3M 7000044861 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7000044861 is a 5-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a polyester film backing, delivering a consistent, repeatable finish with every pass. The disc is suited for lapping and polishing applications where tight surface geometry, flatness, and sharp edge retention are critical. Licensed trades and finishing technicians working on hard substrates such as ceramics, carbide, glass, and fiber optic components rely on this format for controlled material removal.

This disc is used in applications requiring fine, uniform surface finishes on hard materials that conventional abrasives cannot efficiently process. The polyester film backing provides dimensional stability, which helps maintain flat surfaces and precise edge geometry throughout the lapping process. It is available as part of a broader product family that includes sheets and rolls, making it adaptable to a range of lapping fixtures and polishing equipment. Minimum order quantity is 25 units per pack.

Key Features

• Precisely graded diamond particles on polyester film for consistent, repeatable finish results
• Fast cut rate supports increased throughput on hard material substrates
• Promotes flatter surfaces and sharper edge definition compared to conventional abrasive films
• Uniform finish across the working surface of each disc
• Available in grades ranging from 0.10 to 30.0 micron to suit varying surface finish requirements
• Also available in sheets and rolls for compatibility with different lapping equipment setups

Compatibility

Designed for use on extremely hard materials including ceramics, carbide, glass, and similar substrates where conventional abrasives are ineffective; suitable for use with standard 5-inch lapping fixtures and polishing equipment.

Installation Notes

This disc is installed and used by precision finishing technicians and machinists on lapping plates or polishing fixtures. Ensure the lapping surface and fixture are clean and free of contamination before mounting the disc to avoid uneven wear or scratching. Follow the equipment manufacturer guidelines for disc mounting and rotational speed. Dispose of worn discs properly and inspect the backing for tears or delamination before each use.
