3M 7010325512 Diamond Lapping Film Disc 4 Inch 662XW

Product Description

The 3M 7010325512 is a 4-inch diameter diamond lapping film disc from the 662XW series, engineered for precision surface finishing and material removal in demanding industrial and optical applications. 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 polyester-backed disc maintains a flat cutting surface throughout use, which prevents edge rounding and supports consistent, repeatable finish quality. Licensed tradespeople and precision technicians working on fiber optic connectors, ceramics, hard metals, and optical components rely on this disc for controlled stock removal.

This disc is suited for wet lapping operations in production and laboratory environments where tight surface finish tolerances are required. The 662XW series is available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades, allowing the user to select the appropriate grade for roughing or finishing passes. The 4-inch diameter format fits standard lapping fixtures and polishing machines used in fiber optic termination, semiconductor finishing, and precision tooling applications.

Key Features

• Higher diamond concentration delivers increased cut rate over standard diamond lapping film
• Stronger resin bond extends abrasive life and reduces disc change frequency
• Flat cutting surface prevents rounding and maintains dimensional accuracy
• Available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades
• Compatible with disc, roll, and sheet formats within the 662XW product line

Compatibility

Designed for use with standard 4-inch lapping fixtures and polishing machines in fiber optic, optical, ceramic, and hard metal finishing applications.

Installation Notes

Installation of lapping film discs should be performed by qualified technicians familiar with precision surface finishing equipment. Ensure the lapping machine platen is clean and free of debris before mounting the disc to maintain flat contact and avoid premature disc wear. Follow the equipment manufacturer guidelines for fluid type and flow rate when performing wet lapping operations. Discard worn discs promptly, as a degraded abrasive surface can compromise finish quality and dimensional targets.
