Norton 66254427833 Quick-change Disc 3in 36 Grit Ceramic Alumina

Product Description

The NORTON 66254427833 is a Type II quick-change abrasive disc from the RazorStar series, designed for aggressive material removal in grinding and blending applications. The disc measures 3 inches in diameter and uses ceramic alumina abrasive at 36 grit, placing it in the coarse grade range. A cloth backing rated Y-weight provides durability and flexibility under load. The Type S attaching system allows fast disc swaps without tools, reducing downtime during high-volume work. Rated to 20,000 RPM, this disc is suited for use with compatible right-angle grinders and quick-change mandrels used by fabricators, pipefitters, and maintenance technicians.

This disc is intended for coated abrasive applications on metal substrates where rapid stock removal is the priority. The ceramic alumina grain self-sharpens during use, maintaining cut rate over the life of the disc. The yellow cloth backing holds up to the heat and pressure generated in heavy grinding passes on structural steel, weld seams, and pipe. Minimum order quantity is 25 discs, with a package quantity of 1 per unit sold.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the grinder powered off and disconnected from its power source. Verify that the tool's rated RPM meets or exceeds the disc's 20,000 RPM maximum before mounting. Inspect the disc for damage before each use and never operate a cracked or torn disc. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive disc mounting and guarding.
