Norton 66243510641 Cut-off Wheel 2.5in Aluminum Oxide Type 1

Product Description

The NORTON 66243510641 is a Type 1 (flat) aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel. Measuring 2-1/2 inches in diameter and 1/16 inches thick with a 3/8 inches arbor hole, it fits standard die grinders used in fabrication, maintenance, and field service work. The resinoid bond and fiberglass reinforcement on both sides keep the wheel intact under lateral stress, while a 30,560 RPM maximum speed rating suits the high-RPM output typical of pneumatic and electric die grinders. At 0.05 pounds, it adds minimal weight to the tool.

This cut-off wheel is suited for light-duty precision cutting tasks where a full-size angle grinder is impractical. Common applications include cutting bolts, rods, pipe, sheet metal, and weld seam cleanup in tight spaces. The 2-1/2 inches diameter makes it well suited for die grinder work in confined areas such as engine bays, equipment frames, and mechanical assemblies. It performs on both mild steel and stainless steel, making it a practical choice for HVAC techs, pipefitters, auto technicians, and general maintenance tradespeople.

Key Features

• Aluminum oxide abrasive grain for efficient cutting on steel and stainless steel
• Type 1 flat profile for straight plunge and cut-off applications
• Resinoid bond provides consistent grain exposure throughout wheel life
• Both sides reinforced with fiberglass for structural integrity at high RPM
• 30,560 maximum RPM rating compatible with standard die grinders
• 1/16 inches thickness minimizes material loss and heat buildup during cuts

Compatibility

Designed for use with die grinders accepting a 3/8 inches arbor. Rated for cutting steel and stainless steel. Verify the tool spindle speed does not exceed 30,560 RPM before mounting.

Installation Notes

Always power down and disconnect the die grinder before mounting or removing a cut-off wheel. Inspect the wheel for cracks or chips before each use and discard any damaged wheel. Wear appropriate PPE including eye protection and a face shield when operating. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
