3M 7000044849 Abrasive Disc 5 Inch Silicon Carbide

Product Description

The 3M 7000044849 is a silicon carbide abrasive disc designed for precision polishing in fiber optic and metallurgical applications. The disc features silicon carbide mineral coated onto a 3 mil polyester film backing, delivering consistent cut rates and a controlled surface finish across the life of the disc. At 5 inches in diameter, it fits standard disc-style polishing fixtures used in production and lab environments. Tight particle distribution across the abrasive layer ensures repeatable results from disc to disc, making this product well-suited for quality-sensitive finishing operations.

This disc is intended for use in fiber optic connector end-face polishing and metallurgical sample preparation. It is available in 5.0, 9.0, 15.0, and 30.0 micron grades, allowing technicians to select the appropriate cut for each stage of a polishing sequence. The polyester film substrate resists tearing and maintains dimensional stability during wet or dry polishing processes. Typical end users include fiber optic assembly technicians, lab metallurgists, and precision finishing professionals.
