3M 7000044832 Diamond Lapping Film Disc 4.25 in

Product Description

The 3M 7000044832 is a 4.25-inch diameter diamond lapping film disc from the 3M 662XW series, designed for precision flat-surface finishing and abrasive lapping applications. This disc features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, resulting in increased durability and a faster cut rate. The 662XW construction maintains a flat cutting surface throughout its service life, which is critical for achieving consistent material removal without edge rounding. Technicians and machinists working on optical fiber connectors, precision metal components, ceramics, and other tight-tolerance surfaces rely on this disc for controlled, repeatable results.

This disc is suited for precision lapping and polishing in industrial, telecommunications, and manufacturing environments. The 7000044832 is supplied as a single disc (each unit) with a minimum order quantity of 25 pieces, making it appropriate for production environments where consistent abrasive supply is required. The 662XW series is available across multiple micron grades, including 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron, allowing technicians to select the appropriate grade for each stage of a lapping or polishing sequence.

Key Features

• Higher diamond concentration delivers increased cut rate over standard diamond lapping film
• Stronger resin bond improves disc durability and extends abrasive service life
• Flat surface geometry prevents edge rounding during lapping operations
• Long abrasive life reduces disc change frequency, supporting higher throughput
• Available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades for multi-stage finishing sequences
• Also available in rolls and sheets for alternate application setups

Compatibility

Designed as an OEM-style abrasive disc for precision lapping and polishing equipment accepting 4.25-inch diameter film discs; verify micron grade and backing compatibility with your specific lapping fixture before use.

Installation Notes

Installation and use should be performed by qualified machinists or technicians familiar with lapping and polishing procedures. Ensure the lapping fixture and backing plate are clean and free of debris before mounting the disc to avoid surface contamination. Do not apply excessive pressure during initial setup; follow the equipment manufacturer guidelines for load and speed. Store unused discs flat in a clean, dry environment to preserve abrasive integrity.
