3M 7000044825 Diamond Lapping Film 0.50 Micron Sheet

Product Description

The 3M 7000044825 is a precision diamond lapping film sheet designed for ultra-fine surface finishing of extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, producing a consistent, repeatable finish across each pass. The sheet measures 9 inches x 11 inches and carries a 0.50 micron abrasive grade, placing it in the ultra-fine range suited for final-stage lapping and polishing operations. This product is used by trade professionals requiring tight surface finish tolerances on hard substrates including ceramics, carbide, optical components, and fiber optic end faces.

This lapping film is applied in precision finishing operations where surface finish consistency is critical. Typical applications include lapping flat surfaces on valve seats, ceramic components, optical fiber connectors, and hard metal tool faces. The 9 inches x 11 inches sheet format is compatible with hand lapping on flat plates as well as fixture-guided lapping setups. It is sold in individual sheet units with a minimum order quantity of 10 sheets, making it appropriate for shop stock or service kit replenishment.
