Norton 66252841903 Grinding Wheel Type 27 4.5in 36 Grit

Product Description

The NORTON 66252841903 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive and a resinoid bond, this 4.5-inch diameter wheel delivers consistent cutting action across a range of ferrous materials. At 36 grit, it falls in the medium grade range, making it suitable for weld grinding, slag removal, and surface blending. The 5/8-11 threaded hub fits standard right-angle grinders used daily in fabrication, welding, and maintenance trades. At 3/32-inch thickness, the wheel provides a focused grinding profile suited to flat and contoured work surfaces.

This wheel is used in metal fabrication shops, structural steel work, welding repair, and general maintenance applications. The Type 27 and Type 42 dual classification means it can be used in both flat grinding and conical configurations depending on the grinder guard setup. It is appropriate for both shop and field use by welders, pipefitters, ironworkers, and maintenance mechanics who need a reliable grinding wheel for everyday stock removal tasks.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or damage before mounting and never use a damaged wheel. Ensure the grinder is disconnected from power before mounting or removing the wheel. Verify that the grinder RPM rating meets or exceeds the wheel speed rating before operation.
