the angle grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Use the appropriate guard for cutoff wheel operations as required by the tool manufacturer and applicable OSHA standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: 7100139230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51696344924466,"sku":"7100139230","price":309.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f2ca1df98dc082d03a1158e005fc59f.jpg?v=1788341708","url":"https:\/\/voomisupply.com\/products\/3m-7100139230-ceramic-cutoff-wheel-4-5-in-angle-grinder","provider":"Voomi Supply","version":"1.0","type":"link"}
