The roll measures 4 inches wide by 150 feet long with a 3-inch core and is manufactured to a 15-micron abrasive grade, delivering consistent, repeatable scratch patterns on close-tolerance surfaces. The keyed core (ASO) design locks the roll into compatible lapping fixtures and machines, preventing slippage during operation. Machinists, tool-and-die technicians, and precision grinding professionals typically work with this consumable in controlled finishing environments.\u003c\/p\u003e\u003cp\u003eThis microfinishing film is suited for lapping, honing, and fine-surface refinement on metal components where dimensional accuracy and surface finish quality are critical. The 15-micron grade is positioned for intermediate to fine finishing stages, removing minor surface irregularities while maintaining tight tolerances. It performs on a range of metallic substrates in both production-line and job-shop settings. Each case contains 4 rolls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15-micron abrasive grade for intermediate to fine precision finishing\u003c\/li\u003e\n\u003cli\u003e4 inches wide by 150 feet long roll format for extended production use\u003c\/li\u003e\n\u003cli\u003e3-inch ASO keyed core prevents roll slippage in compatible lapping equipment\u003c\/li\u003e\n\u003cli\u003eConsistent abrasive coating delivers repeatable surface finish results\u003c\/li\u003e\n\u003cli\u003eSold in cases of 4 rolls (minimum order quantity: 4)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with lapping and microfinishing machines that accept a 3-inch ASO keyed core roll format.
