Norton 66243522502 Cut-off Wheel 4 in Aluminum Oxide 36 Grit

Product Description

The NORTON 66243522502 is a Type 1 reinforced aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel. Measuring 4 inches in diameter and 1/16 inches thick with a 1/2 inch arbor hole, this wheel mounts directly to die grinders for fast, controlled cuts. A resinoid bond holds 36-grit aluminum oxide grain in a reinforced, side-reinforced disc rated to 19,100 RPM maximum. The black wheel carries a hardness code of T and a grain structure of 4, delivering consistent stock removal on ferrous and stainless applications. Licensed trade professionals and shop technicians rely on this wheel for precise cutoff work where speed and wheel integrity matter.

This cut-off wheel is suited for use with die grinders in both shop and field environments. The 4-inch diameter and thin 1/16 inch profile make it appropriate for tight-clearance cuts on pipe, bar stock, sheet metal, and fabricated steel components. Its reinforced construction and side reinforcement add resistance to lateral stress during angled or interrupted cuts. Typical applications include metal fabrication, maintenance and repair, and HVAC or plumbing rough-in work where cutting steel or stainless steel components is required.

Installation Notes

Installation and use should be performed by trained personnel following ANSI B7.1 safety standards for abrasive wheels. Always confirm the tool spindle speed does not exceed the wheel's 19,100 RPM maximum before mounting. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Wear appropriate PPE including eye protection and a face shield when operating cut-off wheels.
