Norton 66254427845 Quick-change Disc 3in 36 Grit

Product Description

The NORTON 66254427845 is a Type II quick-change abrasive disc from the RazorStar series, designed for rapid material removal on metal and weld surfaces. It measures 3 inches in diameter, carries a 36-grit coarse ceramic alumina abrasive, and is built on a cloth (Y-weight) backing for durability under aggressive grinding conditions. The Type S attaching system allows tool-free disc changes on compatible right-angle grinders and die grinders, reducing downtime between passes. Rated at 20000 maximum RPM, this disc suits high-speed grinder applications common in fabrication, maintenance, and surface prep work.

This disc is suited for coarse stock removal tasks including weld blending, edge chamfering, and deburring on ferrous and non-ferrous metals. Its ceramic alumina abrasive self-sharpens during use, extending cut life compared to conventional aluminum oxide. The yellow cloth-backed construction handles heat and pressure typical of production and heavy maintenance environments. It is installed by metal fabricators, pipefitters, welders, and maintenance technicians who require consistent, repeatable disc changes across a shift.

Installation Notes

Installation is performed by the tool operator before grinding operations begin. Power down and disconnect the grinder from its power source before mounting or removing the disc. Verify the grinder spindle speed does not exceed the 20000 maximum RPM rating marked on the disc before use. Inspect the disc for damage prior to each installation and discard any disc that shows cracks, tears, or delamination in the backing.
