3M 7000044755 Diamond Lapping Film 3.0 Micron 6x6 Sheet

Product Description

The 3M 7000044755 is a 3.0 micron diamond lapping film sheet measuring 6 inches x 6 inches, designed for precision surface finishing and material removal in tight-tolerance applications. The abrasive layer uses a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, delivering increased cut rate and longer service life. Technicians and toolmakers use this film to achieve consistent, repeatable finishes on hard substrates including ceramics, carbide, optical components, and precision metal surfaces. Each sheet is sold individually and weighs approximately 0.02 pounds.

This lapping film is suited for bench-top finishing work, fiber optic connector polishing, toolroom applications, and precision component reconditioning. The 3.0 micron grade positions it as a mid-range cut for intermediate finishing steps, typically used after coarser stock removal and before finer polishing grades such as 1.5, 1.0, or 0.5 micron. It is appropriate for both manual lapping on a flat plate and automated lapping fixture setups where consistent film geometry matters.

Key Features

• Higher diamond concentration for increased cut rate compared to standard diamond lapping film
• Stronger resin bond improves durability and extends usable sheet life
• 3.0 micron abrasive grade for intermediate precision finishing
• Sheet size of 6 inches x 6 inches fits standard lapping plates and fixture setups
• Compatible with a full grade range from 0.50 to 9.0 micron for complete finishing sequences

Compatibility

Designed for use as an intermediate-grade abrasive sheet in precision lapping and polishing sequences on hard materials such as carbide, ceramic, optical glass, and hardened metals. No specific equipment or system compatibility was provided in the product data.

Installation Notes

Lapping film should be placed abrasive-side up on a clean, flat lapping plate or backing surface, with the work piece moved against it under controlled pressure. Ensure the backing surface is free of debris that could cause uneven film contact or premature wear. Use appropriate personal protective equipment when handling fine abrasive materials. Follow the finishing sequence from coarser to finer micron grades to achieve target surface finish without skipping grades.
