3M 7100001166 Diamond Lapping Film 662XW 1.0 Micron

Product Description

The 3M 7100001166 is a diamond lapping film sheet designed for precision surface finishing and polishing applications. Sold under the 662XW series, this sheet features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, resulting in added durability and an increased cut rate. The 1.0 micron grade makes it suitable for fine-stage finishing passes where tight surface tolerances are required. Each sheet measures 6 inches x 6 inches and is sold individually. Technicians working in fiber optic connector polishing, precision tooling, and similar finishing trades rely on this film to achieve consistent, repeatable results across a range of substrate materials.

This lapping film is used in applications requiring controlled material removal at a fine micron level. The 1.0 micron grade fits into a progression of grades ranging from 0.50 micron up through 9.0 micron, allowing technicians to step through multiple stages of abrasive finishing. Typical use cases include fiber optic ferrule polishing, lapping of precision metal and ceramic components, and finish work on optical surfaces. It is suited for both bench and fixture-mounted polishing setups in professional shop or field environments.

Key Features

• Higher diamond concentration for increased cut rate over standard diamond lapping film
• Stronger resin bond for added durability during extended use
• 1.0 micron grade for fine-stage precision finishing
• 6 inches x 6 inches sheet size for versatile fixture and hand-lapping use
• Part of a multi-grade series available from 0.50 to 9.0 micron for full finishing progressions

Compatibility

Designed for use as a precision abrasive lapping sheet in fiber optic polishing, ceramic and metal surface finishing, and related precision material-removal applications where controlled micron-level abrasion is required.

Installation Notes

This product is handled and used by precision finishing technicians, fiber optic splicing crews, and tool-and-die professionals. Secure the sheet to a flat lapping plate or polishing fixture before use to ensure consistent surface contact and uniform material removal. Inspect the film surface before each use and replace when diamond abrasive shows visible wear or loading. Follow applicable shop safety practices when handling precision abrasive materials, including eye protection.
