Norton 66623335418 Quick-change Disc 80 Grit 4 in

Product Description

The NORTON 66623335418 is a quick-change abrasive disc from the Norton Rapid Prep series, designed for surface preparation, blending, and finishing on metal and other industrial substrates. The disc measures 4 inches in diameter and uses a Type S (SocAtt) attachment system for fast, tool-free mounting on compatible quick-change grinders and die grinders. At 80 grit, it falls in the coarse grade range, making it well suited for aggressive material removal, weld blending, rust removal, and surface conditioning. The non-woven aluminum oxide construction on a flexible nylon web backing conforms to contoured surfaces without gouging or undercutting the base material.

This disc is used in light fabrication, maintenance, and industrial surface prep applications where a conformable, non-woven abrasive is preferred over a rigid bonded or coated disc. Typical install scenarios include weld seam blending on sheet metal, pre-paint surface preparation, and deburring on ferrous and non-ferrous parts. The flexible backing makes it a practical choice when working on curved or irregular profiles. It is sold individually and is compatible with standard quick-change disc holders that accept a Type S button attachment.
