Norton 66252842011 Type 27 Grinding Wheel 4x1/4x5/8

Product Description

The NORTON 66252842011 is a Type 27 depressed center grinding wheel engineered for metal grinding and cutting applications. Built with an aluminum oxide abrasive grain, this wheel delivers consistent stock removal on ferrous metals including steel and iron. The depressed center design lowers the grinding surface below the flange, allowing the operator to work at a shallow angle for better surface contact and control. It measures 4 inches in diameter with a 1/4-inch thickness and a 5/8-inch arbor bore. Sold individually, this wheel is a standard consumable for angle grinders used by welders, fabricators, pipefitters, and ironworkers in field and shop environments.

This wheel is suited for grinding welds, removing scale, and deburring on structural steel, pipe, sheet metal, and plate. The 4-inch diameter and 5/8-inch arbor bore fit compact angle grinders commonly used in tight spaces or overhead work. The Type 27 profile is the correct geometry for surface and edge grinding where a flat or slightly angled approach is needed. This wheel is a direct consumable replacement kept on hand in quantity for high-volume grinding operations.

Installation Notes

Mounting and replacement of grinding wheels is typically performed by the equipment operator or a qualified metalworker following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the angle grinder before changing the wheel. Inspect the wheel for cracks or chips before mounting and never exceed the maximum RPM rating marked on the wheel. Ensure the arbor nut is properly tightened using the correct spanner wrench before operation.
