3M 7000000299 Lapping Film Roll 9.0 Micron 4x150ft

Product Description

The 3M 7000000299 is a precision lapping film roll designed for fine surface finishing and polishing applications across a range of substrates. The film features precisely graded aluminum oxide abrasive particles coated onto a 3 mil polyester film backing, delivering consistent, repeatable surface finishes. At 9.0 micron grade, this roll is suited for intermediate lapping stages where controlled material removal and uniform surface texture are required. The roll measures 4 inches wide by 150 feet long on a 3 inch core, making it compatible with standard roll-feed finishing equipment. Weighing 2.5 pounds, it is packaged as a single roll unit.

This lapping film is used in precision finishing operations across metalworking, fiber optic connector polishing, electronic component manufacturing, and fine tooling applications. The aluminum oxide abrasive and polyester film construction make it suitable for ferrous and non-ferrous metals, ceramics, glass, and composite substrates. It is typically installed on automated or hand-fed lapping machines and flat-lap fixtures in production or bench-service environments. Technicians working on tight surface finish tolerances rely on graded lapping films like this to achieve consistent micro-finish results across production runs.

Key Features

• 9.0 micron precisely graded aluminum oxide abrasive for controlled, uniform material removal
• Coated on a 3 mil polyester film backing for dimensional stability and consistent particle presentation
• Roll format: 4 inches wide x 150 feet long on a 3 inch core for use with roll-feed equipment
• Delivers uniform finishes on metals, ceramics, glass, and composite substrates
• Available across a broad micron range including 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades

Compatibility

Designed for use with roll-feed lapping and polishing equipment that accepts 3 inch core rolls at 4 inch width. Suitable as part of a multi-stage lapping process using 3M 261X series lapping films in graduated micron grades.

Installation Notes

Installation and use of lapping film rolls should be performed by technicians familiar with surface finishing equipment and procedures. Ensure lapping equipment is powered down and de-energized before loading or changing rolls. Mount the roll securely on the spindle with the abrasive surface oriented correctly per equipment manufacturer guidelines. Avoid folding, creasing, or contaminating the film surface during handling, as surface defects will transfer directly to the workpiece finish.
