It measures 9 inches in diameter with a 0.063 inch thickness and a 1-1\/4 inch arbor hole. The resinoid bond holds the aluminum oxide grain securely during aggressive cuts, and the wheel is rated for a maximum of 4,025 RPM. At 0.308 pounds, it is well suited for high-volume production cutting or heavy shop use where consistent, straight cuts through medium steels are required. This wheel meets ML-309 specifications and is appropriate for steels in the Rockwell hardness range of approximately Rc 30 to 50.\u003c\/p\u003e\n\u003cp\u003eThis cutoff wheel is intended for use on stationary cutting equipment such as abrasive chop saws and cutoff machines found in metal fabrication shops, pipe fitting operations, and industrial maintenance environments. Its 9 inch diameter and Type 1 flat profile make it a standard replacement for shops cutting structural steel, bar stock, pipe, and similar ferrous materials. It is not designed for portable angle grinder use. Operators working in steel fabrication and mechanical contracting will find this a straightforward consumable for everyday ferrous cutting tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 (01\/41) flat profile for straight, controlled cutoff work on stationary machines\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain rated for cutting medium steels (Rc 30-50)\u003c\/li\u003e\n  \u003cli\u003eResinoid bond provides consistent grain exposure throughout wheel life\u003c\/li\u003e\n  \u003cli\u003e4,025 RPM maximum speed rating for stationary cutoff equipment\u003c\/li\u003e\n  \u003cli\u003eNon-reinforced construction at 0.063 inches thick for clean, narrow kerf cuts\u003c\/li\u003e\n  \u003cli\u003eMeets ML-309 specification for controlled abrasive performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with stationary abrasive cutoff tools accepting a 9 inch diameter, Type 1 wheel with a 1-1\/4 inch arbor hole.

Always power down and disconnect the machine before mounting or removing the wheel. Verify that the machine's operating RPM does not exceed the 4,025 RPM maximum stamped on the wheel before starting. Inspect the wheel for cracks or chips prior to each use and never use a damaged wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,025\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\u003eReinforced\u003c\/strong\u003e: Non-Reinforced\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steel (Medium Steels Rc 30-50)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ML-309\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.308 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66253117877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541495972146,"sku":"66253117877","price":52.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9b7375cfb360f06dd9d2ac0eb84fe2d.jpg?v=1785877800","url":"https:\/\/voomisupply.com\/products\/norton-66253117877-cutoff-wheel-9-in-aluminum-oxide-type-1","provider":"Voomi Supply","version":"1.0","type":"link"}
