3M 7100142464 Quick Change Abrasive Disc 3 Inch 20000 Rpm

Product Description

The 3M 7100142464 is a 3-inch quick-change surface conditioning disc designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive bonded to a non-woven XD substrate, it delivers high initial cut rates and sustained edge durability through demanding cycles. The open-web construction responds to surface irregularities and reduces the risk of gouging the workpiece. Licensed tradespeople and metal fabricators use this disc for deburring, blending, and prepping surfaces ahead of final coatings or finishes. The quick-change attachment system allows fast disc swaps without additional tooling, reducing downtime between operations.

This disc is suited for use on ferrous and non-ferrous metals, stainless steel, and high nickel and chrome alloys. It performs best in applications requiring high contact pressure and aggressive stock removal, such as edgework, weld blending, and surface prep in fabrication shops and manufacturing environments. The stiff resin bond maintains disc integrity under sustained load, making it a dependable option for both flat surfaces and edge work.
