3M 7000000296 Lapping Film 261X 12.0 Micron 8.5x11 Sheet

Product Description

The 3M 7000000296 is a precision lapping film sheet designed for controlled, uniform surface finishing across a wide range of substrates. Part of the 261X series, this film features precisely graded aluminum oxide abrasive particles coated onto a 3 mil polyester film backing. The sheet measures 8.50 inches x 11 inches and carries a 12.0 micron grade, making it suited for intermediate lapping and polishing work where consistent surface finish and flatness are critical. Technicians and machinists use this film when repeatable, low-defect material removal is required on precision components.

This lapping film is used in applications requiring fine surface conditioning, including optical fiber connector polishing, precision tooling, ceramic components, and other substrates where controlled abrasion is necessary. The 12.0 micron grade places it in the intermediate finishing range, appropriate for removing fine scratches or prepping a surface before transitioning to finer grades such as 5.0 or 3.0 micron. It is commonly used in both bench-top hand lapping setups and fixture-guided polishing operations across manufacturing, telecommunications, and precision trade environments.

Key Features

• 12.0 micron precisely graded aluminum oxide abrasive for consistent cut rate and finish
• Coated on a 3 mil polyester film backing for dimensional stability during lapping
• 8.50 inches x 11 inches sheet format fits standard lapping fixtures and manual use
• Produces uniform finishes across ceramic, metal, glass, and composite substrates
• Part of the 261X series, available in grades from 0.30 to 30.0 micron for multi-stage polishing sequences

Compatibility

Designed for use as a precision lapping and polishing sheet in bench-top and fixture-guided surface finishing applications across a variety of substrate materials. No specific equipment model compatibility is stated by the manufacturer for this SKU.

Installation Notes

This film is typically used by machinists, optical technicians, and precision trade professionals performing surface finishing or polishing operations. Secure the sheet flat against a lapping plate or backing surface to prevent bunching or uneven abrasion. Inspect the film for tears or loading before each use and replace when abrasive performance degrades. Follow applicable facility safety guidelines when handling abrasive media, including eye protection and proper ventilation if dry lapping generates fine particulate.
