Built from zirconia alumina abrasive with a resinoid bond, this wheel delivers aggressive stock removal and extended service life compared to standard aluminum oxide wheels. At 4 inches in diameter and just 0.035 inches thick, it produces narrow kerfs that minimize material loss and reduce heat buildup at the cut. The wheel is rated to 19,100 RPM and carries reinforcement on both sides for added structural integrity during high-speed operation. Grit is 46, placing it firmly in the coarse range for rapid cutting rather than finishing. Metalworking professionals and fabricators are the primary installers of this consumable.\u003c\/p\u003e\u003cp\u003eThis cutoff wheel is suited for light-to-moderate cutting tasks on ferrous and non-ferrous metals, including structural steel and stainless steel tube, sheet, and bar stock. The 3\/8 inch arbor hole fits standard small-angle grinder spindles common in field and shop environments. The Bluefire specification designation indicates Norton's zirconia alumina grain blend formulated for extended cut-rate consistency on tough metals. It is packaged as a single wheel, making it practical for spot replenishment or low-volume use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina abrasive grain for aggressive cutting and longer wheel life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eType 1 flat profile produces straight, narrow kerfs with minimal burr\u003c\/li\u003e46 coarse grit rated for rapid material removal\u003cli\u003eDual-sided reinforcement adds structural support at high operating speeds\u003c\/li\u003e\n\u003cli\u003e19,100 RPM maximum speed rating compatible with standard small angle grinders\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides consistent grain exposure throughout wheel life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders accepting a 3\/8 inch arbor and capable of accommodating a 4 inch diameter cutoff wheel.

Before mounting, inspect the wheel for cracks, chips, or damage and discard any compromised wheel. Ensure the grinder is unplugged or the battery removed before changing wheels. Do not exceed the maximum RPM stamped on the wheel, and always use the guard supplied with the grinder per ANSI B7.1 safety requirements.\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: 0.035 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: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 19,100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced\u003c\/strong\u003e: Yes, sides reinforced\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\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: Bluefire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.047 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66252843173\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540314292530,"sku":"66252843173","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84f8873514eea4c8401fb01bae749184.jpg?v=1785851953","url":"https:\/\/voomisupply.com\/products\/norton-66252843173-type-1-cutoff-wheel-4in-zirconia-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
