3M 7000120956 Quick Change Disc 4.5 Inch Non-woven Ao

Product Description

The 3M 7000120956 is a non-woven quick change surface conditioning disc designed for cleaning, blending, deburring, and finishing operations on a range of substrates. Built on an open-web, non-woven fiber construction, the disc conforms to irregular and contoured surfaces without undercutting or damaging the base material. The aluminum oxide abrasive provides consistent cutting action while the open web design runs cool and resists loading during extended use. This disc is sized at 4.5 inches in diameter and is sold as a single unit. Installation and removal are handled by a hook-and-loop attachment system, making it well-suited for multi-step finishing workflows where disc changes are frequent.

This disc is used in metal fabrication, composite work, plastics finishing, and general surface preparation across a broad range of materials. It is appropriate for both shop and field use wherever a conformable abrasive is needed to condition surfaces without aggressive stock removal. Typical applications include weld blending, pre-paint surface prep, light deburring, and surface cleaning on ferrous and non-ferrous metals as well as composites and plastics. Machinists, fabricators, and maintenance technicians are the primary users of this product type.
