3M 7010290614 Ceramic Fiber Disc 80 Grit 7 in

Product Description

The 3M 7010290614 is a 7-inch ceramic fiber disc designed for aggressive material removal on metal, weld seams, and hard surfaces. Part of the 987C Series, it features a resinoid bond and ceramic abrasive grain rated at 80 grit (medium grade). The threaded arbor hole accepts a 5/8-11 center hole thread, and the disc mounts via a threaded arbor hole attachment to a compatible backup pad. With a maximum operating speed of 8,600 RPM, this disc suits angle grinder applications in fabrication, welding prep, and surface conditioning work performed by metalworkers and maintenance trades.

This fiber disc is suited for use in metal fabrication shops, structural steel work, and general grinding applications requiring a consistent cut rate on ferrous and non-ferrous materials. The orange-colored ceramic grain provides cooler cutting action compared to aluminum oxide, reducing heat buildup during extended use. It is designed for use with the 3M TN Quick Change Backup Pad, which controls flex and backing support during operation.

Compatibility

Designed for use with the 3M TN Quick Change Backup Pad. The 5/8-11 threaded arbor hole attachment is the required mounting interface for this disc.

Installation Notes

Installation and disc changes must be performed by a qualified operator with the grinder fully powered down and unplugged or locked out per applicable OSHA lockout/tagout procedures. Confirm the backup pad thread size matches the 5/8-11 arbor before mounting. Do not exceed the maximum rated speed of 8,600 RPM. Inspect the disc for damage before each use and discard any disc that is cracked, torn, or delaminated.
