3M 7100263888 Scotch-brite 5in Ceramic Surface Conditioning Disc

Product Description

The 3M 7100263888 is a Scotch-Brite Precision Surface Conditioning Disc built for demanding metalworking and fabrication tasks. It measures 5 inches in overall diameter with a 7/8-inch center hole and runs at speeds up to 12,000 RPM on right angle grinders. The abrasive material is precision-shaped ceramic grain integrated into a nonwoven web backing, which delivers consistent cut rate and extended abrasive life compared to conventional nonwoven discs. The Very Fine grade makes this disc well suited for finishing, polishing, cleaning, and radiusing operations where surface quality is the priority. Licensed trades and fabrication professionals will find this disc a reliable tool for controlled material removal without aggressive stock loss.

This disc is designed for use with right angle grinders on a range of substrates including aluminum, soft metals, carbon steel, and stainless steel. The center-hole attachment type and 5-inch diameter fit standard backing pads sized for that configuration. Its Very Fine grade targets finishing and surface refinement work rather than heavy grinding, making it appropriate for weld blending, pre-polish prep, light deburring, and cleaning applications in both production and field service environments. The blue color coding simplifies grade identification when multiple disc grades are in use at a workstation.

Compatibility

Designed for use with right angle grinders accepting 5-inch discs with a 7/8-inch center hole. Suitable for aluminum, soft metals, carbon steel, and stainless steel substrates across finishing, cleaning, radiusing, and polishing applications.

Installation Notes

This disc is installed and operated by machinists, fabricators, and metalworking tradespeople. Before mounting, confirm the grinder's rated speed meets or exceeds the 12,000 RPM disc rating and that the backing pad diameter and hole size match. Power down and disconnect the grinder from its power source before changing discs. Do not exceed the maximum rated RPM printed on the disc or packaging, and always wear appropriate eye and face protection during operation.
