3M 7100025308 5 Inch Silicon Carbide Abrasive Disc

Product Description

The 3M 7100025308 is a 5-inch silicon carbide abrasive disc designed for precision polishing in fiber optic and metallurgical applications. The mineral is coated on a 3 mil polyester film backing, which provides dimensional stability and consistent surface contact during polishing operations. Available in 5.0, 9.0, 15.0, and 30.0 micron grades, this disc delivers tight particle size distribution for repeatable cut rates, finish quality, and disc life. It is suited for applications where controlled material removal and surface finish consistency are critical requirements.

This disc is a standard product for silicon carbide polishing applications in the fiber optic and metallurgical industries. Typical use cases include end-face polishing of fiber optic connectors and surface preparation of metallurgical specimens. The disc format is suited for use with standard lapping fixtures, polishing machines, and handheld polishing tools used in lab and field environments by technicians and quality control professionals.
