It measures 5 inches in diameter with a 0.015 inch thickness and a 1\/2 inch hole, making it a thin-rim cutoff and grinding wheel suited for hard, brittle materials. The abrasive is Armored Synthetic Diamond (ASD) at 100 concentration, bonded in a metal bond matrix with a fine grade and medium hardness (N). At 220 grit, this wheel delivers a fine finish pass on ceramics, carbide, glass, and similar workpiece materials. It is handled and installed by machinists, tool-and-cutter grind technicians, and industrial maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is used in surface grinding operations where tight tolerances and fine surface finishes are required on hard or brittle workpiece materials. Typical applications include grinding tungsten carbide, ceramics, glass, and hardened ferrous or non-ferrous materials. The metal bond construction and 1\/8 inch superabrasive depth make it well-suited for production surface grinding on rotary and reciprocating surface grinders. The 100 concentration rating delivers consistent stock removal with controlled wear across the abrasive rim.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1A1R thin-rim diamond wheel for precision surface grinding\u003c\/li\u003e\n\u003cli\u003eArmored Synthetic Diamond (ASD) abrasive at 100 concentration for consistent cut rate\u003c\/li\u003e\n\u003cli\u003e220 grit fine grade for smooth finish passes on hard materials\u003c\/li\u003e\n\u003cli\u003eMetal bond matrix with medium hardness (N) for controlled wheel wear\u003c\/li\u003e\n\u003cli\u003e1\/8 inch superabrasive depth provides extended wheel life\u003c\/li\u003e\n\u003cli\u003eSpecification code M4D220-N100M99-1\/8 for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard-production diamond grinding wheel for surface grinders accepting a 5 inch diameter, 1\/2 inch arbor hole, Type 1A1R wheel form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and dressing of diamond grinding wheels should be performed by a qualified machinist or grinding technician. Always power down and lock out the grinder before mounting or removing the wheel, and inspect the wheel for visible damage or cracks before use. Follow ANSI B7.1 safety standards for wheel mounting, flanges, and guard clearances. Do not exceed the wheel's rated maximum operating speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 220\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: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Type\u003c\/strong\u003e: Armored Synthetic Diamond (ASD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Depth\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: M4D220-N100M99-1\/8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: 69014192070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542014001458,"sku":"69014192070","price":556.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5b4e8bff08962c259469b0e95ff7d93.jpg?v=1785889609","url":"https:\/\/voomisupply.com\/products\/norton-69014192070-surface-grinding-wheel-220-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
