Running a 400-grit diamond abrasive on a flexible cloth backing, this disc delivers extra fine material removal suited for hard, dense surfaces where conventional aluminum oxide or silicon carbide abrasives wear down quickly. The yellow disc mounts directly to PSA-compatible backing pads without clips or mechanical fasteners. It is part of the D71S series and is used by machinists, tool grinders, and surface finishing professionals who require consistent, controlled stock removal at fine grits.\u003c\/p\u003e\u003cp\u003eThis disc is well suited for grinding, lapping, and finishing operations on hard materials such as carbide, ceramics, glass, stone, and hardened steel. The flexible cloth backing conforms slightly to contoured surfaces, making it practical for both flat and mildly irregular workpieces. The 400-grit extra fine rating places it in the final stages of a progressive abrasive sequence, typically following coarser grits to refine surface finish and reduce scratch depth before polishing. No vacuum holes are included, so it is intended for use without dust extraction through the disc itself.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400-grit diamond abrasive for extra fine surface finishing on hard materials\u003c\/li\u003e\n\u003cli\u003e6-inch diameter fits standard PSA backing pads\u003c\/li\u003e\n\u003cli\u003eFlexible cloth backing allows slight conformability to workpiece geometry\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount for fast disc changes without mechanical hardware\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid backing pad setups\u003c\/li\u003e\n\u003cli\u003eYellow disc color for easy grit identification in multi-disc workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 6-inch PSA-compatible backing pads on bench grinders, surface grinders, or rotary finishing tools that accept adhesive-mount abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePower down and lock out the grinding or finishing machine before changing discs. Ensure the backing pad surface is clean and free of adhesive residue from previous discs before applying the new PSA disc, as contamination reduces bond strength. Press the disc firmly onto the backing pad from center outward to eliminate air pockets. Diamond abrasive discs should be used with appropriate coolant or dry as recommended for the workpiece material — consult tooling manufacturer guidelines for operating speed limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: D71S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 66260308161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541158166834,"sku":"66260308161","price":109.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45387a5a5eacbd01f61f30c8875af112.jpg?v=1785869195","url":"https:\/\/voomisupply.com\/products\/norton-66260308161-psa-disc-6-in-400-grit-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
