Built on the 668X platform, it uses precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film substrate. The pressure-sensitive adhesive backing simplifies mounting to flat lapping plates, reducing setup time between abrasive changes. At 8 inches in diameter, this disc delivers a consistent, repeatable surface finish across a range of micron grades from 0.10 to 30.0 micron. It is used by precision machinists, optical technicians, and toolroom professionals who require controlled material removal and tight surface finish tolerances.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for lapping and polishing operations on ceramics, carbide, hardened steel, optical glass, and similar hard substrates. The PSA backing makes it compatible with standard flat lapping machines and rotary lapping fixtures that accept self-adhesive discs. Its consistent diamond particle distribution supports flat surface retention with minimal edge rounding, making it appropriate for both production and rework applications where geometry control is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for quick, secure mounting to lapping plates and fixtures\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond particles for consistent, repeatable finish results\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades ranging from 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003eFast cut rate supports increased throughput on hard materials\u003c\/li\u003e\n  \u003cli\u003eFlat surface geometry with low edge rounding\u003c\/li\u003e\n  \u003cli\u003eLong abrasive life reduces frequency of disc changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on extremely hard materials including ceramics, carbide, and hardened metals; compatible with flat lapping machines and rotary fixtures that accept 8-inch PSA-backed abrasive discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClean and dry the lapping plate surface before applying the PSA disc to ensure full adhesion and prevent slippage during operation. Press the disc firmly from the center outward to eliminate air pockets. Power down all rotating equipment completely before mounting or removing abrasive discs. Follow the machine manufacturer guidelines and applicable shop safety protocols when handling diamond abrasive products.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 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\u003eMicron Grade Range\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 7000044836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343031107890,"sku":"7000044836","price":940.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524068.jpg?v=1782014404","url":"https:\/\/voomisupply.com\/products\/3m-7000044836-diamond-lapping-film-disc-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
