Norton 66252843611 Type 27 Grinding Wheel 4.5in Aluminum Oxide

Product Description

The NORTON 66252843611 is a Type 27 depressed center grinding wheel engineered for aggressive material removal on metal surfaces. Built with an aluminum oxide abrasive grain, this wheel delivers consistent cut rate and durability on ferrous metals including steel and iron. It measures 4.5 inches in diameter, 0.125 inches thick, and bores to 0.875 inches, making it a standard fit for most 4.5-inch angle grinders common on fabrication job sites. Licensed grinding professionals, ironworkers, pipefitters, and general fabricators reach for this wheel when they need reliable grinding performance without wheel swaps mid-job.

This wheel is suited for surface grinding, weld blending, and deburring on structural steel, pipe, plate, and fabricated assemblies. The Type 27 depressed center profile keeps the grinding face at the correct angle for flat and contoured surface work. It is sold in case quantities of 25, making it practical for contractors and shops that maintain consistent wheel inventory across multiple grinders on site.
