Norton 66252842180 Type 27 Cut-off Wheel 4x0.045x0.625

Product Description

The NORTON 66252842180 is a Type 27 depressed-center cut-off wheel designed for right-angle grinders and cut-off tools. It uses a Gemini aluminum oxide abrasive grain, which delivers consistent cutting action on ferrous metals and general shop materials. The wheel measures 4 inches in diameter, 0.045 inches thick, and accepts a 0.625-inch arbor. At 0.045 inches, the blade is a thin-kerf design that minimizes material loss per cut and reduces heat buildup at the cut zone. Licensed tradespeople and fabricators working in metal fabrication, HVAC rough-in, and mechanical contracting reach for this wheel for fast, clean cuts in the field or at the bench.

This cut-off wheel is suited for use on handheld right-angle grinders in both residential and light commercial applications. The Type 27 depressed-center profile keeps the wheel hub clear of the workpiece, allowing flush and near-flush cutting without blade chatter. It is commonly used for cutting angle iron, conduit, pipe, strut channel, and sheet metal. The wheel is sold in a case quantity of 25, making it appropriate for shops and service vans that cycle through abrasives at a high rate.

Compatibility

Designed for use on right-angle grinders accepting a 4-inch Type 27 cut-off wheel with a 0.625-inch arbor bore. Verify maximum RPM rating on both the wheel and the grinder before use.

Installation Notes

Mounting and operation of abrasive cut-off wheels should follow ANSI B7.1 and tool manufacturer guidelines. Always power down and disconnect or lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting and never exceed the maximum rated RPM marked on the wheel. Wear appropriate eye protection and a face shield during operation, and ensure the guard is properly positioned before cutting.
