3M 7100102265 Diamond Lapping Film Disc 5 Inch Psa

Product Description

The 3M 7100102265 is a PSA-backed diamond lapping film disc engineered for precision material finishing on extremely hard surfaces. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, delivering consistent, repeatable surface finishes across a wide range of applications. Available in grades from 0.10 to 30.0 micron, this disc is part of the 668X product line, which is the pressure-sensitive adhesive version of the 661X film. Licensed tradespeople and finishing technicians working with hard ceramics, carbides, glass, or optical components rely on this disc for its flat cut geometry and minimal edge rounding.

This diamond lapping film disc is suited for precision lapping and polishing operations where surface finish consistency is critical. Typical applications include finishing of fiber optic connectors, hard metal tooling, ceramic components, and other substrates that resist conventional abrasives. The PSA backing allows direct attachment to flat lapping plates or backing discs without additional adhesives, streamlining the finishing workflow in both production and bench environments. The 5-inch diameter format fits standard lapping fixtures used across manufacturing and optical finishing operations.

Key Features

• PSA backing allows direct attachment to flat lapping plates without additional adhesives
• Precisely graded diamond particles provide uniform, repeatable surface finishes
• Available in grades ranging from 0.10 to 30.0 micron for versatile application coverage
• Flat cut geometry minimizes edge rounding on finished workpieces
• Long abrasive life reduces disc change frequency and increases throughput
• Polyester film substrate maintains dimensional stability during lapping operations

Compatibility

Designed for use on standard flat lapping plates and backing fixtures accepting 5-inch PSA-backed abrasive discs. Suitable for lapping and polishing extremely hard materials including ceramics, carbides, glass, and fiber optic components.

Installation Notes

This disc is installed by a finishing technician or machinist onto a clean, dry flat lapping plate or rigid backing disc. Ensure the lapping plate surface is free of debris or residue before applying the PSA backing to achieve full adhesive contact. Remove the disc carefully after use to avoid tearing the film substrate. Follow facility safety guidelines for handling precision abrasive consumables, including appropriate eye protection during lapping operations.
