3M 7100310793 Fiber Disc 4.5 in 36 Grit Tn Quick-change

Product Description

The 3M 7100310793 is a precision shaped ceramic fiber disc designed for aggressive material removal on metal and other hard surfaces. Built around a premium ceramic alumina abrasive with a resinoid bond, this disc delivers consistent cut rates and extended service life compared to standard aluminum oxide products. At 36 grit extra coarse grade, it is suited for heavy stock removal, weld blending, and surface conditioning tasks. The TN quick-change attachment system allows fast disc swaps without tools, reducing downtime during production or field work. This disc is installed by metal fabricators, pipefitters, ironworkers, and maintenance technicians working with angle grinders and disc sanders.

The 7100310793 is used in residential fabrication shops, commercial manufacturing environments, and field service applications where rapid, controlled material removal is required. Common tasks include deburring, grinding welds, removing rust or mill scale, and shaping metal components. The fiber backing provides rigidity and support under pressure, making it effective on flat and moderately contoured work surfaces. It is sold individually but must be ordered in multiples of 25 units per the manufacturer minimum order requirement.
