3M 00222828 Quick-change Disc 3 in Non-woven Coarse Type R 100pk

Product Description

The 3M 00222828 is a 3-inch non-woven quick-change abrasive disc designed for surface conditioning, blending, and finishing work across metal fabrication and mechanical service applications. Built with aluminum oxide abrasive in a coarse grade, it delivers aggressive material removal while the non-woven construction conforms to irregular surfaces. The Type R attaching system allows fast disc changes without tools, reducing downtime during production or repair operations. This disc is rated to 18,000 RPM and carries ACRS certification. It ships in a package quantity of 100 discs, making it practical for shop stock or high-volume service use.

This disc is suited for use in metal shops, maintenance facilities, and mechanical service environments where surface prep, weld blending, rust removal, or light deburring is required. The coarse aluminum oxide abrasive makes it effective on ferrous and non-ferrous metals. The non-woven structure resists loading on softer materials and leaves a consistent surface finish. Tradespeople working in fabrication, HVAC installation, or plumbing rough-in who need a fast-change abrasive for angle grinders or die grinders will find this disc appropriate for regular use.
