3M 7010307690 Diamond Lapping Film 0.10 Micron Sheet

Product Description

The 3M 7010307690 is a precision diamond lapping film designed for finishing extremely hard materials to tight surface tolerances. It consists of precisely graded diamond abrasive particles uniformly coated onto a dimensionally stable polyester film backing. At 0.10 micron grit, this sheet delivers ultra-fine stock removal and a consistent, repeatable surface finish. Each sheet measures 3 inches x 6 inches and is sold individually. This product is used by technicians and machinists working on fiber optic connectors, carbide tooling, ceramics, and other hard substrates that require controlled final finishing.

This lapping film is suited for bench lapping, hand lapping, and fixture-assisted finishing operations in industrial, optical, and precision manufacturing environments. The 0.10 micron grade is typically used as a final polishing step following coarser lapping stages. Technicians working with fiber optic terminations, precision gauges, and hard metal components commonly specify this grade when surface finish is critical to performance. It performs on flat, cylindrical, and contoured surfaces when used with an appropriate backing plate or mandrel.

Key Features

• 3 inches x 6 inches sheet size suits bench and fixture lapping setups
• Compatible with extremely hard materials including carbide, ceramics, and glass

Compatibility

Designed as a precision lapping consumable for use on extremely hard materials such as carbide, ceramics, hardened steel, and optical substrates requiring ultra-fine surface finishing.

Installation Notes

This product is handled and applied by machinists, optical fiber technicians, and precision tooling specialists. Use on a clean, flat backing plate or appropriate fixture to ensure uniform contact and consistent material removal. Keep the film surface free of contamination before and during use, as debris can cause scratching at this fine grit level. Follow facility-specific procedures for handling diamond abrasive consumables and dispose of used sheets according to applicable shop or site guidelines.
