Norton 66261144056 Quick-change Disc 1 in 36 Grit Zirconia

Product Description

The NORTON 66261144056 is a 1-inch quick-change abrasive disc designed for use with Speed-Lok TS (Type S) attachment systems. Built on a flexible cloth backing and coated with zirconia alumina grain at 36 grit, this very coarse disc is engineered for aggressive material removal on metal, weld seams, and surface prep work. The Type S button system allows fast disc swaps without tools, reducing downtime during high-volume grinding tasks. This disc ships individually but is sold in multiples of 100, making it a standard consumable for production grinding environments.

This disc is suited for metalworking applications in fabrication shops, maintenance and repair operations, and field work where a compact 1-inch disc is required for tight-access grinding. The zirconia alumina abrasive is a self-sharpening grain that holds up under moderate to heavy pressure, making it a practical choice for ferrous metal stock removal and weld blending. It is typically used by metal fabricators, ironworkers, and maintenance techs working with angle grinders or die grinders equipped with a Type S quick-change arbor.

Installation Notes

Installation is performed by metalworking professionals using a die grinder or angle grinder fitted with a compatible Type S quick-change mandrel. Ensure the tool is powered off and disconnected from the air supply or electrical source before mounting or removing the disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating of the tool or disc. Eye protection and appropriate PPE are required when operating abrasive discs.
