Norton 66243510640 Cut-off Wheel 2.5 in Aluminum Oxide

Product Description

The NORTON 66243510640 is an aluminum oxide reinforced cut-off wheel designed for aggressive cutting on steel and stainless steel. At 2.5 inches in diameter and 1/16 inch thick, this Type 1 (01/41) flat wheel fits standard die grinders and delivers clean, narrow cuts with minimal material loss. The resinoid bond holds abrasive grain firmly under high-speed use, and both sides are reinforced for added structural integrity at speeds up to 30,560 RPM. At 0.1 pounds, it is light enough to keep in a tool pouch without adding noticeable bulk. The Gemini specification line is recognized for consistent grain distribution and predictable wheel performance in trade environments.

This cut-off wheel is suited for metal fabrication, pipe cutting, weld preparation, and deburring tasks on steel and stainless steel in both residential and commercial service settings. The 0.25 inch arbor hole fits the collets found on most standard pneumatic and electric die grinders. Electricians, pipefitters, plumbers, HVAC technicians, and general mechanical contractors commonly keep this size on hand for tight-clearance cuts where larger angle grinder wheels cannot reach.

Installation Notes

Installation and wheel changes must be performed by a qualified tradesperson following ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or chips before mounting and never exceed the 30,560 RPM maximum speed rating. Disconnect or de-energize the tool before mounting or removing the wheel. Wear appropriate PPE including eye protection and gloves during installation and operation.
