3M-266X Imp. Lapping Film PSA

The 3M™ Lapping Film 266X was developed for maximum precision in fine grinding and polishing applications and ensures reproducible, uniform surface quality. The homogeneous, non-compressible polyester film backing with a full synthetic resin bond ensures reliable stability and consistent removal rate. Thanks to its tight grain distribution and excellent grain adhesion, the film delivers a defined, consistently high grinding performance without clogging—ideal for demanding applications involving hard materials.

Coated with aluminum oxide and available in multiple micron grit sizes ranging from 0.3 to 40 μm, the Lapping Film enables precise removal, deburring, finishing, and polishing. Color coding ensures easy identification of grit sizes, while the water- and oil-resistant design offers versatile application possibilities. The self-adhesive PSA backing facilitates attachment to suitable backing plates and contributes to comfortable handling in daily use. With a long service life and a uniform finish, the 3M™ Lapping Film 266X is a reliable choice for industrial precision machining.
