3M 7010325526 Diamond Lapping Film 0.10 Micron 8.5x11 in

Product Description

The 3M 7010325526 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 base, delivering a consistent, repeatable finish across each sheet. At 0.10 micron grade, this film is intended for ultra-fine finishing and polishing stages where surface geometry and finish quality are critical. Each sheet measures 8.5 inches by 11 inches. This product is used by technicians and tradespeople who require controlled, high-precision abrasive work on hard substrates such as ceramics, carbides, optical components, and fiber optic connectors.

This diamond lapping film is suited for precision finishing applications across industries including optical fiber splicing and polishing, cutting tool reconditioning, and ceramic component finishing. The 0.10 micron grit rating places it at the fine end of the lapping film spectrum, making it appropriate as a final polishing step in a multi-stage finishing sequence. It is sold individually by the sheet and is available in grades ranging from 0.10 to 30.0 micron for full-process coverage.

Key Features

• 0.10 micron diamond particle grade for ultra-fine surface finishing
• Precisely graded diamond abrasive ensures consistent, repeatable results
• Polyester film backing provides dimensional stability during use
• Sheet size of 8.5 inches by 11 inches fits standard lapping fixtures and hand use
• Effective on extremely hard materials including ceramics and carbides
• Part of a broader micron-grade series from 0.10 to 30.0 micron

Compatibility

Designed for use on extremely hard materials requiring ultra-fine abrasive finishing, including ceramics, carbide tooling, optical glass, and fiber optic end faces. Suitable for use with standard lapping plates and fixtures that accept sheet-format abrasive film.

Installation Notes

Diamond lapping film is typically used by optical technicians, tool-and-die tradespeople, and precision maintenance professionals. Secure the sheet firmly to a flat lapping plate or backing surface before use to prevent shifting during the finishing stroke. Work through progressively finer micron grades in sequence for best results, cleaning the workpiece between grade changes to avoid cross-contamination of abrasive particles. Handle film sheets carefully to avoid folding or creasing, which can introduce surface defects.
