It measures 4 inches in diameter and 1\/32 inch thick, with a 3\/4 inch arbor hole. The wheel uses synthetic diamond (SD) abrasive bonded with a resinoid bond system and carries a specification designation of SD120-R100B99-1\/4. At 120 grit with a coarse grade and R hardness (soft wheel hardness rating), it is suited for aggressive stock removal on materials that require superabrasive tooling. The superabrasive depth is 1\/4 inch with a concentration of 100.\u003c\/p\u003e\u003cp\u003eThis wheel is used in surface grinding operations, typically on hard or brittle workpiece materials such as carbide, ceramics, glass, or hardened tool steels. The Type 1A1R form factor is a standard thin-rim configuration suited for cut-off and surface grinding tasks on bench or surface grinders. It is commonly used by tool and die shops, carbide tooling operations, and precision grinding technicians working with superabrasive wheel equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1A1R thin-rim wheel form for surface and cut-off grinding\u003c\/li\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive at 100 concentration for consistent material removal\u003c\/li\u003e\n\u003cli\u003e120 grit, coarse grade for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eResinoid bond system for controlled cut action\u003c\/li\u003e\n\u003cli\u003e1\/4 inch superabrasive depth for extended wheel life\u003c\/li\u003e\n\u003cli\u003eSpecification code SD120-R100B99-1\/4 for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit superabrasive surface grinding wheel for bench grinders and surface grinders accepting a 4 inch diameter, 3\/4 inch arbor hole, Type 1A1R wheel configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSuperabrasive grinding wheels must be installed by a qualified grinding technician or machinist following the wheel manufacturer and machine manufacturer safety guidelines. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before installation and verify that the machine RPM rating meets or exceeds the wheel speed rating. Do not use blotters or excessive clamping force that could damage the thin-rim structure of a Type 1A1R wheel.\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: 1\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Synthetic Diamond (SD)\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: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: SD120-R100B99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 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: 69014191706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542811771186,"sku":"69014191706","price":312.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cd35d11a520bc5ead324a201205d383.jpg?v=1785908094","url":"https:\/\/voomisupply.com\/products\/norton-69014191706-surface-grinding-wheel-4in-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
