3M 7000000252 Diamond Lapping Film 1.0 Micron Sheet

Product Description

The 3M 7000000252 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, delivering a consistent, repeatable finish with each pass. At 1.0 micron grade, this sheet is suited for fine finishing and polishing stages where tight surface tolerances are required. The 6 inches x 6 inches format handles flat lapping, fiber optic connector polishing, ceramic, carbide, and other hard-material finishing tasks encountered in precision manufacturing and maintenance work.

This lapping film is used in applications requiring controlled material removal and high surface quality on hard substrates such as carbide, ceramics, glass, and hardened steel. It is appropriate for use in precision grinding, fiber optic termination, toolroom work, and maintenance of hard-surface components. The polyester film backing provides a flat, conformable base that works well on lapping plates and backing pads in both shop and field settings.

Key Features

• 1.0 micron diamond abrasive grade for fine finishing and polishing stages
• Precisely graded diamond particles deliver consistent, repeatable surface finish
• Polyester film backing for dimensional stability on lapping plates and backing pads
• 6 inches x 6 inches sheet format suits flat lapping and fiber optic polishing fixtures
• Effective on extremely hard materials including carbide, ceramics, and hardened steel

Compatibility

Designed for use as a flat lapping sheet on precision lapping plates and backing pads compatible with 6 inches x 6 inches format abrasive films.

Installation Notes

This product is typically used by precision machinists, toolroom technicians, and fiber optic installation professionals. Secure the sheet flat against a lapping plate or appropriate backing pad before use to ensure even abrasive contact. Inspect the film surface before each use and replace when abrasive loading or wear is visible, as a worn film will not deliver a consistent finish. Handle with clean, dry hands or gloves to avoid contaminating the abrasive surface.
