Built on the 668X platform, it uses precisely graded diamond particles coated onto a polyester film substrate. The pressure-sensitive adhesive backing allows fast, tool-free mounting to compatible lapping plates and holders. Available in grades ranging from 0.10 to 30.0 micron, this disc delivers a consistent, repeatable surface finish with flat geometry and minimal edge rounding. It is suited for applications where surface quality and dimensional control are critical.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in precision grinding, lapping, and polishing applications across industries that require tight surface finish tolerances on hard substrates such as ceramics, carbides, optical components, and hardened metals. The PSA backing makes it practical for production environments where frequent abrasive changes are common and downtime must be minimized. Its long abrasive life and fast cut rate support increased throughput on flat-surface finishing operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for tool-free mounting and quick disc changes\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond abrasive particles for consistent, repeatable finishes\u003c\/li\u003e\n  \u003cli\u003eFlat surface geometry with low edge rounding\u003c\/li\u003e\n  \u003cli\u003eFast cut rate supports higher throughput in production settings\u003c\/li\u003e\n  \u003cli\u003eLong abrasive life reduces the frequency of abrasive changes\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades from 0.10 to 30.0 micron to suit varying finish requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard lapping disc for use with compatible PSA-style flat lapping plates, holders, and precision finishing equipment that accept 4-inch diameter PSA-backed abrasive discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClean the lapping plate or backing surface thoroughly before applying the PSA disc to ensure full adhesion and prevent slippage during use. Press the disc firmly and evenly onto the plate, starting from the center and working outward to eliminate air pockets. Power down or de-energize any motorized lapping equipment before mounting or removing abrasive discs. Follow the equipment manufacturer's guidelines for disc speed ratings and loading pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilm Substrate\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Grades\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010298833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345825038642,"sku":"7010298833","price":492.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524256.jpg?v=1782063978","url":"https:\/\/voomisupply.com\/products\/3m-7010298833-diamond-lapping-film-disc-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
