Norton 66252843604 Type 27 Cut-off Wheel 4-1/2 in Metal

Product Description

The NORTON 66252843604 is a Type 27 depressed-center cut-off wheel engineered for right-angle grinder use in metal cutting applications. Constructed with an aluminum oxide abrasive grain, this wheel delivers consistent, fast cuts through ferrous metals and general steel. At 4-1/2 inches in diameter with a 0.045-inch thickness and a 7/8-inch arbor bore, it is built for thin-kerf cutting that minimizes material loss and heat buildup at the cut line. Licensed tradespeople and experienced fabricators typically reach for this wheel when clean, controlled cuts are required on structural steel, angle iron, pipe, and sheet metal.

This cut-off wheel is suited for residential and commercial metal fabrication, structural work, mechanical contracting, and general maintenance applications. The Type 27 depressed-center profile provides additional clearance between the grinder body and the workpiece, making it practical for flush and recessed cuts. The 0.045-inch thin profile reduces cutting resistance and keeps the wheel running cooler during extended use. It is sold in a case quantity of 25 wheels, making it appropriate for high-volume shop environments or contractors who maintain a working supply on site.

Key Features

Compatibility

Designed as an OEM-style replacement and standard fitment cut-off wheel for right-angle grinders accepting a 7/8-inch arbor and a 4-1/2-inch Type 27 wheel.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety procedures. Always power down and unplug or de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel. Ensure the wheel speed rating meets or exceeds the grinder RPM rating before operation, and use the appropriate guard as required by OSHA and tool manufacturer guidelines.
