3M 7010309474 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7010309474 is a 5-inch diamond lapping film disc designed for precision surface finishing in demanding industrial and optical applications. Built on the 662XW platform, it features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, resulting in greater durability and a faster cut rate. The disc delivers a flat, consistent surface without edge rounding, making it well suited for technicians and machinists who require repeatable, high-quality finishes on hard materials. Available in grades from 0.50 to 9.0 microns to cover a range of finishing stages.

This disc is used in precision lapping and polishing operations where surface geometry and finish quality are critical. Typical applications include fiber optic connector end-face polishing, ceramic and carbide component finishing, and optical lens preparation. The 5-inch diameter format fits standard lapping fixtures and polishing machines used in electronics manufacturing, telecommunications, and precision machining environments. The long abrasive life reduces the frequency of disc changes, supporting higher throughput on production floors and in field-service settings.

Key Features

• Higher diamond concentration for increased cut rate over standard diamond lapping film
• Stronger resin bond provides added durability and extended abrasive life
• Flat surface contact minimizes edge rounding for consistent geometry
• Available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades
• Reduced disc change frequency supports higher throughput
• Available in disc, roll, and sheet formats

Compatibility

Designed for use on standard 5-inch lapping and polishing fixtures; part of the 3M 662XW diamond lapping film series available across multiple micron grades and substrate formats.

Installation Notes

Installation and use should be performed by trained technicians familiar with precision lapping equipment and procedures. Ensure the lapping plate or fixture is clean and free of contamination before mounting the disc. Follow equipment manufacturer guidelines for pressure and speed settings appropriate to the micron grade in use. Proper personal protective equipment, including eye protection, should be worn when operating abrasive finishing equipment.
