3M 7000045179 Quick-change Disc 3 in 80 Grit Ceramic Roloc Tsm

Product Description

The 3M 7000045179 is a 3-inch ceramic abrasive quick-change disc designed for use with Roloc TSM Type S attachment systems. Part of the 984F series, it features a ceramic abrasive grain bonded to a YF-weight polyester cloth backing for durability under aggressive material removal conditions. Rated at 20,000 RPM, this disc is built for high-speed grinding and blending applications on metal surfaces. At 80 grit, it falls in the medium grade range, making it suitable for weld blending, surface prep, and rust or coating removal. Installed and replaced in seconds using the Type S twist-lock button system, it is used by fabricators, welders, and maintenance professionals.

This disc is suited for use on ferrous and non-ferrous metals in light fabrication, maintenance, and repair environments. The ceramic abrasive grain self-sharpens during use, maintaining an aggressive cut rate across the life of the disc. It is commonly used on angle grinders and die grinders fitted with a Roloc TSM Type S disc pad holder. Applications include weld seam blending, edge deburring, surface conditioning, and preparation for coating or painting on structural steel, plate stock, and fabricated assemblies.
