3M 7000044763 Diamond Lapping Film Psa 1.0 Micron

Product Description

The 3M 7000044763 is a pressure-sensitive adhesive (PSA) diamond lapping film sheet engineered for precision surface finishing and material removal. Designated as the 666XW series, it features a higher diamond concentration and a stronger resin bond compared to the standard 662XW diamond lapping film, resulting in added durability and an increased cut rate. At a 1.0 micron grade, this sheet delivers fine abrasive action suited for finishing optical fiber connectors, precision tooling, and other close-tolerance surfaces. Each sheet measures 1 inch x 5 inches. The PSA backing allows for quick, secure mounting to flat lapping fixtures or backing plates without additional adhesive.

This lapping film is used in precision finishing applications across telecommunications, electronics assembly, optics, and metalworking trades. The 1.0 micron grade is appropriate for intermediate to fine finishing stages, producing a consistent, smooth surface finish on hard materials including ceramics, carbide, and hardened metals. Technicians and skilled tradespeople installing or polishing fiber optic connectors, lapping valve seats, or finishing precision cutting tools will find this sheet sized for close-tolerance hand lapping or fixture-mounted work.

Key Features

• Higher diamond concentration compared to standard 662XW diamond lapping film for increased cut rate
• Stronger resin bond provides added durability over extended use
• PSA backing mounts securely to flat lapping plates or fixtures without separate adhesive
• 1.0 micron grade suited for fine to intermediate surface finishing
• Sheet size of 1 inch x 5 inches fits standard lapping fixtures and hand-lapping setups
• Available in multiple grades: 0.50, 1.0, 1.5, 3.0, 6.0, and 9.0 micron

Compatibility

Designed as a PSA-backed replacement and upgrade alternative to the 662XW standard diamond lapping film. Suitable for use with flat lapping plates and fixtures that accept PSA-backed abrasive sheets in 1 inch x 5 inch format.

Installation Notes

This product is installed by trade technicians and precision finishing specialists using flat lapping plates or backing fixtures. Before mounting the sheet, ensure the lapping plate or fixture surface is clean and free of debris to achieve full PSA adhesion and a flat working surface. Do not stretch or fold the film during application, as distortion will affect surface finish consistency. Replace the sheet when cut rate diminishes or when the abrasive surface shows visible wear to maintain finishing accuracy.
