3M 7000044812 Lapping Film 261X 9.0 Micron 3x600ft Roll

Product Description

The 3M 7000044812 is a precision lapping film designed for consistent, controlled material removal and surface finishing across a wide range of substrates. Part of the 261X series, this roll features precisely graded 9.0 micron aluminum oxide abrasive particles coated onto a 3 mil polyester backing film. The result is a dimensionally stable, uniform abrasive surface that delivers repeatable finishes in tight-tolerance applications. Supplied in a 3 inch wide by 600 foot roll format, it is well suited for high-volume or continuous finishing operations in manufacturing, optical, fiber optic, and precision mechanical environments.

This lapping film is used in applications requiring controlled surface finish quality, including fiber optic connector polishing, precision optical component finishing, and fine surface conditioning of metal, ceramic, and composite substrates. The 9.0 micron grade positions it as an intermediate-cut film, appropriate for stock removal before transitioning to finer micron grades. It is commonly used in automated polishing fixtures or hand lapping setups by technicians and precision manufacturing professionals.

Key Features

• 9.0 micron precisely graded aluminum oxide abrasive for controlled, uniform cutting action
• 3 mil polyester film backing provides dimensional stability and consistent abrasive contact
• 3 inch wide by 600 foot roll length supports continuous or high-volume finishing operations
• Uniform particle distribution delivers repeatable surface finishes across varied substrates
• Part of a multi-grade series available in 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades for staged finishing sequences

Compatibility

Designed for use on metal, ceramic, composite, and optical substrates requiring precision surface finishing. Compatible with standard lapping fixtures, automated polishing equipment, and hand lapping setups that accept 3 inch wide film rolls.

Installation Notes

Installation and use of lapping film should be performed by qualified technicians familiar with precision surface finishing procedures. Ensure all rotating or motorized polishing equipment is powered down and locked out before loading or changing film rolls. Follow equipment manufacturer guidelines for film tension and feed rate to prevent tearing or uneven abrasive contact. Avoid contaminating the abrasive surface with oils, debris, or incompatible compounds that could affect finish quality.
