3M 7100104619 Diamond Lapping Film Disc 4.25 Inch

Product Description

The 3M 7100104619 is a diamond lapping film disc from the 662XW series, engineered for precision flat lapping and finishing applications. This disc 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. At 4.25 inches in diameter, it delivers consistent material removal while maintaining a flat surface geometry, which is critical for achieving tight tolerances on optical, electronic, and mechanical components. Technicians and precision machinists use this disc where controlled, repeatable surface finishing is required.

The 662XW diamond lapping film disc is suited for lapping and polishing hard substrates including ceramics, carbide, glass, and fiber optic ferrules. It is commonly used in fiber optic connector end-face polishing, precision grinding of cutting tools, and surface finishing of hard materials in manufacturing and maintenance environments. The disc format is compatible with standard lapping fixtures and polishing machines. This SKU is sold individually and is part of a product family available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades to cover rough stock removal through final finish passes.

Key Features

• Higher diamond concentration delivers increased cut rate over standard diamond lapping film
• Stronger resin bond provides added durability and extended abrasive life
• Flat lapping geometry prevents edge rounding on workpieces
• Long abrasive life reduces disc change frequency and increases throughput
• Available in multiple micron grades from 0.50 to 9.0 for staged finishing sequences
• Available in disc, roll, and sheet formats for varied fixture types

Compatibility

Designed for use with standard lapping and polishing fixtures that accept 4.25-inch diameter film discs, including equipment used in fiber optic connector polishing and precision flat lapping operations.

Installation Notes

This disc is installed by precision machinists or fiber optic technicians on compatible lapping fixtures or polishing machines. Ensure the fixture platen is clean and free of debris before mounting the disc to prevent contamination of the abrasive surface. Follow the equipment manufacturer's recommended load and speed settings for diamond lapping film. Work through micron grades in sequence from coarser to finer for optimal surface finish results.
