3M 7100074873 Quick Change Buff and Blend Hs Disc 3 Inch

Product Description

The 3M 7100074873 is a quick change buff and blend disc built for light deburring, cleaning, and final finishing on metal surfaces. Constructed from high-strength non-woven nylon material with aluminum oxide mineral, the disc maintains stiffness under pressure and resists tearing or fraying on edges and irregular contours. The open-web construction is load resistant, limiting debris buildup and extending service life. It mounts via a quick change attachment system, allowing fast disc swaps during production or repair work. Metalworking fabricators and finishing technicians are the primary users of this disc.

This disc is suited for ferrous and non-ferrous metal applications including light deburring, surface conditioning, and pre-polish finishing. The aluminum oxide mineral cuts sharply and produces a consistent scratch pattern across a range of metals. It is available in three grades: Coarse (CRS, green), Medium (MED, blue), and Very Fine (VFN, maroon), allowing selection based on the required level of aggressiveness and desired surface finish. Typical applications include weld blending, edge cleanup, and final surface prep before coating or inspection.
