Norton 66252843609 Type 27 Grinding Wheel 4.5in Metal

Product Description

The NORTON 66252843609 is a Type 27 depressed center grinding wheel engineered for metal grinding and cutting applications. Built with an aluminum oxide abrasive grain, this wheel measures 4.5 inches in diameter with a 0.125-inch thickness and a 5/8-11 arbor bore, making it a direct fit for standard 4.5-inch angle grinders. Aluminum oxide is a well-proven abrasive for ferrous metals, delivering consistent stock removal on steel, structural iron, and weld beads. This wheel is sold individually and available in case quantities of 10, suited for job site stocking or shop supply use. Licensed HVAC service teams, pipefitters, ironworkers, and general metalworking trades rely on this wheel class for daily grinding tasks.

This Type 27 wheel is designed for use on 4.5-inch angle grinders with a 5/8-11 threaded spindle, the most common spindle configuration in the trades. It is appropriate for surface grinding, weld dressing, and deburring on mild steel, carbon steel, and similar ferrous materials in both residential and commercial job site environments. The depressed center profile allows the wheel to be used at a low angle to the workpiece, improving access in tight areas and along flat surfaces. Replaces discontinued item 076607-75911.

Installation Notes

Grinding wheels must be installed and operated by trained personnel following ANSI B7.1 safety standards and the grinder manufacturer guidelines. Always inspect the wheel for cracks or damage before mounting and perform a ring test where applicable. Ensure the grinder is fully de-energized and unplugged before changing wheels, and confirm the grinder RPM rating meets or exceeds the wheel maximum RPM before operation. Wear appropriate PPE including face shield and gloves when operating angle grinders.
