3M 7000044722 Lapping Film Disc 5 Inch Silicon Carbide

Product Description

The 3M 7000044722 is a silicon carbide lapping film disc designed for precision polishing in fiber optic connector finishing and metallurgical sample preparation. The abrasive mineral is coated onto a 3 mil polyester film backing, which provides dimensional stability and consistent substrate contact during polishing. The disc measures 5 inches in diameter and is available in multiple micron grades including 5.0, 9.0, 15.0, and 30.0 micron, allowing technicians to step through a controlled finishing sequence. Tight particle size distribution is a defining characteristic, delivering repeatable cut rates, surface finish quality, and disc service life across production environments.

This disc is suited for use in fiber optic termination and polishing operations as well as metallurgical laboratory preparation work. It performs in both manual and machine-driven polishing fixtures where a consistent, load-bearing film substrate is required. The format is compatible with standard 5-inch polishing fixtures and backing pads used in telecom, datacom, and materials science applications. Technicians working in fiber optic splicing, connector prep, or metallurgical cross-section analysis will find this disc appropriate for their finishing workflow.

Key Features

• Silicon carbide abrasive on 3 mil polyester film backing for dimensional stability
• Tight particle size distribution for consistent cut rate and repeatable surface finish
• Available in 5.0, 9.0, 15.0, and 30.0 micron grades to support multi-step polishing sequences
• 5-inch disc format fits standard polishing fixtures used in fiber optic and metallurgical applications
• Also available in sheets and rolls for alternate fixture configurations

Compatibility

Designed for use in fiber optic connector polishing and metallurgical polishing applications using standard 5-inch disc polishing fixtures and backing pads.

Installation Notes

This disc is installed and used by fiber optic technicians, lab technicians, and metallurgical prep professionals rather than field trades. Secure the disc to a clean, flat backing pad before use and verify that the polishing fixture is properly aligned to avoid uneven abrasive wear. Follow the abrasive manufacturer and equipment manufacturer guidelines for polishing pressure and step sequence when progressing through micron grades. Inspect discs for loading or tearing between uses and replace as needed to maintain finish quality.
