3M 7000000286 Lapping Film 261X 5.0 Micron 8.5x11 in

Product Description

The 3M 7000000286 is a precision lapping film designed for controlled, uniform surface finishing across a range of substrates. Part of the 261X series, it features precisely graded aluminum oxide abrasive particles coated on a 3 mil polyester film backing. The 5.0 micron grade makes it well suited for intermediate to fine finishing applications where consistent surface texture and dimensional accuracy are critical. Each sheet measures 8.5 inches by 11 inches and is sold individually. This film is a go-to choice for technicians and tradespeople who require repeatable, controlled stock removal and surface refinement in precision work.

This lapping film is used in applications requiring fine abrasive finishing, including fiber optic connector polishing, precision optical component preparation, and fine surface conditioning of metal, ceramic, and composite substrates. It performs reliably in both bench-top and hand-lapping setups. The 261X series is available in multiple micron grades, allowing users to step through progressively finer finishes within a single product family.

Key Features

• Precisely graded 5.0 micron aluminum oxide abrasive for consistent, repeatable surface finishes
• Coated on a dimensionally stable 3 mil polyester film backing
• Sheet size of 8.5 inches by 11 inches for flexible use in bench or hand-lapping applications
• Part of the 261X series, available in grades from 0.30 to 30.0 micron for multi-step finishing sequences
• Suitable for use on metal, ceramic, optical, and composite substrates

Compatibility

Designed for use in precision lapping and polishing applications across metalworking, optical, and fiber optic finishing workflows where a 5.0 micron aluminum oxide abrasive film is required.

Installation Notes

This lapping film is used by precision finishing technicians and skilled tradespeople in controlled bench environments. Secure the film flat against a lapping plate or backing surface before use to ensure even abrasive contact. Replace the sheet when abrasive loading or visible wear reduces cutting efficiency. Follow applicable workplace safety guidelines for handling abrasive materials, including use of appropriate hand and eye protection.
