3M 7100142471 Quick Change Disc 2 Inch Coarse Ao

Product Description

The 3M 7100142471 is a Quick Change Surface Conditioning XD Disc engineered for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive on a non-woven XD substrate, it delivers high initial and extended cut rates on both flats and edges. A stiff resin bond maintains edge durability under high contact pressure, making it a reliable tool for deburring and blending operations. Licensed HVAC techs, fabricators, and metal finishing professionals install and use this disc during surface preparation steps before final coatings or finishes are applied.

This disc is suited for ferrous and non-ferrous metals, stainless steel, and high nickel and chrome alloys. Its open web construction responds to surface irregularities and minimizes gouging, making it appropriate for edgework and blending on both flat and contoured surfaces. The quick change attachment system allows fast disc swaps during production or service work, reducing downtime. Coarse grade makes it the right choice when aggressive stock removal is the priority before finish work begins.
