3M 7100068024 Fiber Disc 60 Grit Ceramic 4.5 in

Product Description

The 3M 7100068024 is a ceramic fiber disc designed for aggressive material removal on metal, weld seams, and fabricated surfaces. Part of the 987C series, it features a resinoid bond and ceramic abrasive grain that fractures during use to expose fresh cutting edges, maintaining consistent cut rate over the life of the disc. The 4.5-inch diameter disc mounts via a threaded arbor hole sized at 5/8-11, compatible with the 3M TN Quick Change Backup Pad. Rated to 13,300 RPM, it suits angle grinders used by metal fabricators, welders, pipefitters, and maintenance technicians. The medium grade 60-grit designation makes it appropriate for blending, deburring, and weld removal.

This disc is suited for use in metal fabrication shops, structural steel work, pipe preparation, and industrial maintenance applications. The coated ceramic abrasive on a fiber backing delivers durability under high-pressure grinding conditions. The orange disc color identifies the 987C series. It attaches to a threaded arbor hole backup pad and performs on ferrous and non-ferrous metals where a consistent, aggressive cut is required. It is sold individually with a minimum order quantity of 25 units.
