3M 7100142279 Quick Change Surface Conditioning Disc 3 Inch

Product Description

The 3M 7100142279 is a Quick Change Surface Conditioning XD Disc designed for aggressive deburring, blending, and edge prep on metal surfaces. Built on a non-woven XD substrate with an aluminum oxide abrasive grain and a stiff resin bond, this disc delivers high initial cut rates and sustained edge durability through extended use. At 3 inches in diameter, it mounts quickly to compatible quick change tool systems, allowing fast swapping between discs without sacrificing positioning accuracy. Licensed tradespeople and fabricators working on ferrous and non-ferrous metals rely on this disc to deliver consistent, professional surface finishes in a single-step workflow.

This disc is well suited for metalworking applications including deburring weld seams, blending surface irregularities, and prepping parts for final coatings or finishes. The open web construction responds to surface contours, reducing the risk of gouging while maintaining consistent stock removal under high contact pressure. It is available in a medium grade maroon formulation and is appropriate for use on ferrous metals, non-ferrous metals, stainless steel, and high nickel and chrome alloys. Minimum order quantity is 25 discs per unit.
