At 150 grit with a Very Fine grade and Hardness Code T (Medium hardness rating), this wheel delivers controlled stock removal and refined surface finishes in one setup. The 12-inch diameter and 1\/4-inch superabrasive depth make it well-suited for surface grinder applications where consistent geometry and finish quality are required. Licensed grinding professionals and tool room machinists are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis CBN grinding wheel is used in surface grinding operations on hardened ferrous workpieces, including tool steels, high-speed steels, and similar difficult-to-grind materials. The resinoid bond provides a degree of self-dressing action and vibration damping, which supports both roughing and finishing passes. With a superabrasive concentration of 75 and the Norton CBN series designation CB150-TB99-1\/4, this wheel targets production and tool room environments where wheel life and dimensional consistency matter. It is suited for horizontal spindle surface grinders accepting a 5-inch hole and 12-inch diameter wheel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCBN (Cubic Boron Nitride) abrasive material for long wheel life on hardened ferrous metals\u003c\/li\u003e\n  \u003cli\u003eType 1A1 straight wheel geometry for use on horizontal spindle surface grinders\u003c\/li\u003e\n  \u003cli\u003e150 grit Very Fine grade produces refined surface finishes while maintaining stock removal capability\u003c\/li\u003e\n  \u003cli\u003eResinoid bond provides vibration damping and controlled self-dressing action\u003c\/li\u003e\n  \u003cli\u003eSuperabrasive concentration of 75 balances aggressiveness and wheel durability\u003c\/li\u003e\n  \u003cli\u003eNo recess, no taper — straightforward mounting on standard 5-inch hole arbors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for horizontal spindle surface grinders accepting a 12-inch diameter, 1\/2-inch thick Type 1A1 wheel with a 5-inch hole bore.

Always verify that the grinder spindle speed does not exceed the wheel's rated maximum RPM before mounting. Power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips prior to installation and never force the wheel onto the arbor — the fit should be snug without requiring impact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: CBN (Cubic Boron Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\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\u003eSeries Specification\u003c\/strong\u003e: CB150-TB99-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66260273560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541838201138,"sku":"66260273560","price":3150.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04bf3dace0535817157a8b72d97fe625.jpg?v=1785886438","url":"https:\/\/voomisupply.com\/products\/norton-66260273560-cbn-grinding-wheel-150-grit-12-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
