Built with a resinoid bond and a fine, 120-grit CBN abrasive, it delivers consistent stock removal on hard ferrous materials and hardened steels where conventional abrasives wear prematurely. The wheel measures 6 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. Hardness is rated Medium (code T), and the CBN superabrasive depth runs 1\/4 inch. It carries a 75 concentration rating, which balances wheel life with cut rate. Grinding technicians and tool-and-die professionals are the primary installers and users of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for roughing and cut-off operations on surface grinders in both shop and production environments. The Type 1A1 straight-wheel profile fits standard horizontal-spindle surface grinders. The resinoid bond performs well across a range of material hardness levels, and the CBN abrasive makes this wheel a practical choice for hardened tool steels, high-speed steels, and similar ferrous alloys that wear down aluminum oxide wheels rapidly. The 6-inch diameter and 1-1\/4 inch bore are common dimensions for bench and surface grinding machines found in machine shops and maintenance facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCBN (cubic boron nitride) abrasive for extended life on hardened ferrous materials\u003c\/li\u003e\n\u003cli\u003eType 1A1 straight-wheel profile fits horizontal-spindle surface grinders\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides good shock resistance and consistent performance\u003c\/li\u003e\n\u003cli\u003e120 grit, fine grade for controlled stock removal and improved surface finish\u003c\/li\u003e\n\u003cli\u003eMedium hardness (T) with 75 superabrasive concentration balances wheel life and cut rate\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward mounting on standard arbors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Type 1A1 straight CBN grinding wheel for use on horizontal-spindle surface grinders accepting a 6-inch diameter wheel with a 1-1\/4 inch arbor hole.

Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never exceed the rated maximum operating speed marked on the wheel. Flanges and blotters must be clean, flat, and correctly sized before tightening the arbor nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Cubic Boron Nitride (CBN)\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: 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: T (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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\u003eTaper\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\u003eMaterial Application\u003c\/strong\u003e: Roughing\/Cut-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Norton CBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: CB120-TB99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\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: 66260273605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539060654386,"sku":"66260273605","price":845.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4369a486463b2ffab8401dc1bb5c7659.jpg?v=1785833967","url":"https:\/\/voomisupply.com\/products\/norton-66260273605-cbn-surface-grinding-wheel-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
