Norton 66254482339 Quick-change Disc 1 in 150 Grit

Product Description

The NORTON 66254482339 is a non-woven quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for surface conditioning, blending, and finishing on a wide range of metals and composites. This 1-inch disc mounts via a Type R (Roloc-style) attachment system and is rated to 40,000 RPM, making it well-suited for use on die grinders and handheld disc sanders. At 150 grit, it falls in the very fine grade range, delivering smear-free surface finishes without aggressive stock removal. The aluminum oxide abrasive grain is bonded to a flexible polyester backing using Clean Bond resin technology, which resists loading and keeps the work surface clean during operation.

This disc is used in metal fabrication, welding prep, and finishing applications across residential and commercial trades. Its flexible construction allows it to conform to contoured surfaces. Compatible materials include 300 and 400 series stainless steel, brass, bronze, cast iron, copper, ductile iron, gray iron, hard and soft carbon steels, super alloys, titanium, fiberglass and composites, and tool steels. It is a practical choice for pipefitters, sheet metal workers, and fabricators who need a consistent very fine finish on diverse base materials.

Compatible materials include 300 series stainless, 400 series stainless, brass, bronze, cast iron, copper, ductile iron, gray iron, hard carbon steels, soft carbon steels, super alloys, titanium, fiberglass and composites, and tool steels.

Installation Notes

Installation is performed by trade professionals including fabricators, pipefitters, and sheet metal workers. Ensure the grinder or disc sander spindle uses a Type R quick-change interface before mounting. Verify the tool's rated RPM does not exceed the 40,000 RPM maximum disc rating before operation. Always power down and disconnect the tool from its power source before changing discs.
