Built on a flexible cloth backing, this disc mounts directly to PSA-compatible backup pads without fasteners or hook-and-loop systems. The 120-grit diamond abrasive delivers fine-grade cutting action suited for grinding, lapping, and finishing operations where consistent scratch patterns and long abrasive life are required. The flexible cloth substrate conforms to slightly contoured surfaces, reducing pressure variation across the contact area. Machinists, tool-and-die technicians, and surface finishing professionals are the typical end users for this disc type.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in bench grinding, surface preparation, and precision lapping applications across metalworking, composite fabrication, and stone or ceramic finishing environments. The diamond abrasive material makes it well suited for hard-to-grind substrates including carbide, ceramics, glass, and hardened steel. It is compatible with 5-inch PSA backup pads and rotary finishing tools configured for that diameter. No vacuum holes are present, so this disc is intended for use on solid backup pads rather than dust-extraction systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-grit diamond abrasive for fine-grade material removal and surface finishing\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive adhesive backing mounts directly to PSA-compatible pads\u003c\/li\u003e\n  \u003cli\u003eFlexible cloth backing conforms to mildly contoured work surfaces\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — designed for solid backup pad use\u003c\/li\u003e\n  \u003cli\u003eBlack disc color; part of the NORTON D71S series\u003c\/li\u003e\n  \u003cli\u003eSuited for hard substrates including carbide, ceramics, and hardened steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5-inch PSA backup pads on rotary grinders, sanders, and lapping machines.

Power down and de-energize the tool before mounting or removing any abrasive disc. Press the disc firmly onto the backup pad from center to edge to eliminate air pockets. Inspect the disc for tears or delamination before each use and replace immediately if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\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: Black\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: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66260307838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538302763314,"sku":"66260307838","price":148.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45a4b12c7510800431c1447b3a50baa4.jpg?v=1785822371","url":"https:\/\/voomisupply.com\/products\/norton-66260307838-psa-disc-5-in-120-grit-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
