Norton 66623325015 Quick-change Disc 1 in Coarse 80 Grit

Product Description

The NORTON 66623325015 is a 1-inch diameter non-woven quick-change abrasive disc from the Bear-Tex Rapid Prep series. It uses vortex agglomerated aluminum oxide grain bonded into a high-loft nylon web backing with a proprietary Clean Bond resin system. The coarse grade (80 grit) construction is designed for weld blending, light deburring, and surface finishing on a wide range of metals. It attaches via a Type R button system and is rated for use on handheld disc sanders. Installation and change-out are handled by maintenance technicians, fabricators, and metalworkers as part of standard surface prep workflow.

This disc is suited for surface conditioning and weld blending operations on ferrous and non-ferrous metals in fabrication, manufacturing, and maintenance environments. The flexible nylon web backing conforms to irregular or slightly contoured surfaces, making it practical for both flat and curved workpieces. It is rated for operation at up to 40000 RPM, which accommodates most handheld disc sanders used in light industrial applications. The 1-inch size fits compact quick-change tooling common in tight-access or detail finishing work.
