Standard Abrasives 7100074872 Quick-change Disc 3 in Tr

Product Description

The STANDARD ABRASIVES 7100074872 is a 3-inch diameter quick-change abrasive disc designed for surface conditioning, blending, and light material removal. Built with aluminum oxide non-woven construction, it delivers consistent cut and finish across metal, painted, and composite surfaces. The Type R (TR) attaching system allows for fast disc swaps on compatible quick-change tools without additional hardware. Rated at a maximum of 8000 RPM, this medium-grade disc handles deburring, surface prep, and weld blending tasks commonly encountered in fabrication and maintenance work.

This disc is suited for metal fabrication shops, automotive body work, and general maintenance environments where fast tool changeovers and repeatable surface finishes are required. The non-woven aluminum oxide construction conforms to irregular surfaces, making it useful for contour blending and pre-paint prep on both flat and curved workpieces. It is commonly used by fabricators, maintenance technicians, and metalworkers who need a reliable surface conditioning disc in a compact 3-inch format.
