Norton 66623374823 Bear-tex Rapid Prep Non-woven Disc Fine Grit

Product Description

The NORTON 66623374823 is a Bear-Tex Rapid Prep non-woven surface preparation disc designed for use on portable angle grinders and disc tools. Built from a combination of strong synthetic mesh and aluminum oxide abrasive, this fine-grit disc measures 4.5 inches in diameter and mounts via a Speed-Lok fastener for tool-free changes. The see-through open construction promotes aggressive cutting while maintaining a controlled surface finish. A patented hole pattern interrupts the cut to reduce heat generation by up to 30 percent compared to standard surface preparation discs. Scooped holes channel airflow to evacuate swarf and loose abrasive from the grinding zone, extending disc life. A proprietary thick-layer grain coating adds further wear resistance.

This disc is suited for final surface blending, cleaning, deburring, weld seam blending, and decorative finishing on a variety of metals. The fine grit rating makes it appropriate for work requiring a smooth, consistent finish after heavier material removal has already been completed. It performs on flat and contoured surfaces alike, handling the variety of shapes common in fabrication, maintenance, and repair environments. Typical users include metal fabricators, welders, and maintenance technicians working with ferrous and non-ferrous metals.

Installation Notes

Installation and disc changes should be performed by a qualified tradesperson with the grinder powered off and unplugged or battery removed. Confirm the tool's rated speed meets or exceeds the disc's maximum RPM rating before mounting. Inspect the disc for damage before each use and discard any disc that shows tears, delamination, or uneven wear. Follow applicable ANSI B7.1 safety standards for abrasive wheel use and always use appropriate eye and face protection.
