Norton 66243510658 Cut-off Wheel 4in Steel Stainless

Product Description

The NORTON 66243510658 is a Type 1 aluminum oxide cut-off wheel designed for fast, controlled cutting on ferrous and non-ferrous metal. Measuring 4 inches in diameter and 1/8 inches thick with a 1/4 inch arbor hole, it fits standard die grinders and operates up to a maximum of 19,100 RPM. The resinoid bond holds the aluminum oxide abrasive firmly under load, and the reinforced construction on both sides adds structural integrity during aggressive cuts. This wheel carries the Gemini designation, indicating it meets Norton quality standards for this product line. It is suited for cutting applications in fabrication, maintenance, and service work where a small-diameter wheel is required.

This cut-off wheel is intended for use with die grinders in applications involving steel and stainless steel. Its compact 4 inch diameter makes it practical for confined-space cuts, tube cutting, bolt removal, and weld tack separation. Typical users include pipefitters, welders, HVAC technicians, plumbers, and maintenance mechanics who need a reliable, small-format cutting wheel on a handheld grinder. The 1/8 inch kerf minimizes material loss and heat buildup during the cut. Sold individually, it is a straightforward replacement or single-job consumable for trade professionals.

Key Features

• 4 inch diameter with 1/4 inch arbor hole for compatibility with standard die grinders
• 1/8 inch thickness for a narrow kerf and reduced heat during cutting
• Aluminum oxide abrasive with resinoid bond for consistent stock removal on steel and stainless steel
• Type 1 (flat) wheel profile rated to 19,100 RPM maximum
• Sides reinforced construction adds durability under lateral stress
• Gemini series designation indicating compliance with Norton product performance standards

Compatibility

Rated for use with die grinders on steel and stainless steel. The 1/4 inch arbor hole fits standard die grinder mandrels accepting Type 1 cut-off wheels up to 4 inches in diameter. Always verify the grinder's rated RPM meets or exceeds the wheel's 19,100 RPM maximum before mounting.

Installation Notes

Installation and use should follow ANSI B7.1 safety standards for abrasive wheels. Confirm the die grinder's no-load RPM does not exceed the 19,100 RPM rating marked on the wheel before mounting. Inspect the wheel for cracks or chips before each use and never use a damaged wheel. Wear appropriate eye protection and a face shield; ensure bystanders are clear of the cutting plane.
