It measures 20 inches in diameter, 1 inch thick, with a 12-inch hole size, and carries a 120 grit Fine grade for controlled material removal. The abrasive section uses Armored Synthetic Diamond (ASD) with a superabrasive depth of 0.25 inches and a concentration rating of 75. The resinoid bond provides consistent performance under wet operating conditions. This wheel is part of the Norton ASD series and is used by machinists and surface grinding professionals in production and toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding applications requiring a fine grit finish on hard or brittle workpieces. The Type 1A1 flat wheel profile fits horizontal spindle surface grinders configured for large-diameter tooling. With a 12-inch arbor hole, it is intended for heavy-duty machine spindles common in industrial production settings. The wet operation designation means it is designed to run with coolant, which aids chip evacuation and prolongs wheel life during roughing and cut-off work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eArmored Synthetic Diamond (ASD) abrasive for cutting hard and brittle materials\u003c\/li\u003e\n  \u003cli\u003e120 grit Fine grade for controlled stock removal with a refined surface finish\u003c\/li\u003e\n  \u003cli\u003eResinoid bond optimized for wet grinding operation with coolant\u003c\/li\u003e\n  \u003cli\u003eType 1A1 flat wheel geometry with no recess and no taper\u003c\/li\u003e\n  \u003cli\u003eSuperabrasive concentration of 75 and depth of 0.25 inches for consistent abrasive exposure\u003c\/li\u003e\n  \u003cli\u003eSoft hardness rating (R) reduces loading on difficult-to-grind materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on horizontal spindle surface grinders accepting a Type 1A1 flat wheel with a 20-inch diameter and 12-inch arbor hole.

Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before mounting, and never exceed the maximum operating speed marked on the wheel. Confirm coolant flow is established before beginning wet grinding operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R (Soft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Armored Synthetic Diamond (ASD)\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 1A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperabrasive Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Roughing\/Cut-Off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: ASD120-R75B99-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.64 pounds\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: 69014192325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540289683762,"sku":"69014192325","price":3997.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c868e75149aefd7633fae22471a9246f.jpg?v=1785851308","url":"https:\/\/voomisupply.com\/products\/norton-69014192325-surface-grinding-wheel-120-grit-20-in","provider":"Voomi Supply","version":"1.0","type":"link"}
