3M 7000044754 Diamond Lapping Film 9.0 Micron Sheet

Product Description

The 3M 7000044754 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 backing, delivering a consistent, repeatable finish with each pass. The 9.0 micron grade is suited for intermediate lapping and stock removal stages where tight surface tolerances are required. Each sheet measures 6 inches x 6 inches, making it practical for bench lapping, fixture-mounted applications, and hand lapping work across a range of industrial and trade settings.

This lapping film is used in applications where conventional abrasives cannot achieve the required finish on hard substrates such as ceramics, carbide tooling, hardened steel, optical components, and fiber optic connectors. It is commonly used by tool and die technicians, precision machinists, fiber optic installers, and maintenance trades requiring controlled material removal. The flat, flexible sheet format allows use on lapping plates, glass plates, or flat backing fixtures to maintain geometry during finishing.

Key Features

• 9.0 micron diamond abrasive grade for intermediate lapping and surface refinement
• Precisely graded diamond particles ensure consistent, repeatable finish results
• Polyester film backing provides dimensional stability during use
• 6 inches x 6 inches sheet format fits standard lapping plates and flat fixtures
• Suitable for extremely hard materials where conventional abrasives are ineffective

Compatibility

Designed as a flat-sheet lapping film for use on hard substrates requiring precision surface finishing; compatible with standard lapping plates, glass backing plates, and fixture-mounted lapping setups.

Installation Notes

Lapping film is typically applied by precision machinists, tool technicians, or fiber optic installers on a clean, flat backing surface. Secure the sheet firmly to the lapping plate before use to prevent shifting during strokes. Keep the film and workpiece clean and free of contamination between grades to avoid cross-contamination of abrasive particle sizes. Follow workplace safety guidelines for handling abrasive materials, including appropriate eye protection.
