Norton 66261137454 Fiber Disc 7 in 24 Grit Zirconia Alumina

Product Description

The NORTON 66261137454 is a 7-inch zirconia alumina fiber disc engineered for aggressive material removal on metal, weld seams, and hard surfaces. Rated at 24 grit (Very Coarse), it is built for rapid stock removal where a fine finish is not required. The resinoid bond holds abrasive grain firmly under heavy grinding pressure, and the fiber backing provides the rigidity needed to maintain consistent cut through full disc life. This disc attaches via a threaded 5/8-11 arbor hole and is designed for use with the Norton AVOS Speed-Lok Back-Up Pad. It is sold individually and is installed by metalworkers, fabricators, and maintenance technicians working with angle grinders in both shop and field environments.

The NORTON 66261137454 is suited for grinding, weld blending, and surface conditioning on ferrous and non-ferrous metals in fabrication shops, structural steel work, and general industrial maintenance. The threaded arbor attachment provides a secure mount that resists disc walk under load. The 8,600 RPM maximum speed rating makes it compatible with standard 7-inch angle grinders operating within that speed range. This is a single-disc package intended for job-lot or per-task procurement.

Compatibility

Designed for use with the Norton AVOS Speed-Lok Back-Up Pad. Verify that the grinder used does not exceed the 8,600 RPM maximum speed rating before mounting this disc.

Installation Notes

A licensed or qualified technician should inspect the back-up pad and disc for damage before each use. Power down and disconnect the angle grinder from its power source before mounting or removing the disc. Confirm the grinder nameplate RPM does not exceed 8,600 RPM. Eye protection, gloves, and a face shield are standard PPE for grinding operations.
