3M 7000000260 Diamond Lapping Film 6.0 Micron Sheet

Product Description

The 3M 7000000260 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. It features precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing. The 6.0 micron grade delivers a consistent, repeatable finish across demanding applications. Each sheet measures 4.50 inches x 4.50 inches and weighs approximately 0.01 pounds. This product is used by precision machinists, tool and die technicians, fiber optic technicians, and trade professionals who require controlled, fine material removal on hard substrates such as carbide, ceramic, glass, and hardened steel.

Diamond lapping film at the 6.0 micron grade is well suited for intermediate to fine finishing stages where tight surface tolerances are required. Typical applications include lapping and polishing of fiber optic connectors, carbide tooling, ceramic components, and other hard, wear-resistant materials. The polyester film backing provides a uniform, flexible base that conforms slightly to the work surface, helping maintain consistent abrasive contact. This sheet format works with flat lapping plates, backing pads, and hand-lapping fixtures common in precision finishing workflows.

Key Features

Compatibility

Designed for use on extremely hard materials requiring precision abrasive finishing. Compatible with flat lapping plates, hand-lapping fixtures, and backing pads that accept sheet-format lapping film. Specific model compatibility was not provided in available product data.

Installation Notes

Diamond lapping film is typically applied by precision finishing technicians and fiber optic or tooling specialists. Secure the sheet firmly to a flat lapping plate or appropriate backing pad before use to prevent slipping and ensure even abrasive contact. Work in a clean environment to avoid contamination of the abrasive surface, which can affect finish quality. Follow all facility safety guidelines when handling precision abrasive materials, including use of appropriate eye protection.
