Norton 66254427846 Quick-change Disc 2in 36 Grit

Product Description

The NORTON 66254427846 is a Type III quick-change abrasive disc from the RazorStar series, designed for aggressive material removal in grinding and surface preparation applications. The disc measures 2 inches in diameter and features 36-grit ceramic alumina abrasive on a cloth backing with a Y-weight backing grade. Ceramic alumina abrasive cuts faster and runs cooler than conventional aluminum oxide, extending disc life under heavy use. The disc is rated to a maximum of 30,000 RPM, making it compatible with high-speed die grinders and right-angle grinders used in metalworking and fabrication environments. Installation and removal are handled without tools via the Type III quick-change attachment system, also known as Type R.

This disc is suited for weld blending, deburring, edge chamfering, and surface conditioning on ferrous and non-ferrous metals. The coarse 36-grit cut rate makes it appropriate for stock removal and initial surface preparation rather than finishing passes. The yellow cloth backing resists tearing under moderate-to-heavy pressure, and the ceramic alumina grain self-sharpens during use, maintaining consistent cut rate. Fabricators, welders, pipefitters, and industrial maintenance techs are the primary installers. Sold individually, with a minimum order quantity of 25 units.

Installation Notes

Installation requires a compatible Type R or Type III quick-change mandrel threaded into the grinder spindle.

Inspect the disc for damage before each use and discard any disc that shows cracks, gouges, or delamination.
