3M Diamond Lapping Film 4 Inch 3um (50 Pack)

Overview

3M Diamond Lapping Films consist of precision-graded diamond mineral particles uniformly coated onto a durable polyester film backing. These films are engineered to deliver consistent, repeatable polishing results for fiber optic connectors, ensuring reliable performance in demanding network environments.

Designed to provide a high-quality surface finish, these lapping films reduce process times and improve yields by eliminating the need for messy liquid slurries. Their robust construction supports a long abrasive life, making them a cost-effective choice for both field and laboratory fiber optic termination applications.

Key Features
