Precisely graded diamond abrasive particles are bonded to a dimensionally stable polyester film substrate, producing a consistent, repeatable finish across every pass. The 3.0 micron grade makes this disc suitable for intermediate lapping and polishing stages where tight surface tolerances are required. Technicians working with carbide tooling, ceramic components, optical substrates, fiber optic ferrules, and similarly hard workpieces rely on this format for controlled material removal and surface refinement.\u003c\/p\u003e\u003cp\u003eThis disc is sized at 4 inches in diameter and is sold individually. It fits into production and field lapping workflows where a no-hub attachment format is specified. The 3.0 micron rating positions it in the finer end of the abrasive sequence, typically used after coarser stock-removal stages to refine the surface before final polishing. It is well suited to controlled bench work in optical, metrology, tooling, and precision mechanical applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.0 micron diamond abrasive grade for fine lapping and intermediate polishing\u003c\/li\u003e\n\u003cli\u003ePrecisely graded particles deliver consistent, repeatable surface finish\u003c\/li\u003e\n\u003cli\u003ePolyester film backing provides dimensional stability under controlled lapping pressure\u003c\/li\u003e\n\u003cli\u003e4-inch disc format fits standard lapping fixtures and holders\u003c\/li\u003e\n\u003cli\u003eEffective on carbide, ceramic, optical glass, and other extremely hard materials\u003c\/li\u003e\n\u003cli\u003ePart of a broader grade range spanning 0.10 to 30.0 micron for full-sequence lapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 4-inch lapping disc fixtures and holders in precision finishing applications involving extremely hard materials such as carbide, ceramics, and optical substrates.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the disc to the lapping plate or fixture per the holder manufacturer's instructions before applying any workpiece pressure. Ensure the lapping surface and workpiece are clean and free of contamination from coarser abrasive grades before switching to this film. This abrasive film is intended for use by technicians familiar with precision lapping procedures and appropriate fixturing techniques.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 3.0 micron\u003c\/li\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 Material\u003c\/strong\u003e: Polyester film\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\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: 7000044733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346171167026,"sku":"7000044733","price":401.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524303.jpg?v=1782072797","url":"https:\/\/voomisupply.com\/products\/3m-7000044733-diamond-lapping-film-disc-3-0-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
