3M 7100051422 Diamond Lapping Film Psa 9.0 Micron

Product Description

The 3M 7100051422 is a pressure-sensitive adhesive (PSA) diamond lapping film sheet designed for precision surface finishing of 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. At 9.0 micron particle size, this sheet falls in the mid-range of the 3M 668X lapping film series, which spans from 0.10 to 30.0 micron grades. Measuring 9 inches x 11 inches, the PSA backing allows the sheet to mount securely to a flat lapping plate or backing surface. It is used by precision technicians, optical fabricators, and tool-and-die shops requiring controlled, high-quality surface refinement.

This lapping film is suited for applications requiring tight surface finish tolerances on hard substrates such as ceramics, carbides, hardened steels, optical glass, and fiber optic connectors. The PSA configuration makes it a practical choice for bench lapping operations where quick sheet changes and consistent positioning are required. It is sold individually and is intended for use in production or field environments where repeatable stock removal and finish quality are critical. Minimum order quantity is 10 sheets per the supplier unit of measure.

Key Features

• PSA backing for secure, repositionable mounting to flat lapping plates or backing films
• 9.0 micron precisely graded diamond abrasive for controlled, repeatable material removal
• Polyester film backing provides dimensional stability during lapping operations
• Sheet size of 9 inches x 11 inches suits standard lapping plate formats
• Compatible with dry or light-fluid lapping processes on extremely hard materials
• Part of the 668X series, available in grades from 0.10 to 30.0 micron

Compatibility

Designed as a PSA-backed alternative to the 3M 661X diamond lapping film series. Suitable for use on extremely hard materials including ceramics, carbides, and optical substrates where precise micron-grade finishing is required.

Installation Notes

This product is installed by precision machinists, optical technicians, or fiber optic technicians performing surface lapping or polishing operations. Ensure the backing plate or lapping surface is clean and free of debris before applying the PSA sheet to avoid contamination of the abrasive layer. Peel and apply with firm, even pressure to eliminate air pockets that could cause inconsistent finish results. Follow facility safety guidelines for handling fine abrasive materials, including appropriate respiratory and eye protection when working in dry lapping environments.
