3M 7000120958 Quick Change Disc 4.5 in Aluminum Oxide

Product Description

The 3M 7000120958 is a Scotch-Brite Quick Change Surface Conditioning Disc designed for cleaning, blending, deburring, and finishing on metal, composite, plastics, and other materials. Built on a durable non-woven fiber construction, this 4.5-inch disc conforms to irregular and contoured surfaces without gouging, undercutting, or damaging the base material. The open web construction runs cool and resists loading during extended use, making it a practical choice for multi-step finishing workflows in fabrication, maintenance, and surface prep applications.

This disc is suited for both shop and field use where surface conditioning is required as a first or intermediate step before final finishing. The hook and loop attachment system allows for fast disc changes when cycling through multiple abrasive grades. Common applications include weld blending, light deburring, and surface preparation on structural steel, sheet metal, composites, and plastics. Fabricators, welders, and maintenance technicians are the typical end users for this type of abrasive product.
