3M 7000118429 Ceramic Fiber Disc 36 Grit 2 Inches

Product Description

The 3M 7000118429 is a 2-inch ceramic fiber disc engineered for aggressive material removal in fabrication and metalworking applications. Built on a resinoid-bonded fiber backing, it uses premium ceramic alumina abrasive at 36 grit for extra coarse cutting action. The disc mounts via a Quick Change TR (Type III) attachment, allowing fast tool-free swaps during high-volume grinding tasks. At a rated maximum speed of 25,000 RPM, it delivers consistent stock removal, weld dressing, and edge chamfering performance. Licensed metal fabricators, welders, and maintenance machinists are the primary installers and end users of this disc.

This disc is sized for use with 2-inch Quick Change TR-compatible right-angle grinders and die grinders. It is well suited to edge chamfering, weld removal, and rapid stock removal on steel, stainless, and other hard metals. The extra coarse 36-grit ceramic alumina cuts fast on flat and contoured workpieces, making it a standard choice in production weld shops and field maintenance environments where speed of material removal is the priority.

Installation Notes

This disc is installed and used by metal fabricators, welders, and maintenance machinists working with angle grinders or die grinders. Confirm the tool spindle accepts Quick Change TR (Type III) discs before mounting. Always verify the tool RPM rating meets or exceeds the disc maximum of 25,000 RPM, and inspect the disc for damage before each use. Wear appropriate PPE including eye protection and gloves when operating grinding equipment.
