3M 7000008835 Diamond Lapping Film Disc 8 Inch

Product Description

The 3M 7000008835 is an 8-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a durable polyester film substrate, delivering a consistent and repeatable finish across each use. This disc is suited for applications where tight surface tolerances and uniform scratch patterns are required. Licensed trades and precision finishing technicians working with ceramics, carbides, glass, and similar hard substrates rely on this disc format for controlled material removal and edge definition.

This diamond lapping film disc is used in precision lapping and polishing operations across optical, ceramic, carbide tooling, and hard material finishing applications. It is available in several grades ranging from 0.10 to 30.0 micron, allowing technicians to progress through finishing sequences to achieve target surface quality. The disc format is compatible with standard lapping fixtures and rotary finishing equipment. It is sold individually and is suited for both production and service environments requiring repeatable, high-quality results on demanding materials.
