3M 7000044723 Silicon Carbide Lapping Disc 5 Inch

Product Description

The 3M 7000044723 is a silicon carbide lapping disc engineered for precision polishing in fiber optic connector finishing and metallurgical sample preparation. The abrasive mineral is coated on a 3 mil polyester film backing, delivering a consistent cut rate, controlled finish, and predictable service life across production runs. The disc measures 5 inches in diameter and is available in multiple micron grades, making it a standard choice wherever silicon carbide lapping is specified. Technicians and lab professionals select this disc when tight particle distribution and repeatable surface finish are required.

This disc is designed for use in fiber optic polishing applications, including connector endface preparation, as well as metallurgical polishing for cross-section analysis and sample finishing. The polyester film backing resists tearing under machine and hand lapping conditions. It is well suited for production environments where consistent results across high part volumes are necessary. The disc format is compatible with standard 5 inch lapping fixtures and polishing machines common in both industries.

Key Features

• Silicon carbide mineral on 3 mil polyester film backing for durability and dimensional stability
• Tight particle distribution for repeatable surface finish and cut rate
• Available in 5.0, 9.0, 15.0, and 30.0 micron grades to cover a range of polishing stages
• Consistent cut rate and extended disc life reduce process variability
• Available in disc, sheet, and roll formats for different application setups

Compatibility

Designed for silicon carbide lapping and polishing applications in the fiber optic and metallurgical industries, compatible with standard 5 inch lapping fixtures and polishing equipment.

Installation Notes

Discs are installed on polishing machines or hand lapping fixtures by qualified technicians or lab personnel following equipment manufacturer guidelines. Ensure the fixture surface is clean and flat before mounting to avoid uneven wear. Follow facility safety protocols when handling fine abrasive media, including appropriate respiratory and eye protection. Store unused discs flat in a controlled environment to preserve flatness and coating integrity.
