Norton 66243527956 Cutoff Wheel 4 in Aluminum Oxide

Product Description

The NORTON 66243527956 is an aluminum oxide reinforced cutoff wheel designed for aggressive cutting on steel and stainless steel. Measuring 4 inches in diameter and 0.045 inches thick with a 5/8 inch arbor hole, this Type 1 (01/41) flat wheel mounts directly on standard angle grinders. A resinoid bond holds the abrasive grain under load, and side reinforcement adds durability during lateral stress. The Gemini Right Cut specification indicates a hard, fast-cutting wheel grade suited for ferrous and stainless applications. Maximum rated speed is 15,280 RPM. It weighs 0.5 pounds. Fabricators, pipefitters, ironworkers, and metal tradespeople use this wheel for cut-off work on structural steel, pipe, bar stock, and sheet metal.

This wheel fits angle grinders equipped with a 5/8 inch arbor. It is suited for both shop and field use where a thin-kerf, fast cut is needed on carbon steel and stainless steel workpieces. The 0.045 inch thickness minimizes material loss at the cut and reduces heat buildup compared to thicker wheels. Typical applications include cutting rebar, pipe, angle iron, flat bar, and stainless tubing in fabrication, maintenance, and construction environments.

Key Features

• 4 inch diameter with 0.045 inch thin-kerf profile reduces material loss and heat at the cut
• Aluminum oxide abrasive with resinoid bond for fast, consistent cutting on ferrous metals
• Both sides reinforced for added structural integrity under operating loads
• Type 1 (01/41) flat wheel geometry compatible with standard angle grinder guards
• Rated to 15,280 RPM for use on common 4 inch angle grinders
• Gemini Right Cut specification engineered for steel and stainless steel cutting

Compatibility

Designed for use with angle grinders accepting a 5/8 inch arbor hole and a 4 inch diameter Type 1 cutoff wheel. Rated for cutting steel and stainless steel per the Gemini Right Cut specification.

Installation Notes

Installation and wheel changes must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and unplug or lockout the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the 15,280 RPM maximum rated speed. Use the appropriate guard and personal protective equipment including eye and face protection at all times during operation.
