Norton 66623340077 Quick-change Disc 2in Aluminum Oxide Fine

Product Description

The NORTON 66623340077 is a 2-inch non-woven quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for surface preparation and finishing work on metal and composite materials. It mounts via a Type R Speed-Lok TR attachment system and runs at up to 30,000 RPM on compatible die grinders and handheld disc sanders. The aluminum oxide abrasive grain delivers a higher cut rate for a non-woven disc, while the high-loft nylon fiber construction extends service life. Clean Bond resin technology helps produce smear-free finishes on sensitive surfaces. The polyester backing provides flexible conformability, making it well-suited for contoured workpieces. This disc is used by metalworkers, fabricators, and maintenance technicians who need a fast-mounting, consistent surface prep solution.

The 66623340077 is intended for surface conditioning, blending, and light material removal on a wide range of materials including 300 and 400 Series Stainless Steel, Brass, Bronze, Cast Iron, Copper, Ductile Iron, Fiberglass and Composites, Gray Iron, Hard and Soft Carbon Steels, Super Alloys, Titanium, and Tool Steels. It is compatible with die grinders and handheld disc sanders equipped with a Speed-Lok TR Type R quick-change interface. The fine grade makes it appropriate for finishing passes and interpass weld cleanup rather than aggressive stock removal. Sold individually, it fits easily into a multi-disc inventory for shop or field use.

Installation Notes

Installation is performed by metalworkers and fabricators using any Speed-Lok TR Type R compatible quick-change tool. Before mounting, confirm the tool spindle speed does not exceed the disc maximum RPM rating. Inspect the disc for damage before each use and discard any disc that shows tears, fraying, or delamination. Always wear appropriate eye and face protection when operating abrasive discs.
