3M 7000119203 Ceramic Fiber Disc 60 Grit 4.5 in

Product Description

The 3M 7000119203 is a ceramic abrasive fiber disc designed for aggressive material removal on metal, welds, and hard surfaces. Built on a rigid fiber backing with a resinoid bond, this disc holds up under high-pressure grinding and delivers consistent cut rate throughout its service life. At 4.5 inches in diameter with a 60 grit medium grade, it strikes a practical balance between stock removal speed and surface finish. The threaded arbor hole attaches directly to a 5/8-11 threaded backup pad, making setup fast and secure. It is rated to a maximum of 13,300 RPM. Metal fabricators, welders, and industrial maintenance techs are the primary users of this disc type.

The 7000119203 fits standard angle grinders and die grinders equipped with a 5/8-11 threaded arbor. It is well suited for weld blending, rust and scale removal, edge deburring, and surface conditioning on structural steel, stainless, and other hard metals. The disc is part of the 3M 982C series and is designed for use with the 3M TN Quick Change Backup Pad, which accepts the threaded arbor hole attachment. This disc is sold individually and is typically ordered in multiples of 25 to meet minimum order requirements.

Installation Notes

Installation is performed by metal fabricators and maintenance technicians using standard angle grinders. Always confirm the tool spindle speed does not exceed the 13,300 RPM disc rating before operating. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for cracks or damage before each use and replace immediately if any defect is found.
