Built on a dimensionally stable polyester film base, it carries precisely graded diamond abrasive particles that deliver consistent, repeatable results across multiple passes. The disc measures 2 inches in diameter and is rated at 1.0 micron particle size, placing it in the fine-finishing range. It is used by technicians and machinists who require tight surface-finish tolerances on hard substrates such as ceramics, carbide, optical components, and hardened tool steel.\u003c\/p\u003e\u003cp\u003eThis disc is suited for bench lapping, fixture-mounted lapping, and handheld finishing operations where a PSA backing is needed for quick mounting to a flat or backed platen. The 1.0 micron grade is appropriate for final or near-final finishing stages where surface roughness must be minimized without aggressive material removal. Trades and industries that commonly use this product include optical fabrication, precision machining, fiber-optic connector polishing, and tool and die work. The PSA backing simplifies disc changes and reduces setup time compared to non-adhesive film products.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecisely graded 1.0 micron diamond abrasive particles for fine, repeatable surface finishes\u003c\/li\u003e\n\u003cli\u003ePSA backing for fast, secure mounting to compatible platens or backing pads\u003c\/li\u003e\n\u003cli\u003ePolyester film base provides dimensional stability under lapping pressure\u003c\/li\u003e\n\u003cli\u003e2-inch disc diameter fits standard lapping fixtures and handheld backing plates\u003c\/li\u003e\n\u003cli\u003eSuitable for extremely hard materials including ceramics, carbide, and hardened metals\u003c\/li\u003e\n\u003cli\u003eAvailable across a broad grade range from 0.10 to 30.0 micron for multi-stage finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 2-inch PSA-compatible lapping platens, backing pads, and fixtures used in precision surface-finishing operations on hard substrates.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eClean the platen or backing pad surface thoroughly before applying the PSA disc to ensure full adhesion and prevent disc slippage during use. Apply firm, even pressure across the disc face when mounting to eliminate air pockets. Follow all facility safety protocols for handling fine abrasive materials, including eye protection. Dispose of used discs according to applicable workplace safety guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle Size\u003c\/strong\u003e: 1.0 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 2 inches\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 Base\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Grade Range\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\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111546901\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7100048137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346521751858,"sku":"7100048137","price":244.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524247.jpg?v=1782082667","url":"https:\/\/voomisupply.com\/products\/3m-7100048137-diamond-lapping-film-psa-disc-1-0-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
