Norton 66623325050 Quick-change Disc 1-1/2 in Aluminum Oxide

Product Description

The NORTON 66623325050 is a TR (Type III) quick-change non-woven abrasive disc from the Bear-Tex Rapid Prep series. Measuring 1-1/2 inches in diameter, it is constructed with Vortex agglomerated aluminum oxide grain bonded to a flexible, high-loft nylon web backing using proprietary Clean Bond resin technology. Rated to 30000 RPM, this disc is engineered for weld blending, surface conditioning, and finishing operations at a Very Fine (500 grit) grade. It is designed for use with TR-compatible Type R attaching systems on die grinders and handheld disc sanders.

This disc is suited for surface preparation and finishing work across a broad range of metals and composite materials in fabrication, maintenance, and repair environments. Typical applications include weld blending and finishing on stainless steel components, deburring brass and copper fittings, and surface conditioning on titanium and super alloys. The flexible nylon web backing allows the disc to conform to contoured surfaces, making it useful for work that requires consistent scratch patterns without aggressive stock removal.
