Diamond mineral is bonded to a durable polyester film backing, delivering consistent cutting action and surface refinement across a range of demanding substrates. The roll measures 4 inches wide by 50 feet long with a 3-inch core, and the abrasive grade is 45 micron. This product is used by skilled machinists, toolroom technicians, and surface finishing specialists who require tight tolerances and repeatable results on hard surfaces.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is suited for superfinishing applications on hard materials including thermal spray coatings, ceramics, carbides, chilled iron, and granite. It is appropriate for use in precision grinding, lapping, and honing operations where conventional abrasives fail to achieve the required surface finish or cut rate. The film backing provides dimensional stability, making it compatible with automated and semi-automated finishing equipment as well as hand-guided applications on flat and contoured workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond mineral abrasive bonded to polyester film backing for consistent cut and long service life\u003c\/li\u003e\n  \u003cli\u003e45 micron abrasive grade for aggressive material removal combined with controlled surface finishing\u003c\/li\u003e\n  \u003cli\u003e4 inches x 50 ft roll with 3-inch core fits standard finishing equipment and roll holders\u003c\/li\u003e\n  \u003cli\u003eEffective on thermal spray coatings, ceramics, carbides, chilled iron, and granite\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability for flat and contoured surface work\u003c\/li\u003e\n  \u003cli\u003eDesigned for superfinishing and fast finish reduction in precision machining environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on hard materials including thermal spray coatings, ceramics, carbides, chilled iron, and granite.
