3M 7000045618 Quick-change Disc 1 in 36 Grit Ceramic Roloc Tr

Product Description

The 3M 7000045618 is a quick-change abrasive disc designed for use with Roloc TR and Type R attachment systems. Built on a polyester cloth backing with YF backing weight, it carries a ceramic abrasive coating rated at 36 grit, placing it in the very coarse grade range. This disc is intended for aggressive material removal on metal surfaces including weld seams, scale, and surface prep work. Licensed trades and metalworking professionals install and use this disc on angle grinders and die grinders equipped with compatible Roloc TR mandrels. The orange cloth-backed construction is part of the 3M 777F series.

This disc is suited for heavy grinding and stock removal applications in industrial, fabrication, and maintenance environments. Typical use cases include blending welds, removing rust and mill scale, and preparing steel surfaces for coating or further finishing. The 1-inch diameter makes it effective in tight access areas and contoured surfaces where larger discs cannot reach. It is commonly used by ironworkers, pipefitters, maintenance mechanics, and fabricators working in both shop and field settings.
